Welcome everyone to Upwork's fourth quarter and full year 2023 earnings call. I'm excited to review our accomplishments for the year and speak to our plans for the future. We gained further momentum in the fourth quarter. Fourth quarter revenue of $183.9 million grew 13.9% year-over-year, reflecting accelerating growth over the past three quarters.

Full year revenue grew 11.5% year-over-year to $689.1 million. We continued to demonstrate strong profitability with GAAP net income of $46.9 million and adjusted EBITDA of $73.1 million for the full year, which is the highest adjusted EBITDA result in our company's history.

This success was made possible by our dedicated Upwork team and I want to thank them for their disciplined efforts. 2023 was a significant year for the world of work.

As the world's largest work marketplace, Upwork played a critical role in helping the more than 850,000 clients and millions of independent professionals we serve, adapt to new realities and modernize how they work. There are three key areas of focus that we saw pay dividends in 2023, AI investments, partnerships, and ads and monetization.

We built innovative new AI-powered features and platform experiences across every category of work. In the fourth quarter, we opened up the waitlist for Upwork Chat Pro, a work tool powered by OpenAI GPT-4 and embedded into the Upwork experience to help customers solve challenging tasks, boost productivity, and do their best work faster.

We've already received over 150,000 signups, and the wait list is growing every day. Our AI-powered job post generator tool has also proven to be a major boost for clients, significantly increasing task completion speed and improving results.

And lastly, findings from the first version of our proposal tips tool showed that freelancers using it secured work at a higher rate than those not using it.

Despite only being available for a short time, these AI-powered tools are already having a strong positive impact, and we are committed to further developing this exciting technology for the benefit of our customers. We also forged constructive partnerships in 2023 with specific objectives in mind.

The first objective involved establishing Upwork as a go-to destination for experts in different types of work. This included launching our third quarter partnership with OpenAI. Since signing OpenAI, we have signed a dozen additional partners through a similar model with more on the horizon.

The second objective was establishing partnerships with companies such as Adobe, Amazon, Miro, Jasper, and ClickUp, aimed at increasing the speed and quality of work delivered on Upwork. While this strategy is in its early stages, customer feedback has been extremely positive.

Finally, on ads and monetization, we made a strong push to enable talent on our platform through a number of offerings that empower them to stand out from the crowd and highlight their unique skills.

Our suite of ads and monetization products was the fastest growing revenue stream for Upwork in 2023, and the efficacy of these tools is being proven out in real time.

Using these products, talent can signal to prospective clients that they are ready to start a project immediately, boost proposals to secure work, and promote their profiles at the top of a client's search results when a client is searching for talent.

When a client sends invitations to collaborate with freelancers using an availability badge, those invitations are accepted 77% more often. A successfully boosted proposal increases a freelancer's chance of getting hired by approximately 20%.

And finally, thanks to ongoing enhancements to our Freelancer Plus subscription offering for talent, we saw enrollments increase 76% year-over-year. We're excited to grow this suite of products and support our customers in the year ahead. Turning to Enterprise, we continue to be well positioned to capture share and drive value.

In December, we announced an initiative to make it easier for Enterprise customers to use Upwork within their existing workforce management systems. We launched partnerships with major vendor management system, or VMS platforms, SAP Fieldglass, and Flextrack within our Enterprise Suite.

We plan to drive further Enterprise growth through these integrations and by expanding these arrangements to additional VMS partners to be announced this year.

The differentiation of our enterprise suite is what attracted 31 leading organizations like Instacart, Checkout.com, and New York University to become a new enterprise client in the fourth quarter, innovating how they work at scale.

We are proud of the foundation of efficiency and pace of acquisition we built for the Enterprise business in 2023 and are confident in our plans to re-accelerate this business in 2024. Of course, one trend dominated the discourse more than any other last year, the rise of artificial intelligence.

Last summer, when we unveiled the first set of AI innovations in our ecosystem, we said what we believed AI would be a game changer for work, deliver major wins for professionals and companies alike, and be an avenue for the world to work smarter.

We saw that AI tools held tremendous promise to enhance work experiences and enable professionals to be more productive and fulfill their potential. While still early in the journey, my conviction in that vision is stronger than ever.

We have made significant progress toward our goal of making Upwork the preeminent destination for AI-related talent and work. We're also continuing to expand our range of AI-based solutions that supercharge our customers' ability to get work done.

In Q4, we acquired AI startup Headroom and welcomed Headroom's founder, Andrew Rabinovich, as our Head of AI and Machine Learning. Andrew is one of the world's leading scientists in deep learning and computer vision.

He worked for years in leadership positions at Google Brain and Magic Leap and his background and expertise will enable us to accelerate our work to reimagine how we serve customer needs using human-centered AI as the new building block for innovation.

This year, with our expanded internal AI team, we are fundamentally re-envisioning the full Upwork experience. We look forward to sharing more on our exciting progress and vision in the coming year. As we look to the year ahead, we are focused on three strategies that guide our investments.

These strategies are, first, win key customer and work segments via specialization. Upwork is already known for the breadth and diversity of our marketplace. This year, we are executing on the opportunity to layer in greater category specialization to enable high value customer and work offerings to thrive more readily in our ecosystems.

You've seen us take early steps in this direction with our focus on the AI talent vertical last year. We helped clients more easily connect with top tier AI talent via targeted partnerships with organizations like OpenAI, feature launches like consultations for AI work and a dedicated talent storefront with our AI services hub.

These efforts led to 70% growth in GSV in the AI and machine learning subcategory on Upwork and are the makings of a playbook for continued specialization approaches in this and other categories across our marketplace. Our second strategy is to build the world's most innovative work platform.

We're pursuing bold innovations that use the newest technologies to remove friction and enhance the light among our customers as evidenced by our already launched features and plans to leverage AI to reimagine the Upwork experience.

In addition to our own internally developed apps and features, we are leveraging partners both to distribute talent on Upwork into third-party ecosystems and to empower talent on our marketplace with access to cutting edge tools. This year, we will further expand our partner ecosystem for customers.

Our third strategy is to build a foundation for ongoing profitability growth over multiple years. We are in the early chapters of our ads and monetization journey, and we'll continue building on the strong foundations we have established to unlock more value for customers and shareholders over time.

In 2023, we were successful in our shift to profitability, delivering a 16.6% adjusted EBITDA margin and Q4, and we remain committed to an enduring focus on expanding margin this year and in years to come. These are the pillars that will guide Upwork in 2024. I look forward to providing updates as we progress through the year.

With that, I will turn it over to Erica to review our financials..

Thanks, Hayden. I'm delighted to be here to share more specifics on our strong financial momentum as we enter into a promising 2024. 2023 was a year of heightened uncertainty across the world and in business. Marked by volatility in geopolitical events and capital markets, it was an environment where the rules of the game change rapidly.

Within this dynamic, we moved to focus our business on adjusted EBITDA margin and free cash flow generation with tremendous success. In just six months, we moved from negative profitability to a business with adjusted EBITDA margins in the high teens.

We showed strong operational agility, quickly identifying opportunities for efficiencies across our business. Our focus on greater efficiency is yielding tremendous results. Our performance marketing engine is working better than ever.

In Q4, we saw 20% growth in our new client starts driven by performance marketing, while our CAC in the same period improved by 24% year-over-year. We also had excellent success with higher value client segments, which we expect have an outsized impact on revenue and LTV.

And in enterprise sales, we were able to increase our client acquisition in Q4 even with our rationalized sales force. These positive actions helped to drive total active client growth of 5% year-over-year in the fourth quarter. Within the dynamic market environment in 2023, we turned our business into one of steady growth.

For the full year 2024, we expect to continue this progress, producing strong year-over-year growth in active clients, revenue, adjusted EBITDA, and adjusted free cash flow. Our momentum exiting 2023 and our plan for 2024 give us conviction that we can provide strong business results and serve our customers even in uncertain economic conditions.

This confidence is based on our growing business efficiency, our culture of innovation, and the pipeline of new products that we have planned for 2024 and beyond. For the fourth quarter, GSV again exceeded $1 billion and was $4.1 billion for the full year 2023.

Fourth quarter GSV growth was positively impacted, in part by the timing of client payments to freelancers, which included an additional week in Q4 versus the fourth quarter of 2022. Revenue growth again showed sequential acceleration, growing 13.9% year-over-year to $183.9 million, compared to 10.8% growth in Q3.

Marketplace revenue was $157.5 million. Turning to our enterprise business unit, I want to note that in accordance with our internal operating model, we are now reporting enterprise revenue separately from marketplace revenue and the business unit includes both managed services and enterprise solutions revenue.

In the fourth quarter, total enterprise revenue was flat year-over-year at $26.4 million, which reflects the ongoing macro impacts to this customer segment that we've highlighted throughout 2023. Enterprise revenue increased modestly from Q3 to Q4. Our active client base continues to grow.

We added 15,000 new active clients in the fourth quarter of 2023, ending the year with approximately 851,000 active clients. Underpinning this growth in the fourth quarter, we had the strongest year-over-year growth in new client acquisition and reactivated clients in more than two years.

Only about a quarter of our new client acquisition comes from performance marketing, so we are also seeing strong organic growth. I want to spend a moment to provide some detail on GSV dynamics.

While we continue to see a slight decline in GSV per active client, this is partially attributable to the mix shift to newly activated clients who have lower spend early in their life cycles. Our average client increases their spend on our platform over time. So this new client acquisition is an important indicator of future growth.

GSV per newly active client was up modestly year-over-year in the fourth quarter. Non-GAAP gross margin declined slightly on a sequential basis, largely associated with one-time items, but improved nicely year-over-year, both for the fourth quarter of 2023 and also for the full year.

Q4 non-GAAP gross margin of 75.3% increased 60 basis points year-over-year. Full year 2023 non-GAAP gross margin of 75.5% increased 120 basis points year-over-year from 74.3% for the full year in 2022.

Non-GAAP operating expense was $111.8 million in the fourth quarter, representing 61% of revenue, compared to $121.6 million or 75% of revenue in the comparable prior year period.

For the fourth quarter, non-GAAP R&D expense was $39.6 million, increasing 16% year-over-year as we continued to invest in the product innovation and platform enhancements that Hayden has discussed.

Non-GAAP sales and marketing expense of $44.9 million declined 24% year-over-year as we maintained our strategy of efficient growth and non-GAAP G&A expenses of $25.1 million grew 15% year-over-year, coming off of two quarters of negative year-over-year growth as we filled some key positions and executed various projects in the fourth quarter.

Our provision for transaction losses remains steady at $2.1 million for Q4, representing just 1% of total revenue. Adjusted EBITDA was $30.5 million in the fourth quarter, representing a margin of 16.6%. For the full year 2023, adjusted EBITDA was $73.1 million, our highest ever.

Cash, cash equivalents, and marketable securities was approximately $550 million in the fourth quarter, down slightly from approximately $555 million in the prior quarter. This decline is due to the timing of client payments to freelancers that I mentioned earlier.

Cash as of January 31st of this year was $608 million, which is more indicative of our growing cash balance trends [than the] (ph) end-of-year result. We are pleased that our profitable business model is translating to GAAP earnings per share growth, which includes the impact of stock-based compensation.

For the fourth quarter of 2023, fully diluted GAAP earnings per share was $0.13, and for the full year 2023, it was $0.06 cents. I'm also happy to announce the disclosure of a new metric, adjusted free cash flow. We are starting to report this metric to reflect our commitment to growing profitability and the strong cash yield of our business.

Our adjusted free cash flow for the full year 2023 was $48.3 million. Please refer to the key definition slide in our earnings presentation for further detail on the calculation of adjusted free cash flow. Turning to guidance.

For the first quarter of 2024, we expect to produce revenue in the range of $183 million to $188 million, representing 15% year-over-year growth at the midpoint. And for adjusted EBITDA, a range of $28 million to $32 million, which represents an adjusted EBITDA margin of 14% at the midpoint.

We expect first quarter of 2024 non-GAAP diluted EPS to be between $0.17 and $0.19. For the full year 2024, we are guiding revenue to a range of $760 million to $780 million, representing 12% year-over-year growth at the midpoint. And for adjusted EBITDA, a range of $125 million to $135 million, representing a margin of 17% at the midpoint.

I want to highlight that the cadence of quarterly sequential revenue growth is expected to moderate slightly in the back half of 2024. This is primarily due to lapping of the pricing change that we have discussed on prior calls.

Our year-over-year growth and adjusted EBITDA margin reflects the profitability of our business model and our commitment to durable profitable growth. We expect full year 2024 non-GAAP diluted EPS to be between $0.77 and $0.81. Stock-based compensation is expected to be in the range of approximately $20 million per quarter for 2024.

As we look beyond 2024, it's important to note our key financial priorities. From a top-line perspective, we will be focused on driving growth through innovations in our marketplace offering and driving re-acceleration in our enterprise business unit. At the same time, we will maintain our commitment to growing profit margins.

As I've dug into our business over the past year, I continue to have unwavering conviction in our ability to produce durable, profitable growth with expanding margins over multiple years. While we have made great progress in 2023, our journey to increase both efficiency and productivity in this business is still in the early innings.

I see many opportunities for ongoing operating leverage through increasing scale, growth of new revenue streams, and ongoing productivity and efficiency improvements.

I'm excited about the growth we have planned for 2024, and we as a management team are committed to producing value for our customers, for our employees, and for our shareholders on an ongoing basis. I want to thank our fantastic team at Upwork for their tireless commitment to profitability, growth, and innovation.

And with that, we'd be happy to take your questions..

Thank you. [Operator Instructions] Our first question today will be coming from Maria Ripps of Canaccord. Your line is open..

Great, thanks so much for taking my questions. First, I appreciate all the color in terms of guidance.

Anything you can share about maybe GSV growth this year? And then maybe help us understand what's included in your revenue guidance in terms of contribution from your take rate expansion?.

Yeah, sure. Thanks, Maria, and hi. So first and foremost, I'll say for GSV growth in 2024, we do expect to drive some modest year-over-year growth in GSV in 2024. Look, as we all know, we're coming out of a couple of really volatile years in the broader economic environment in which a lot of companies saw impacts to their growth.

But we're really confident that we have the right strategy in place to grow GSV over the long term.

Just in terms of what we're contemplating from revenue growth associated with take rate in 2024, obviously we do expect, I think as everyone is pretty well acquainted with the strategic change in our pricing to a flat fee price that we announced in 2023, at the beginning of this year, the remaining 5% contracts did step up to 10%.

And so we do expect a step up in take rate from Q4 into Q1. So we'll expect some tailwinds from take rate ongoing into 2024. And just overall, I would say the dynamics of that price change have been extraordinarily good. And it really reflects the health and the strengths of the platform..

I'd add Maria that as we think about GSV growth in 2024 and beyond, there's really two levers that we're focused on. The first one is around winning key customers and work segments with specialization of our product and go to market.

And you saw us executing on that already last year with the playbook in the AI category in particular, which really led to the 70% growth in the AI machine learning subcategory, which we mentioned.

So we're going to be expanding that playbook this year, and I think that will start to contribute to that GSV growth this year, but also ramp into future years. The other strategy we're focused on is building the world's most innovative work platform. And there's a tremendous opportunity around that.

With our AI strategies, we did acquire the company Headroom in Q4, and that's really accelerating our entire roadmap around innovating the platform and watching new features. We have a number that we already put out in Q4, but again, the product pipeline there is really robust.

So we're very excited about how that's going to layer in over the coming years..

Got it, that's very helpful. And then maybe secondly, you've talked a lot about sort of new ad products and things like Connect that are driving take-rate extension on the freelancer side. But I'm just wondering whether there is any opportunity to introduce maybe additional products on the client side to drive for the take-rate expansion.

And then more broadly, how are you thinking about your long-term pricing power on both sides of the marketplace?.

I'd say we're still very early in the ads and monetization journey. I think what we saw in 2023 was very exciting in terms of the momentum with those products. And certainly, you're right, we focus more on some of the talent side features and functionality, which suggests there is a lot more we can do on the client side as well.

So I think there's more to come there. We think this is early innings. Every healthy marketplace seems to have very robust ads products. And we believe we can build that, too, as evidenced by the progress we've already made. So more to come there. This is definitely something that we're leveraging this year.

And in terms of pricing power, I think the success of our pricing changes over the course of the last year have already demonstrated, I think, that we have a good handle on what that pricing power looks like in the marketplace and that the value of the offering is really robust.

All of the pricing changes we've made have really resulted in changes in line with our expectations in terms of adoption, churn rates, et cetera. There's been no surprises and those have been a resounding success.

So we're going to continue to lean into the opportunities there to create value both for shareholders, but also for customers through these types of products..

I just had one more nuance there, which is the reason we talk about ads and monetization is that these products are kind of multi-dimensional, right? We have what would be considered probably more traditional ads products, like the boosted proposal product that's shown really nice growth.

We also have some of our new subscription products with Freelancer Plus, where we're offering new value props to our freelancers and seeing really good uptake there. And I think that there's a lot more we can do with some of these products, and so that's one of the things that gives us confidence in kind of growing these revenue streams over time..

Got it. That's very helpful. Thank you for the color..

Thank you. One moment for the next question. And our next question will be coming from Bernie McTernan of Needham & Company. Your line is open..

Great. Thank you for taking the questions. Just wanted to dig on to -- dig in on performance marketing a bit. Thought it was some pretty interesting comments that you guys made in terms of the return that you're seeing. And so just wanted to see if that was macro driven or if it's really changes in what you're doing in performance marketing.

And I think it's the latter, so just any tangibles or specifics you could give would be really helpful. Thank you..

Yeah, I definitely don't think it's macro driven at all. I think that the team has spent a lot of time optimizing the performance marketing spend. Obviously, we've ramped down our brand spend in 2023 and really focused in on that performance marketing engine.

And we're seeing benefits on multiple fronts, right? So we're seeing our CAC, as I noted in the prepared remarks, our CAC is down 24% year-over-year. We also -- we're also accessing the customers that we are adding are coming from higher value segments, kind of in the SB plus segments.

And so I think all these factors together are just reflecting the fact that our performance marketing investments and the engine itself. We did a lot of work building new models in 2023, so all those things combined are really driving momentum there..

Understood, and then just on enterprise, given the change in reporting, it will be a bit more explicitly modeled now.

I know re-excelling that growth is a priority, but just any other color to give just in terms of where you think that business can go over the next couple of years?.

Yeah, Bernie, I think we expect to see modest growth in the business in 2024 with acceleration at the end of the year and into 2025.

Through the course of 2023, we were really focused on driving efficiency and productivity of the business, particularly on the land side, and that did yield the addition of 31 new logos in Q4, which is our highest in the year. And I feel good about that, given that it's still a fluid macro environment.

And despite all of that, our go-to-market improvements have definitely been effective. This year, we're also extremely focused on improvements on the expand side of our business, which really drives up spend per client account.

And as you might imagine, this takes longer to get the results, but we have been taking steps such as our VMS integration partner launches in December, and those will kind of continue to expand and have impacts through this year and help drive that modest acceleration that we expect this year..

Great. Thanks, Hayden. Thanks, Erica..

Thanks..

Thank you. One moment for the next question. Our next question will be coming from Andrew Boone from JMP Securities. Your line is open..

Thanks so much for taking my question. It's great to see marketplace GSV accelerate from 3Q to 4Q.

Is there any help you can provide as we think about cohorts that are underlying that and just a more stable macro and how cohorts are responding?.

So I do want to emphasize on GSV, number one, as I said, we are expecting kind of modest year-over-year growth in 2024 on GSV front.

In Q4 of 2023, we did see, and I talked a little bit about this in the prepared remarks, we did see some benefit on a year-over-year growth rate point of view because of the timing of payments from clients to freelancers and the day of the week that happens. Because there are 14 Sundays in Q4, the quarter ended on a Sunday.

We did get a modest uptick in GSV growth in Q4 because of that. So we do expect for GSV growth to moderate just a little bit, still be up in Q1, but a little bit to a lesser degree as we go into the year..

Thanks, And then I had a big question -- a big picture question maybe for Hayden.

If I think about a platform fee of 10% and I compare that to 5% or 20%, is that the right comparison as I think about the potential for you guys to continue to increase price on the platform? Is there anything else we should be thinking about as we think about the relativity of pricing versus competitors in a broader picture sense? Thanks so much..

Yeah, Andrew. We're very focused on ensuring that the pricing that we have really aligns with our model, our products, and the value we create for customers, which is a pretty different model than Fiverr, which is we have long-term high-value relationships here, and we monetize those through a variety of mechanisms.

So I would say we are early still in unlocking the full value as you mentioned earlier around things like as in monetization which are a different vehicle for monetizing things like [time and attention] (ph) on our platform. And certainly there is room for take-rate expansion through vehicles like that one.

However, we're not contemplating changes to our fee structure right now. I think we did a really great job with moving to the 10% platform fee. It has been extremely successful on all the dimensions that we've been able to see and measure and I think it's a good place to be right now.

But there are other ways that we can continue to create value and monetize that value for customers and we're very focused on doing that this year and in years ahead..

Great. Thank you..

Thank you. One moment for the next question. Our next question will be coming from Kunal Madhukar of UBS. Your line is open..

Hi, thank you for taking my questions. One, in terms of the jobs that the freelancers are getting from the new clients that you added, is that any different in nature from the jobs that your traditional client base used to do? So that is one part.

And then another part of the same thing would be, in terms of duration of the projects, in terms of the amount of the total project, in terms of the rate per hour, do you see any difference between new clients versus older clients? And then I have a housekeeping question on the balance sheet side.

Want to understand, we get the adjusted free cash flow measure and that kind of reflects the delta because of the extra Sunday or the extra week.

But you have funds held in escrow, which went up significantly, trade and client receivables which went up significantly, and deferred revenue which went down significantly, even compared to the recent past. So can you talk about that too? Thank you..

All right, Kunal, packed a lot in there, so let me start to break it down. So let's start with your first question in terms of the jobs that freelancers are getting from new clients. So I wouldn't say that the new clients coming on the platform, which we do anticipate to be a nice strong growth driver for GSV going forward.

I wouldn't characterize that there's any significant mix shift in Q4 with the new jobs that clients are hiring for. I think just in general -- that the general dynamics of the platform that we've been seeing over the last couple of quarters are persistent with new client acquisition.

And those obviously are that AI-related jobs are one of our biggest growers. And we actually also continue to see some pretty interesting dynamics on the platform. Some of our biggest growth categories in Q4 were actually categories that some of the conventional wisdom thought might get disrupted by AI, but we're not seeing that.

Things like legal, things like logos for marketing and sales, other things like that are actually showing good, nice, healthy growth dynamics in Q4. So, and that's consistent with the way that we're seeing client ads come onto the platform as well.

In terms of duration and the kind of total project totals that you asked, similar to last quarter, we saw on a sequential basis the average hours for contracts just increased ever so slightly quarter to quarter. And overall, I would say that those dynamics remain pretty persistent over time.

And I'm just trying to look at my list of your questions here. Rate per hour also is pretty flat quarter to quarter, so not a lot to point to there.

And then on the questions on the balance sheet, so just for clarity's sake on the adjusted free cash flow adjustment and why we did it, first and foremost, the reason that we are making this adjustment to free cash flow is to make sure that we are truly reflecting our strong and growing cash position, which we're committed to driving on an ongoing basis.

The reality is that the day of the week in the -- depending on the day of the week that the quarter ends on, we may have a significant but temporary fluctuation in cash flow from operations because of the pre-funding of client payments to freelancers in our escrow account. So this happened in Q4 when the quarter ended on a Sunday.

And the reality is that that pre-funding then gets paid back within days each week. And so that's why there's a little bit of fluctuation and it can show quite a difference in cash balances compared to what actually ends up in our corporate cash account. So hopefully that clarifies that question.

The reduction in deferred revenue, that is consistent with the reduction that we've been seeing quarter-to-quarter on an ongoing basis and it's part of the revenue recognition that we're seeing from the tiered -- from the former tiered pricing change now to this flat fee pricing change.

So hopefully -- I know I also packed a lot of answers into that question. Hopefully, I covered everything for you..

Thank you. No, in fact, if I could follow up. So then when we look at deferred revenue, we look at deferred revenue going down.

Does that kind of imply that maybe the total number of projects that are longer term projects, the value of those projects is going down?.

No, no, that is not accurate.

The reason that the deferred revenue has declined is because we -- because of the dynamic of tiered pricing versus flat fee pricing, in the past we were required to defer more revenue because we were -- different contracts were priced at different rates and we're no longer required to do that with our new flat fee pricing..

Thank you so much..

So it does not have nothing to do with duration. Okay, yeah, sure, no problem..

Thank you. Thank you..

Yep..

Thank you. One moment for the next question. And our next question will be coming from Ron Josey of Citi. Your line is open..

Great, thanks for taking the question. Maybe, Hayden, two higher level questions, and one on AI and then one on ads products. Just on AI, we're just seeing significant traction in the number of tools and products that Upwork offers across the buyers and freelancers.

So can you just tell us maybe how this is changing or improving the overall supply and demand and just the vibrancy of the marketplace? That's on AI tools. And then on ad products, clearly, the ability badges, business proposals are having a good impact here.

Longer term, where do you think -- where can advertising go as a percentage of revenue, given your comments on just the complementary aspect to marketplaces. Thank you..

Sure, Ron. On the AI front, we're seeing really good traction so far in terms of the adoption of the tools that we've been launching for talent. So, Upwork Chat Pro, which was built on OpenAI’s GPT-4, has more than 150,000 signups.

We've seen tools like Jasper, Adobe Tools, Amazon CodeWhisperer, and others definitely getting a lot of trial interest from talent. And overall, as with this platform shift to AI, what we've seen in other previous shifts around new tools and technologies, freelancers are always the fastest to move these technologies and ramp up their skills.

And so this is what's happening right now. They're eagerly adopting these tools and really using them to drive performance metrics around productivity and quality of work. So even though it's still early days in some of this, the indicators are there that this is happening.

And we're going to continue to pursue our strategy this year and empower our talent with the best possible tools out there. To your second question on ad products, this is an interesting question for us and certainly we're thinking a lot about it.

If you look at companies like Instacart or others, I think in their [F1] (ph) they said they had something like 25% or 28% of their revenue coming from ads. And so it certainly seems like we have a lot of headroom to grow this business.

I think it's too early for us to say exactly how big that runway is, but we are certainly early innings of unlocking that path and the fact that this is the fastest revenue grower for us in the past year and we see more runway with both the existing offerings scaling up as well as new offerings that we can put in the hands of our customers.

I think it's a great sign of the value creation opportunity ahead of us..

Thank you, Hayden..

Sure..

Thank you. One moment for the next question. And our next question will be coming from John Byun of Jefferies. Your line is open..

Hi, thank you. This is John Byun for Brent Thill. First question was, so under guidance, so Q1 you said 15% growth, full year 11.7% I think.

So obviously some deceleration through the year which you did talk about, but is there anything else that we should think about other than the lapping the price moves? I mean, to average out to by 12%, it looks like you would have to step down quite a bit by Q4. Not sure how to think about that curve. Thank you..

No. Hey, John. No, I think -- look, I think when we introduced our new kind of flat fee pricing structure back in May, and I think we talked about then that we would probably see a lapping effect in terms of growth rates in the back half of 2024, given the pacing of when that pricing change is moving through.

So that's really the major dynamic in the back half of the year. And like we said, we've kind of been touching a lot on some of the other kind of nascent new revenue streams that we've gotten going in 2023.

And I think we have kind of just a lot more work to do on execution and launching and supporting some of these additional new revenue streams, which we're confident we can kind of build and show growth in the future.

So I think overall, yes, we'll see a little bit of moderation in the back half of 2024 on a growth rate point of view, but we feel pretty confident with the combination of kind of growth vectors that we've got in our pipeline that we'll be able to produce double-digit revenue growth on an ongoing basis..

Great, thank you. And then second question was on the AI acquisition. Was that, I don't know if you can provide more color, but was that just kind of a talent, a team? I don't know if the $3 million I see on the cash was [indiscernible] balance sheet might be that, or any revenue associated with that, or just a tech talent acquisition? Thank you..

Yeah, this was really about the team and the talent. I mean, certainly we're really excited about this because Andrew and his expertise are going to be extremely meaningful in terms of accelerating our roadmap around AI machine learning. He comes from incredible leadership roles at Google and Magic Leap.

And the fact that his vision and his team's excitement to join us, given our assets, the data and our vision on future work, were really extremely exciting to us.

But this was not about revenue, it was really more about the team and our shared vision around what we're doing and I think it's going to be exciting to see what we can launch this year in the coming years given the combined efforts..

Great. Thank you very much..

Thank you. One moment for the next question. Next question will be coming from Brad Erickson of RBC Capital Markets. Your line is open..

Hi, thanks. So first, just going back to the GSV comments, you called out the modest growth for ‘24. But then obviously you've also called out to seeing some of this nice success in the performance marketing channel.

So I guess just kind of wondering why maybe not be a little bit more aggressive maybe with advertising in ‘24 or is that kind of embedded in your guidance to some degree? And then secondarily, just generally, no -- recognize you mentioned the pledge to kind of drive margin expansion from here.

So just curious if the same goes for sales and marketing intensity within the P&L going forward? Thanks..

Yeah, sure. Look, I think I'll first just say, we do not -- we don't plan to increase our brand marketing spend in 2024. And that's largely because we don't think we need to right now.

Like I said, we saw a really nice step-up increase in new active clients in the back half of the year, underneath the covers there in Q4, we have the highest new client acquisition that we've seen on the platform in two years.

And I just want to remind people that the performance marketing engine is performing extraordinarily well, and we're super pleased with optimization there. We think we can drive more growth in 2024. But 75% of our new client acquisition comes from organic or unpaid channels. So we really do have some nice tailwinds behind us on this.

And so at this point in time, we don't feel the need to reinvest in brand marketing. And all of our marketing planned expenditure is contemplated in the guidance for this year. Going forward, over the future years, we -- this marketplace business, it's a highly profitable business. We have 75% gross margins now.

I think we see opportunities over the medium term to even improve that. And I think we have the flexibility in the model to consider reinvestments in growth whether it be ongoing investments in R&D or back into brand as we go forward and still produce the growing profit margins that we've committed to.

So I feel comfortable with a lot of different scenarios there, but we're confident in growing both profit margins and pre-cash flow..

Got it. Thank you..

Thank you. One moment for the next question. Our next question will be coming from Rohit Kulkarni of Roth MKM. Your line is open..

Hey, thank you. A couple questions. First, just on this AI contributing to GSV growth, 70% growth in GSV from AI.

Maybe if you could call out any anecdotes or any emerging new use cases where you feel there is a bigger opportunity for you to do the matching around AI use cases and what can Upwork do more to tap into this new opportunity? And then second, just on the active client growth, encouraging couple quarters in a row, uptick in new clients.

Perhaps talk about the why and how sustainable is that? What are you embedding into your guidance around the near term client growth, perhaps macro tech hiring or whatnot?.

Sure, Rohit. So on your first question, just to clarify, what we saw this past quarter was our AI machine learning subcategory grew 70% year-over-year, and that was a really great result.

And it was due to, I think, what you were asking about, which was all of the investments we are making in growing this category in this area through things like our AI Services hub which we launched last year, our marketing efforts in this area where we're focused both on marketplace customers and enterprise customers who all can benefit from the talent in our ecosystem who are specialized in this area where we've been curating those talents for enterprise customers and for partners such as OpenAI through that partnership.

And so in terms of use cases, we're really seeing the full range of AI experts being called upon, whether it's for training models, whether it's for data labeling and curation.

And I think an interesting fact is that people are really looking for highly skilled experts in a variety of places to review results and outputs of models that really ensure the accuracy because there's a big quality control issue around a lot of these models, as you might imagine.

So there's a very active set of clients and talent in this space, and it continues to grow. And I don't think there's more we can do. We're just leading into this with product, marketing, talent curation, partnership. We're kind of putting all of our weapons against this to really make sure we're capitalizing on this opportunity.

Erica can probably comment on your client growth question..

Yeah, on active client growth, I think, I don't know that we feel that there's -- I would say look, the macro environment remains fluid. Our business and platform are very stable and growing. So the most recent environment of tech layoffs, I don't think we see as a big factor for us.

We’ve been -- as I've kind of articulated already, we've seen really strong momentum there. I think it's a combination of just the attractiveness of our platform, the resilience of our marketplace in this environment.

And even on the enterprise side, I think the latest spate of earnings releases really shows that people are still really, really focused on profitability. And even within that environment, we've seen nice acceleration on the land side of our business. We keep growing really nice logos with Instacart, Checkout.com, others signing up.

And so I think just the attractiveness of our offer, even within this environment, is really evident with being able to add freelancers faster, cheaper, easier than some of the competitions that's out there. So I think we're feeling good about our ability to perform in this environment..

Great, thank you. Thank you guys..

Thank you, one moment for the next question. Our next question is coming from Marvin Fong of BTIG. Your line is open..

Good evening. Thanks for squeezing me in here.

Maybe the first question, I think maybe people listening might appreciate, just kind of creating a bigger picture overview of the nice quarter, just kind of like what areas of the business, maybe from a geography or a category standpoint are doing well or perhaps are underperforming? I know you called out AI, but maybe some of your other key verticals like software programming, just curious how everything at a higher level is playing out?.

Yeah, sure. Maybe I'll take this one. I think there's really not -- there is really nothing notable on the geo front. Things have been pretty, our mix has been pretty steady and persistent, really throughout 2023 and into 2024. So not much to note there. On the category front, yeah, we've talked about AI, we're really excited about the momentum there.

Software and -- software type jobs continues to be a very, very large category for us. And maybe just, I also noted some of the bigger growers for us in one of my other answers around legal, around sales and marketing. Even logo design, we've seen some nice growth in Q4 and some of these categories in GSV.

Some of the categories that see headwinds, I think we've also talked about this. We absolutely have seen some headwinds in volume from the categories that I think people would expect in translation, writing. But these are categories that were threatened far before the advent of ChatGPT.

And in fact, even with these categories where we see some volume type headwinds, there's some really interesting dynamics underneath in which we actually see strong wage accretion in both these categories because it's really the very, very smallest kind of quickest jobs that are getting disrupted.

In fact, in the writing category, interestingly enough, in Q4, the average hours per job went up 20% year-over-year in that category. So it's a tremendously diverse platform. There's a lot going on, And I really do think we see sort of pluses and minuses across multiple categories..

That's terrific. Thanks for that, color. And maybe my other question, just I think your guidance for EBITDA margin for the year is close to 17% at the midpoint, which is not dissimilar from the fourth quarter margin performance. So just curious on what are some of the puts and takes on margin for the full year.

There's some areas of OpEx that you, I think you cited G&A, you [hold some] (ph) key roles, but any other areas you might be feeling the need to invest a little bit more or just kind of trying to understand the margin picture there. Thanks..

Yeah, sure. Yes, look, we're super, super proud of the very rapid progress we made in 2023. And on a year-over-year basis, obviously our guide contemplates both strong year-over-year revenue growth and strong margin accretion on a year-over-year basis.

I think we were really clear as we were marching through 2023 that we did intend to continue to balance margin accretion with investment and growth, and that is really what 2024 is all about.

But underlying our guidance, we really do expect really very modest year-over-year growth in total operating expenses, significantly lower than what we expect from revenue growth. And we're committed to showing that leverage over multiple years as we've been emphasizing.

Line by line, I think the dynamics will be quite similar to how we manage this year. We'll continue to invest in R&D. That line will grow the fastest. And that makes sense because of all of the kind of AI/ML team investments and really the new product pipeline that we have planned for 2024, which I think is really exciting.

Sales and marketing OpEx will be down again year-over-year, and we'll continue to optimize that area. And as we described, I think performance marketing is performing extremely well. We're going to balance investing in growth with that, with continuing to optimize.

And G&A will also be similarly managed to 2023 in that we will continue to manage that line item to show significant operating leverage on an ongoing basis. So hopefully that can clear….

No, that was terrific. Thank you very much, Erica, and thanks, Hayden..

Sure..

Thank you. One moment for the next question. Our next question is coming from Matt Burrows of Piper Sandler. Your line is open..

Thanks and congrats on the strong results. Just one for me. You had really strong free cash flow in Q4, improving profitability in 2024. I know you made the small acquisition, but it doesn't look like you executed any of your buyback.

We'd love just to hear about the thoughts around cash strategy as we move throughout the year, particularly in this kind of more stable backdrop from the macro side. Thanks..

Yeah, sure. Great question. Thanks, Matt. So, absolutely. Look, we were super pleased to get the stock buyback authorized in Q4. It's obviously a new muscle for us, it's the first one that's ever been approved for Upwork. Similarly, we're super happy to close our very first acquisition in Q4.

So we did not buy back any stock in Q4, however, we continue to believe that our stock is a great value at these levels and we do intend to execute that buyback in 2024.

At the same time, I think that we really do believe that 2024 should also present some additional opportunities for us to utilize our balance sheet and our growing cash position to identify additional tuck-in acquisitions where we can add to our growing table of talent as well as maybe capability building to continue to advance our roadmap.

So we're going to continue to be active out there and we think there are opportunities for us to utilize our balance sheet with really good ROI..

Awesome, thank you so much..

All right, thanks..
