Thank you, Yao. Good afternoon everyone, and welcome to our Q1 2023 earnings call. We have a lot to cover today, so I'm going to focus my remarks on three key areas. First, our Q1 financials and some customer product and AI highlights; second, an update on the environment and outlook for 2023; third, how we're adapting and why the long-term opportunity remains as compelling as ever. Before I get to that, I want to reiterate my view on the market. Almost every business with a digital product needs to know more about what their customers love, what causes them to get stuck and what keeps them coming back. Product led growth will become a more important channel for any business with a digital footprint. This means we have an opportunity to help our existing customers to expand to multiple different departments within those customers and to dramatically extend our reach to new companies of all sizes. The demand for digital analytics remains strong and we're only just scratching the surface of the opportunity. Turning our attention to Q1 results, our first quarter revenue was $66.5 million, reflecting 25% year-over-year growth. Our dollar based net retention rate was 106% with trailing 12 month NRR of 114%. Our operating loss was $7.9 million, or negative 12% of revenue, and our total customer count increased to 2,175. The first quarter saw us win new customers from multiple industries including PGA of America, Panda Restaurant Group, Viator, RudderStack, and Endeavor, home to brands such as IMG and UFC. We expanded with companies including Chick-fil-A, Chess.com and AMC Networks. We also brought in substantial deals with some of the world's largest on-demand music services and streaming entertainment companies. Let me share more details on two of those deals. Panda Restaurant Group, which operates over 2,400 Panda Express locations, selected Amplitude Analytics to gain real-time insights that were previously unavailable with their existing tech stack and related dashboards. Our self-service capabilities, quality of insights, and scalable platform will enable the Panda team to become more sophisticated in their data-driven decision making. Panda will leverage Amplitude to power their new rewards program. By understanding how rewards, coupons and promotions directly impact customer behavior, the Panda team can make informed decisions that will keep their guests coming back. RudderStack, a customer data platform powering over 30,000 apps and websites, is a great example of a company purchasing both Amplitude Analytics and experiment at inception. RudderStack was previously using a hodgepodge of point solutions, which meant that running even very basic A/B tests was time consuming. Now the RudderStack team can use Amplitude to run experiments and analyze the results all in one platform. This makes it much easier for its product, sales and customer success teams to access customer data, identify pain points, and deliver a better product experience. We are relentless about improving the Amplitude product experience. In Q1, we redesigned our chart creation flow and layouts reducing the time it takes to create your first chart. Early feedback has been tremendously positive with signs of increased feature conversion and retention. We want everyone to reach their first aha moment much quicker whether you're trying to craft patterns between offline buyers and online sellers, design promotions for a loyalty program or find hidden signals between point of sale systems, deliveries and reservations. Recent advances in artificial intelligence have the potential to greatly accelerate the growth of our category. Developments in generative AI enable users to navigate complex workflows with simple natural language interfaces. For a platform as powerful as Amplitude, this can transform both the time to value and the base of users we speak to. We think such interfaces can let every user answer questions and service and surface insights in a self-service manner. We’ve also seen the ability for these models to intelligently classify and summarize information dramatically reducing the barrier for customers to reach a clean instrumentation. We also have the world’s most comprehensive dataset on product and customer behavior, which allows us to develop powerful foundational models that would have significant impact on how companies develop digital products. We are hard at work experimenting with new ways to leverage this powerful data set for our customers, and I look forward to sharing more with you all in the future. As we made our way through the first quarter, it became clear that our operating plan needed to change. It is a reset year for a lot of our customers. The overall business environment was far more challenging in Q1 in comparison to Q4. The tech in SMB sectors have been hit especially hard with more tech employees laid off in Q1 than all of 2022 and buyer behavior is more cautious as a result. Volume-based pricing also means a more severe right-sizing for us after a period of acceleration. In addition, our exposure to more challenged end markets was having a greater impact than we expected. When customers spending cuts were more surgical last year, Amplitude fared relatively well. However, it’s now apparent that companies are reducing budgets more indiscriminately as the demand for their own offerings softens. As a result of these dynamics, we are updating our full year guidance. We now expect 12% to 13% revenue growth for full year 2023 down from the 19% to 22% growth we previously guided to. Against this, we are being very deliberate about how we operate our business at its current scale and accelerating our profitability and free cash flow. Chris will take you through the details shortly. In an environment as fluid as this, we operate by focusing on what we can control. We took the difficult decision in early April to reduce the size of the Amplitude team by 13%. The move focused primarily on the go-to-market organization, but also covered product development and G&A. To successfully capture the opportunity ahead of us, we need to continue evolving as a company. That’s why I have been deliberately improving the operational maturity of the business. I’m very excited about the executive leaders we’ve brought in over the past year, including Thomas, Chris, KJ, and others. They are transforming their teams today and driving strategy and execution for the future to lead Amplitude to $1 billion in revenue and beyond. I previously talked about building blocks of better execution around scalable pipeline generation, sales operating cadence, enablement and value-based selling, improvements here are starting to deliver tangible results. Pipeline has been a bright spot. Our win rates are up against the competition. We’re keeping the aggressive pace of product innovation that Amplitude is known for. We remain disciplined in our investment approach and we continue to raise the bar for execution across the Board. As the markets continue to change, it is crucial that we adapt. Here is how we are doing that. First, the April restructure means that we have a much clearer path towards operating as a profitable free cash flow generating business. We’ll operate responsibly against a short-term lowered growth outlook while still leaning into the opportunities ahead. Second, we have a more defined approach to account ownership and engagement in our go-to-market organization. We wanted to reduce the diffusion of responsibility and drive more accountability and the changes enable us to approach our customers differently depending on their needs and industries. Third, our product development team will intensify its focus on the huge opportunity in the enterprise space. Many companies need more help in getting started and then driving digital maturity. Our efforts on ease of use and verticalization are specifically targeted to win this group. Last, we’re doubling down on our product like growth efforts. We are in the first phase delivering for smaller customers making sure that unhappy Google Analytics users have an easy natural migration path to Amplitude. Phase 2 will be targeted at smaller teams and larger accounts. We welcomed industry veteran Nate Crook to Amplitude as our new CRO in April. Nate has over 20 years of enterprise software sales and engineering experience. He spent eight years at Microsoft and led their worldwide sales and strategic partnerships team. He’s also held sales leadership goals at Cisco, Symantec, and a number of other startups. Together, these developments will enable us to speak to many more prospects that we do today in a much more effective and scalable fashion. Against what is a challenging message? I want to take a step back. The market opportunity for Amplitude is incredibly compelling. The digital analytics category remains in its early days. We are underpenetrated within our customer base. This is especially apparent when we look at how our most sophisticated customers use Amplitude versus the average. We are continuing to take share from Google Analytics displacement and consolidating numerous weaker point solution in fragmented end markets. Amplitude’s value proposition is unique and we are best positioned to win in this market. We offer the most powerful digital analytics solution at the greatest value, trying to replicate what we offer out of the box by using legacy tooling involves a combination of data scientists, expensive add-ons, and lengthy implementations. Amplitude’s deep understanding and focus on the product persona and workflows will continue to set us apart from the pack. No other digital analytics platform can provide the self-service data insights and actions that we can. At Amplitude, we have succeeded by doing what is right for our customers in the long-term. The growth we’ve experienced over recent years has been in tandem with the health and ambitions of our customers. This means more pain in the short-term has many of these businesses face cyclically slowing growth? Here is the message I’d like to leave you with. It is a reset year for many of our customers. The macro headwinds are temporary and we see more validation of our approach in immense TAM every day. Over the long-term, I expect we will accelerate our growth. There remains a lot of opportunity for us to improve our operational maturity and execution, and all of these are controllable and fixable. Our team is rising to the occasion. We are well set up to navigate this environment. We have accelerated our path to profitability, free cash flow, yet again even against the reduced growth outlook. I’d now like to turn it over to Chris to walk through the financial results. Chris, welcome to Amplitude.
