Good afternoon, everyone. I'm James Reinhart, CEO and Co-Founder of thredUP. Thank you for joining thredUP's First Quarter 2023 Earnings Call. We are excited to share thredUP's financial results and key business highlights from our first quarter. In addition to our financial results, we will provide an update on the current conditions for resale and how the thread of customer is faring in a stubbornly challenging macro environment. Will then discuss key company-specific initiatives we're pursuing to enable sustainable profits and growth, and we'll provide an update on our Resale-as-a-Service business and remix. I will then hand it over to Sean Sobers, our Chief Financial Officer, to talk through our first quarter 2023 financials in more detail and provide our outlook for the second quarter of 2023. We'll close out today's call with a question-and-answer session. Let's begin with our Q1 results. We kicked off 2023 with a strong Q1, delivering revenue that exceeded the high end of our guidance. We achieved revenue of $75.9 million, increasing 4% year-over-year and gross profit of $51.1 million, increasing 2% year-over-year. Our consolidated gross margin was 67.3%, down from 69.1% a year ago. We attribute this to the continued growth of Remix in the more challenging promotional environment in Europe. However, we're proud to report record U.S. gross margins of 74.5%. Active Buyers and orders in Q1 remained steady quarter-over-quarter at $1.7 million and $1.5 million, respectively, with both declining slightly year-over-year. Importantly, we have seen active buyer trends improve each month of this year, and we expect buyer growth to turn positive year-over-year in Q2 and throughout the rest of 2023. We're proud to share our Q1 adjusted EBITDA of minus 8.7%, which was an improvement of over 900 basis points or $6 million year-over-year. And to put a fine point on our improving operating leverage. Our operations, product and technology costs were down by 8% year-over-year, while our revenue grew 4%. And typically on these calls, I'd like to take a moment to share our perspective on what we're seeing in the apparel landscape. For several quarters now, we based a combination of budget shoppers pulling back on discretionary purchases at the same time that retailers have been over performing with apparel and leaning into promotions to get rid of excess inventory. As a result, Resale's value proposition has been weakened by the exceptional bargain being offered for new clothing. We've been running the business under the assumption that these headwinds did not abate in the near term. But despite this backdrop, we are managing the variables that our control across our marketplace. We are leveraging our data-driven insights to optimize our unit economics. We're evolving our consumer acquisition and retention play books to drive customer growth and focusing product and technology investments in areas we believe drive margin expansion. I'd also like to spend a few moments speaking to the budget shopper specifically. A few quarters ago, we provided insights on the budget shopper from our own data, I'd like to provide an update on what we're seeing today. After pulling back on discretionary spend at the midpoint of last year, we've observed that by and large, the budget shopper has continued to fit on the sidelines into Q1, compared to the midpoint of last year, we've seen a 300 basis point decline in the number of big shoppers on thredUP. Comparatively, we've seen a 700 basis point increase in the number of upscale shoppers buying with us during that same time period. We're also continuing to see a clear bifurcation of thredUP customer purchasing behavior. With more premium shoppers leaning in and more value shoppers leaning out. Year-over-year, the average order value of our deep discount subsegment of thredUP customers declined 24% and while our upscale shoppers' average order value increased 6%. So while we are benefiting from some shoppers, trading down. We're also facing the headwinds of budget shoppers sitting out. While thredUP still offers excellent value to budget shoppers, we have been adjusting our strategies in the near term to target the non-budget segment as they are currently more engaged in the apparel market. When macro conditions improve, the retailer promotion normalize, we anticipate budget shoppers will return to our marketplace and provide a nice tailwind for growth. As I noted at the top of our call, we are beginning to see the green shoots of this budget shopper momentum with sequential improvements each month of this year. Now let me turn to the specific initiatives we're implementing to improve monetization in our marketplace and to optimize our unit economics. First, we're experimenting with a variety of levers around inventory acceptance. We've recently started testing a new fee for our Clean Out Service to improve the quality of supply in our marketplace. Initial results indicate that our bag yield of resellable items and the sell-through of items we received have both increased since an [acting] has changed. We're also selecting high-margin fees that enable us to invest in a better Clean Out service for our sellers. Importantly, we've seen no reduction in demand for our Clean Out service. And this is no small feat. Better supply, better yield, better sell-through, higher fees. Second, in conjunction with these fees, we're shaping inbound supply through seller incentives and messaging around the type of clothing we want. And when that supply is being processed at our distribution centers, we're sculpting the inventory more aggressively to list a more desirable assortment online. Third, as we branch processing of cleanout kits, while becoming more selective in our acceptance and merchandising, our bag backlog has come down, now sitting at an average of 6 weeks this as low as 1 week if you paid for our VIP services. This is the lowest our backlog has trended since before the pandemic. With a tighter backlog, we can better incentivize the right sellers, flex our fees and payouts to accelerate the right mix of goods and lower the overall tax of managing long backlogs in terms of storage, customer service and seller satisfaction. Fourth, we're shaping a new vision for customer retention and returns reduction using our data platform. It's called us thrift guarantee. And with it, we boldly envision a customer journey that aims to achieve the highest levels of customer satisfaction on thredUP. The thrift guarantee enables this by intercepting customers when they are most likely to be unhappy with their experience on thredUP, offering them easy, immediate and automated resolutions that drive them back to shop. Our first project for thrift guarantee has been centered around reshaping our returns experience with a feature called Keep-for-credit with Keep-for-credit, we're offering customers who would like to return low-priced items, the options to keep those items in exchange for shopping credit. With the keep-to-credit approach, we've seen a positive impact on customer satisfaction and repurchase rates as well as fewer cost of returns for items, whose price points don't justify the return and reprocessing cost. Across [thrift guarantee] and [keep-for-credit,] our overarching goal is to delight our customers, drive attention and improve the margin profile of our business. Early signals show these strategies have been very effective in accomplishing these goals. So to summarize, through the implementation of cleanout fees, supply shaping and thrift guarantee experiments, we are unlocking new and better ways to acquire and retain our customers while simultaneously bolstering our unit economics and positioning our business for sustainable growth. We believe that continued execution of these initiatives will result to enterprise value creation over time. Let me turn to Remix, provide an update on the progress we're making with our European resale business. It's been nearly 2 years since Remix became a part of thredUP, and we're impressed with how resilient the business has been and it's high inflation, high energy costs and the War in Ukraine. Q1 was a strong quarter for Remix. They continue to grow active buyers and net revenue year-over-year. Remix also officially launches their consignment offering in Q2 and our goal is to shift an increasing portion of the business to consign that over time. This marks the start of a long-term strategic shift for Remix that we expect to improve Remix gross margins, generate further gross profit that contribute to long-term free cash flow. All in all, we remain excited about Remix positioning to take share in the secondhand market in Europe, a market which GlobalData expects to grow to $95 billion by 2027. Now I'd like to turn your attention to our Resale-as-a-Service business, also known as RaaS, we closed out 2022 serving 42 brand clients through RaaS, and strong momentum is carried into 2023 as more retailers look to adopt more circular business models and to track and retain customers. Notably, we're seeing more global brands entering the Resale ecosystem. We recently launched new programs with American Eagle, H&M, TOMS and SoulCycle as one of the lead end-to-end Resale providers, we're thrilled to enable Resale for brands across the apparel ecosystem. We also recently announced an exciting partnership with the Container Store, where shoppers will be able to get a thredUP Clean Out Kit from any of the container stores, 97 retail locations across the country. It's exciting to venture outside of the fashion industry and work with a nontraditional retailer to extend our impact by reaching a broader swath of American consumers looking to be more sustainable. This further cements thredUP RaaS as the go-to destination for Resale apparel, and we hope to expand our client roster with more strategic partnerships like this one. As a reminder, RaaS enables the world's leading brands and retailers to offer scalable resale experiences to their customers by leveraging thredUP's marketplace infrastructure, RaaS amplifies our supply advantage, increases our sell-through and return on assets and expand our long-term profitability metrics by adding sources of recurring high-margin revenue. Next, I'd like to provide an update on our goal of reaching adjusted EBITDA breakeven. We have made significant progress each quarter since we announced our intention, and I want to reiterate our plan to achieve EBITDA breakeven on a quarterly basis and specifically in Q4 of 2023. The performance we've had in Q1 and what we're seeing in Q2 only confirms our confidence in achieving this milestone and importantly, increases our confidence in achieving free cash flow breakeven shortly thereafter. With that in mind, I want to emphasize that as a management team, we have turned more of our attention to the opportunities in front of us to grow faster and to delight more customers over time. We see a number of ways to invest in growth this year that we believe create improved free cash flow dynamics in the future. We've played good defense over the past year, and we look forward to sharing more of our offensive playbook in the quarters to come. While we remain steadfast in our progress towards profitability, we recognize that profits alone do not encompass the entirety of our mission, thredUP is a company that also has a strong sense of purpose which is evident in the impact we're making on the fashion industry in the planet. We take pride in our business and brand align ESG strategy. Today, we reaffirm commitment to balancing purpose and profit by dual listing on the long-term stock exchange or LTSE. The LTSE was designed to align businesses like ours with investors who support long-term value creation and good governance with a social and environmental conscience. Given the growth of the secondhand market, we see an opportunity for thredUP to make an outsized impact. We believe the next phase of generational enterprises will lie at the intersection of purpose and products and we are excited to be at the forefront. So let me wrap up. But before I turn it over to Sean, I want to close by restating the strength of our Q1 results despite a choppy environment out there. In particular, I want to highlight the flexibility and strength of our marketplace business model. It is precisely the fact that we run a marketplace that has allowed us to react and flex everything from the customer mix to the supply mix to our monetization. Second, as I said in our earnings from a year ago, we will continue to balance the demand for near-term scrutiny with our commitment to investing for long-term value creation. I believe we are delivering on this commitment. And while we aren't done yet, I'm immensely proud of our progress. And I want to take this opportunity to applaud the whole thredUP product team for their incredible work over the past 9 months, meeting every challenge with grit and grace. I want to give a high five to each of you for your creativity, your resilience, adaptability and the relentless pursuit of profit for the purpose. I am looking forward to what we will invent next, be offshore in a more sustainable future for fashion. It's an exciting time to be a thredUP right now, and I'm fired up about the road ahead. And with that, I will turn it over to Sean to go through our financial results and our guidance in more detail.
