Thanks John. Welcome to Amplitude's Q4 and full 2024 earnings call. I'm going to go through three key areas today. First, our Q4 results and the reacceleration of our business. Second, how we are going after a market opportunity, and why 2025 is the year of the platform for Amplitude? Last, product innovation, progress on winning the enterprise, and customer stories. Q4 outperformed in all key metrics. Our fourth quarter revenue was $78 million, up 9% year-over-year. Annual recurring revenue was $312 million, up $13 million from last quarter. Non-GAAP operating income was $0.2 million. Customers with more than $100,000 in ARR grew to 591, an increase of 16% year-over-year. In 2024 we exited the year with over $299 million in revenue, we grew ARR by more than 10%, and we generated almost 12 million in free cash flow for the year. Amplitude is reaccelerating. We're continuing to see progress on our strategy of win simple, win the enterprise, win the category, and win together. Customers are embracing our platform, churn is beginning to stabilize, and we see a path to accelerating our double-digit growth. I'm proud of the Amplitude team for everything they delivered in 2024. Let's look at 2025. 2025 is the year of the Amplitude platform. Every company needs data they can trust, an understanding of their customers, and ways to take action. That is exactly what Amplitude delivers. First, we help customers get trusted data into Amplitude. This is table stakes in digital analytics. Then we help companies understand what their customers are doing and why using analytics and session replay. This is what we do better than anyone else in the world. Then we enable our customers to take action based on those insights using our activation experimentation and guides and surveys products. Companies do not want standalone point solutions. Thomas and I spoke with hundreds of executives over the past year. Every single one is interested in going beyond analytics to Amplitude's platform. I want to take you through what the platform actually looks like in action. So your product manager, they use and use Amplitude analytics to discover that users are getting stuck at a certain point in the sign-up flow. You then use Amplitude’s Session Replay to identify the confusing part of the flow. You then use Amplitude’s feature experimentation to test which new sign-up flow works better. You realize your users need more help. So you add an in-product guide with Amplitude guides and surveys. All of these use cases are more powerful when used together in one integrated platform. Product innovation is the biggest driver of long-term growth at Amplitude. We're continuing to expand our platform with new products that work better together. I want to walk you through some of the highlights from 2024. We had two new products to market. In February, we re-launch Session Replay customers like Questrade and TicketSwap, use it to understand the user journey, identify issues and improve in product experiences. In October, we launched Web Experimentation. Customers like RBC Life Insurance, DoubleGood and Hard Rock Digital use it to AB test websites with a WYSIWYG editor without needing to rely on engineering. We also made major improvements to the platform. We launched enterprise grade features like data access controls and data mutability, building our lead as the enterprise digital analytics platform. We also launched Amplitude Made Easy to help users get started and see value in record tie. This led to a 40% increase in self-service sign-ups and a 40% increase in the number of new self-service users sending data. Finally, we launched Snowflake Native Amplitude in an out of the box HubSpot integration to make it easier to bring data into Amplitude. We're going to do more in 2025. Last week, we launched Guides and Surveys. We got this product to market only four months after the acquisition of Command AI. Guides and Surveys helps companies deploy in product guides, tours and surveys with just a few clicks. Amplitude's guides and surveys product provides a significantly better end user experience than the average product in market. I want to actually show you a demo of all of this now. I'm going to first start by actually showing you how terrible the average guides and surveys product is. So with the average guides and surveys product, you get tons of annoying pop-ups. As a user, your experience is now worse, not better. We call this the pop up party. Nobody wants this experience and it is not effective for product engagement. Now, I'm going to show you a demo of Amplitude's approach, because I want you to see how much better it is. Instead of showing every pop-up to every user by default, we customize what is shown based on what the user is doing in the product. So, in this demo, we can see that the user is confused. Their mouse is moving all over the screen because they don't know what to do next. We detect this confusion and then we ask them what they're trying to accomplish. They let us know and then we show them in the UI where they can complete the task. This is a tailored interaction that results in a better user experience and higher user engagement. The CEO of European email builder, Biedfried [ph], told us that the ability to guide users through their product in a personalized and data driven way was the main reason for choosing Amplitude. While it is early, we are already seeing strong demand. During launch day last week, we had a record-breaking number of new sign-ups to Amplitude. We also had some customers buying guides and surveys in Q4 before the product was even launched. A shout out to James, Vinay and the entire former Command AI team for bringing this product to market so quickly. There is a lot more on the product launch horizon this year, including some exciting AI products. We're going to be sharing more details at our Investor Day in New York on March 10. We believe our pace of innovation will continue to build Amplitude's lead as the enterprise digital analytics platform. I wanted to also share what we're doing in go-to-market to win the enterprise. The biggest change for 2025 is that we've created a new strategic enterprise accounts team to focus on our top 30 customers and top 30 prospects. This team is responsible for a significant portion of our ARR. This segment allows us to focus our resources in a more concentrated way on our larger customers. In the last year, we've nurtured stronger executive relationships, which has helped drive higher gross bookings. We now have relationships with C-level and VP levels at almost every large Amplitude customer. We've developed smarter account targeting models to help land the right customers and ensure we're building pipeline specifically in the enterprise. This paid off in a big way in 2024 and in Q4 in particular. Lastly, we built out our enterprise sales, product and professional services capacity and have fully staffed teams across the field. Our platform strategy plays a role again here. In Q4, 67% of the new land ARR in our largest targeted accounts came from multi-product deals. However, 75% of our customers still use just Amplitude product. Our data shows that those who use a product beyond analytics drive greater value, invest more into Amplitude overall and retain 10 percentage points higher than those who are analytics only. The potential expansion upside for us is big. On customers, we had a great quarter for new and expansion deals in the enterprise with RBC Insurance, Hard Rock Digital, Thrive Market, Western Union, AllTrails, Philip Morris, Calm, Bridge AI, Ultra Mobile, Mercado Libre and many more. I want to talk in detail about three of our customers today. One is Mercado Libre, the company leading the shift to online commerce in Latin America. With over 60 million buyers last quarter, including 7 million new users, they needed a way to turn their first-party data into business impact. By adopting Amplitude Analytics, Mercado Libre empowers teams to move faster, make smarter decisions and drive deeper engagement. Over 5,000 employees at Mercado Libre now actively use Amplitude with more than half going beyond dashboards to actively query user data and uncover insights. Building on this success, Mercado Libre is now expanding into experimentation and Amplitude activation, replacing multiple internal tools with our integrated platform. This shift allows them to test and optimize new features, personal campaigns and improve customer loyalty, all powered by the same data. With e-commerce in Latin America at 15% of total transactions, the opportunity is massive. We are proud to support Mercado Libre as scale driving innovation and long-term growth. We are also working with more traditional enterprise companies who are incorporating a digital experience across the customer life cycle. In Q4, we expanded our relationship with one of the world's leading automakers headquartered here in the United States. This customer is fundamentally redefining the driver experience and Amplitude is helping power, that transformation. Historically, their customer data was fragmented across multiple legacy systems by expanding their use of the Amplitude platform. They are now unifying insights across the entire driver lifecycle from in-car infotainment to dealership interactions to digital services. With Amplitude, analytics, their teams can now see how drivers engage with digital features in real time. With feature, experimentation, they are testing and refining new in-car experiences before rolling them out at scale. And with Amplitude activation, they are delivering personalized interactions that make every drive smarter and more seamless. The result is a more connective intuitive experience for drivers and a data-driven competitive advantage for the company. Lastly, we are working with the Fork, the largest online restaurant booking and discovery platform in Europe and Australia. The Fork serves over 20 million diners monthly, and over 60,000 restaurants. The Fork was looking to combine legacy vendors and point solutions into a single platform. Amplitude worked with the team to identify opportunities and workflows across analytics, session replay and experimentation, to reduce their data overhang and accelerate their ability to iterate on both their B2B and B2C applications. The Fork can now improve the onboarding process for restaurants, helping to increase subscriptions. It can help those restaurants improve the diner experience, burst, boost first and repeat bookings and drive reservation revenue. It can also identify reservation patterns and promote them across similar demographics and geographies. As a final note today, I mentioned that churn rates were stabilizing after a relatively tough 2024, a significant majority of our large COVID era customers have right sized their contracts. We are seeing signs that the worst of the churn is behind us, but we still have key accounts we need to watch. The macro environment also remains challenging. While we expect churn to keep improving, we anticipate continued pressure in the lower end of the market. Our team is focused on helping customers derive value from Amplitude as fast as possible. The best way to reduce churn is to make sure customers succeed. Before I hand it over to Andrew, I wanted to reiterate that I am proud of how the Amplitude team executed last year. We are still early in the digital analytics category, and we are set up to lead it. I'm looking forward to 2025, and beyond. Thank you for your interest in Amplitude. Now, over to Andrew to run through our Q4 and 2024 financials in more detail.
