Thanks Yao, and good afternoon, everyone. Welcome to our 2024 first quarter earnings call. I'm going to focus on three topics today. Q2 financial results and what we're seeing, how we're going after our market opportunity, and continued product innovation and customer stories. I'm pleased to report that we beat across all guided metrics this quarter. Our second quarter revenue was $73.3 million, up 8% year-over-year. Annual recurring revenue was $290 million, up $5 million from the end of the first quarter. We now have more than 3,200 paying customers. In Q2, customers representing $100,000 or more of ARR, grew to 547, an increase of 10% year-over-year. We are operating responsibly and have generated $5.7 million of free cash flow year-to-date. Before we get into the quarter's details, I want to call out that we are revising our annual guidance lower on non-GAAP operating profit for the year while raising revenue. This is due to a change in Russian sanctions announced in June. Without this, operating profit guidance would have been unchanged. We'll go into more detail shortly. Our top priority at Amplitude is reaccelerating growth, we are making great progress. New business remained healthy in the second quarter. Amplitude's value proposition continues to resonate and our win rates are strong. In spite of tight IT budgets, companies are investing in digital experiences. I would characterize the macro environment as stable quarter-to-quarter. We continue to feel great about our competitive position, particularly against point solutions and legacy players. We have a differentiated platform approach. Customers find value quickly and privacy regulations are helping to drive incremental demand. As expected, churn also remained high in the second quarter. This was driven by some of our most severe legacy contract resets, which we have been highlighting for several quarters. We are optimistic that the significant majority of overbought to optimization contracts of this nature are now in our rearview mirror. We are building momentum from the many improvements we've made in go-to-market. Amplitude Plus, our self-serve offering continues to gain momentum with customers of all sizes and types. Plus performance was strong in Q2. New onboarding improvements and a simplified data setup process are driving uplifts and activation. Plus also continues to serve as a valuable feedback loop informing our win simple approach on core Amplitude. Our named account approach, led to higher quality deals in Q2 than in prior quarters. We also saw better platform attach rates and steady improvement in enterprise land ASPs. Improved account management is letting us better align with customer initiatives and land larger customer engagements from the start. We are growing our ability to gain mind share and budget across product, marketing and data buyers. The customer expansions we are unlocking are also of higher quality. During the start of the pandemic, data volume increases drove many of our largest expansions. Today, customers are expanding because Amplitude is viewed as the right future-proof enterprise-ready platform in a world where companies win and lose based on their digital experience. I'm also very encouraged by the continued green shoots that we called out in prior quarters. Customer relationships are healthier post-renewal with customers using more of our platform and attaching services. We are more aligned with our customers' current growth ambitions than we have been in the last year. In our top 100 customers, underlying utilization trends continue to improve quarter-to-quarter. Cohort health is visibly improving. For customers who have optimized with us one-time a majority of the associated ARR, either renews flat or grows off of that base. For customers acquired in the second half of 2022 and later, gross and net retention patterns continue to show better dynamics than those from 2020 and 2021. Pipeline signals also are encouraging for the second half of the year and into 2025, thanks to coordinated efforts across marketing, sales and partnerships. We are seeing particular strength in our U.S. enterprise business. International markets, while behind the United States in terms of maturity are demonstrating the same level of latent demand. Average deal size in our second half pipeline is up by 25% year-on-year. And we're seeing a significant increase in large deal opportunities. Now let's address the item that accounts for the change in non-GAAP operating profit outlook. In April 2022, we stopped all new sales activity in Russia and Belarus. We also terminated all contracts with customers that we knew to be targeted by U.S. sections. Russian government-owned, Russian oligarchs-owned or Russian government-controlled news outlets we continue to serve customers who did not meet that, criteria. On June 12, the U.S. Department of the Treasury increased the scope of sanctions in Russia, leaving us unable to serve any customers in Russia and highly unlikely to be able to collect from these previously unaffected customers. If not for this isolated insulin, our outlook on operating profit for the year would have been unchanged. While this ways and what would have been a much stronger Q3 and exit growth rate, I would like to draw focus to the bigger picture. We are raising revenue guidance for the year despite facing a material headwind in Q3. The business improvements we have put in place are starting to deliver results. We believe ARR and revenue reacceleration are both well within our reach. We expect to be free cash flow positive for the year. We continue to invest behind the biggest driver of long-term growth for Amplitude, product innovation. Next slide, please. Our thesis is that analytics is a center of gravity for any workflow that touches customer and product data. Without analytics, the rest of the stack is much less useful. Session replay is making rapid progress in its second live quarter. There is a lot of customer pain experience from fragmented tooling. Our platform is continuing to displace point solutions, aid in renewal discussions and offer a shorter time to value for our platform. We expect a larger unlock when we launch mobile session replay later this year. Experiment and CDP landed with marquee customers and some of our largest expansions this quarter were catalyzed by our non-analytics offerings. A confluence of tight customer budgets, enhanced product maturity and improving field enablement are letting us lean in. Today, 21% of our annual contracted customers use more than one product, up from 15% at the same time last year. Customers who use more products retain better. Industry analysts are also recognizing our leadership. Amplitude was named as the only leader in the latest Forrester Wave for feature management and experimentation. We achieved the highest possible scores across 11 criteria, with particular call-outs for our platform breadth, depth, user interface, pricing and vision. We announced the general availability of Amplitude Snowflake native offering in June. Our warehouse native approach is all about extending what has made Amplitude successful, being one of the most open, agnostic and trusted ways to access and find insights from customer data. Early interest here is encouraging. We've made other huge strides in our mission to win the enterprise. Large sophisticated enterprises have different needs, and one of their top requests is for enterprise-grade controls. That's why I'm excited to announce enterprise-grade data access controls and data mutability. These advancements help to eliminate data drift, ensure compliance and reduce friction around managing data privacy. With our enterprise-grade digital analytics platform, customers can keep data in sync with their data warehouse confidently control who sees what. With improved security, scalability and privacy, we're confident we can convert the most conservative chief data officers into Amplitude Champions. Last quarter, I talked about radical simplicity. We've always been a self-serve platform, but now we want to eliminate the learning curve altogether. This is one of the most ambitious projects we've taken on as a company. We've reimagined our product experience from top to bottom, and we will be launching ran new Amplitude on September 10. We're offering users a single line of code to get up and running default dashboards out of the box, auto capture and visual tagging, bundling of session replay and experiment SDKs with analytics out of the box, new navigation and user interface in a new conversational version of our AI assistant and search. Analytics today is hard. We are going to make it easy. All the priceless customer behavior, product and community knowledge embodied an Amplitude will be approachable to everyone. It will be radically easier to get started, get insights and get value. We want Amplitude to be a daily habit and our new platform will help get us there. We can't wait to share more. Turning to customers. In Q2, we landed and grew with HubSpot, Fanatics Live, Cloudflare, SketchUp, Writer, Character AI, Volvo, Icelandair, Cook Children's Healthcare System and Farmers Business Network. A notable highlight this quarter is SketchUp, a business unit of Trimble. Globally, they are one of the largest 3D modeling tools in the construction and industrial industry with tens of millions of monthly users. With this renewal, product and data teams are drastically increasing the amount of data from their web and mobile applications in addition to going live with Amplitude CDP. SketchUp aims to democratize data across the business, empowering product managers with self-service insights. With Amplitude, SketchUp will be able to enact PLG best practices, everything from encouraging free-to-paid upgrades, keeping users engaged after the initial learning curve and identifying churn as it happens. We're excited to support SketchUp in their ongoing data-centric transformation and look forward to contributing to their continued success. We also had a win with Cook Children's Health Care System, one of the largest non-profit pediatric medical centers in the US. They are migrating from Google due to data privacy and HIPAA compliance concerns. With a focus on digital transformation and optimizing the patient experience, they chose Amplitude to power user insights with their newly launched web experience. Amplitude will let them connect web and mobile patient journeys to increase patient appointment conversion and identify channel performance across marketing campaigns. Character AI has been an Amplitude customer for less than a year and is already expanding its use cases and adoption of Amplitude. They are one of the fastest-growing AI companies, empowering users to create and interact with various AI characters that feel alive. Amplitude has proven critical in tracking their users' onboarding flow and the success of new feature releases. This is especially important as they roll out their new voice feature, which allows users to hear characters speaking to them in one-to-one chats. They are consolidating their analytics efforts by adding our whole suite to this renewal. Another great win this quarter is with a Global Job search platform, which saw the potential to consolidate multiple point solutions and for Amplitude to become their single source of truth. Before Amplitude, the team couldn't trust the results of the experiments they would run. They spend more time arguing than running tests. By moving away from Optimizely onto Amplitude, they could finally scale their experimentation program by eliminating two big blockers, a lack of data trust and the painful overhead associated with integrations and data pipelines. This is a great example of how our Amplitude approach solves pain with unbeatable value. With our digital analytics platform, Amplitude is able to bring together product leaders, data scientists, engineers and growth teams to make data-driven decisions, streamline workflows and connect insights to actions at scale. Before I turn the call over, I want to thank Mike Dean for his contributions during this period of transition at Amplitude. He is one of the rock stars at this company and has done an amazing job rising to this occasion at an important time for Amplitude as interim finance leader. I'm excited to introduce our new Chief Financial Officer, Andrew Casey. Andrew has more than 25 years of battle-tested enterprise software experience. He has had senior finance roles across ServiceNow, Oracle and HP. More recently, he took walk me public in his IPO and was CFO of Lacework. I've gotten to know Andrew well recently. He's a fantastic combination of strategic thinking while being able to get into the details operationally. He also has a genuine passion for the space we're in. We're both in it for the long-term, and I'm looking forward to working closely with him as we write the next chapter of growth for Amplitude. We have been up-leveling every area of our business and building momentum. We continue to see more pockets of strength and weakness. We will turn our green shoots into something more as we build a defining generational software company. Thank you for your interest in Amplitude. I'd now like to turn it over to Andrew for a brief introduction before Mike walks you through the financial results.
