Thanks, John. Good afternoon, everyone, and welcome to Amplitude's Second Quarter 2025 Earnings Call. Today, I'll cover 3 things. First, our strong Q2 results and momentum in the enterprise. Second, our platform strategy and how we are expanding through acquisition. Third, product innovation, AI developments and a spotlight on our customers. Let's start with Q2 results. Our second quarter revenue was $83.3 million, up 14% year-over-year and exceeding the high end of our guidance. Annual recurring revenue was $335 million, up 16% year-over-year and up $15 million from last quarter. We saw our highest net new ARR in 11 quarters. Non-GAAP operating loss was $1.5 million. Customers with more than $100,000 in ARR grew to 634, an increase of 16% year-over-year. In addition to these results, our multiproduct attach rates continue to grow as customers choose Amplitude as their end-to-end platform. 67% of ARR now comes from multiproduct customers, up from 64% last quarter. 2025 is the year of the platform. Every company needs 3 things: trusted data on their customers, insights on that data and ways to take action on those insights. Amplitude delivers all 3 in a single platform. In Q2, we saw dozens of new enterprise customers come on board and many existing customers expand their Amplitude footprint. We also saw more traction with marketing teams after announcing a new suite of marketing capabilities in May. We continue to win against legacy vendors and point solutions as companies look to simplify their tech stacks. This is what drove a record level of multiproduct ARR. We've been deliberately focusing on the enterprise and the progress this quarter is the result of that work. Many of the deals we closed this quarter were years in the making and required multiple steps, including hiring the right reps, building the right named account strategy, finding the right solution fit, instrumenting value, closing the deal and driving impact for customers. Let's shift to product innovation. I have spent a lot of time transforming the Amplitude team to become AI native. Back in June, we ran a week of AI training for the product development team. Then in July, we hosted a week-long hackathon focused on building AI products. I'm going to demo some of the outputs from this shortly. We are also leveraging M&A to become AI native and expand the platform and our acquisition of Command AI late last year is a great example. We acquired the company in October of 2024, launched Guides and Surveys 4 months later. And today, it has the fastest adoption curve of any product in Amplitude's history. Command AI had a mature product backed by an exceptional team. Many individuals from that team are now leading our efforts on AI agents and other AI products. We continue to use M&A and talent acquisitions to expand our platform and bring great talent into Amplitude. Over the past 2 months, we've added 3 exceptional teams. First, we acquired Kraftful, an AI native voice of the customer start-up turning unstructured feedback such as support tickets, app reviews and customer calls into actionable insights. I've admired Yana and Kraftful for years, and I'm excited I get the opportunity to work with her and the Kraftful team to give customers a complete view of the user experience. Kraftful works with tens of thousands of product builders and many Amplitude customers have been asking for voice of the customer insights. We're integrating Kraftful's proprietary AI analysis into our platform. Second, we acquired the Inari team, an AI start-up focused on surfacing insights from unstructured data using LLMs. The founders, Frank Lee and Eric Kim bring deep expertise in applied AI. They have joined our AI agents team and are already working to accelerate our road map, which I'll demo for you shortly. Finally, we acquired the founders of June, a startup that built a distinct product, brand and a thriving community around simplifying product analytics. Two years ago, they created the first product analytics tool to integrate LLMs for generating insights in natural language. The founders, Enzo Avigo and Ferruccio Balestreri bring a product-first philosophy that inspired our thinking for Amplitude Made Easy last year. Now that we're working together, we're excited to leverage their expertise to simplify digital analytics while developing the next generation of agent-driven experiences. Now let me share with you what we're building. On June 10, we announced the beta program for Amplitude's AI agents. With our agents, what once took teams weeks can now take 1 person minutes. That changes how product, marketing and data teams build, ship and learn. LLMs allow AI agents to quickly combine taxonomy data, watch thousands of Session Replays, generate insights and then make suggestions for product changes on your behalf. That makes them great product analysts. The potential benefits of agents are huge. As an example, it normally takes Amplitude about a month to optimize a website conversion workflow from idea generation and experimentation to engineering and launch. With an Amplitude AI agent, the same workflow now takes less than 1 day. I want to show you Amplitude AI agents in action with a demo. When we launch later this year, our customers will be able to leverage ready-to-use templates focused on popular use cases like optimizing conversion flows and analyzing Session Replays. The first agent I want to show you is focused on optimizing website conversions. I'm going to select an event for the agent to optimize. I'm going to choose CTA clicked and then create the agent. The agent will then think and come up with a plan on improving CTAs clicked. As part of this, the agent is identifying which pages are highly correlated with CTA's clicks and is then presenting them as different options. Gone ahead and selected the pricing page since it's one of our highest converting pages. The agent is now analyzing recent events and Session Replays tied to the pricing page. The agent has identified that buyers are running into dead clicks while interacting with pricing plan headers. The agent takes that learning, contextualize it with Amplitude events and best practices and brainstorms 3 new strategies for immediate review. One of the strategies the agent recommends is making the pricing plan headers animated and clickable based on the Session Replay learning. So let's go ahead and explore that strategy. The agent is creating new variants based on this strategy and is now live generating code for potential strategies we can preview in our experiment visual editor. Let me go ahead and take a look at this first variant here. In this, the agent added a hover effect to the pricing plan sections and made them clickable, which optimizes for CTAs clicked. I can review, edit and approve this variant before deploying a new experiment. To summarize, our agent identified issues with pricing page conversion, recommended a strategy for solving it and then created a new page that improves the experience. In addition, we're also building agents that focus on insights. These are always-on analysts that perform hundreds of analyses and automatically surface insights with minimal human work. To do this, let's go ahead and create a dashboard monitoring agent. With the dashboard monitoring agent, customers can select a few dashboards they've created on Amplitude and have the agent surface top themes on a weekly basis and then run root cause analysis that explains major changes. I've created the agent and analyzes every chart across each dashboard that I've assigned to it and then surfaces the top insights. In one of these takeaways, if you look at the second one here on the page, the agent identified 71% of testers create agents, 60% generate strategies and new variants, while only 6% have directly deployed an action. With the dashboard agent, customers have unlimited resources to monitor analytics. This saves analysts tons of times and uncovers lots of insights they wouldn't have found otherwise. Since our announcement in June, we have received a huge amount of customer interest. Customers in the beta have been blown away by what our agents can do. On an onboarding call, the product analytics lead at Hostinger stopped us mid-demo and said, this actually runs an experiment, wow, that is amazing. The co-founder of ResMed called our Session Replay agent a home run, and the product owner at Global Radio said his team was already meeting about how to put our agents' recommendations into action. We believe Amplitude is the only company in digital analytics doing anything meaningful with AI today. We have the most complete digital analytics platform, and we are out executing everyone else with elite talent. I want to show you one more example. We are also helping companies with AI transformation in other ways. Companies want to know how they rank on LLMs. So we're building LLM brand analytics to answer this question. I'm going to show you a demo of how this works. With Amplitude, customers will be able to quickly understand how AI is talking about their brand. They can understand the types of queries and prompts that lead to being mentioned by LLMs. If you look here, the bar on the right indicates what percentage of queries Amplitude shows up in. Here, we can see that we rank well in behavioral analytics and digital product analytics and go deeper by looking at more specific prompts. Let's take a look at analytics for marketers. You can see what percentage of the time we show up for each prompt and what our rank is in the prompt on the right. For example, when prompting for alternatives for Google Analytics for advanced marketing insights, Amplitude shows up 100% of the time with an average rank of 4.2. We also get the exact ranking per model in this drop-down. For example, we ranked #8 in GPT-4.1 mini and #2 in Gemini 2.5 Flashlight. Customers can also track mentions across various LLM platforms and focus their attention across different models. We can see here that Amplitude ranks quite well with Claude, but we have opportunities for improvement with ChatGPT. We are going to continue to aggressively innovate. This has been a breakout quarter with industry analysts. Last week, the 2025 Forrester Wave for Digital Analytics Solutions was published for the first time. Of the 10 vendors evaluated, Amplitude was named both a leader and a customer favorite. We received the highest current offering score of any vendor in the report and the highest score possible across 21 criteria. The Forrester report showed that Amplitude is ideal for product-led organizations where product and marketing teams need close alignment and ease of use as a priority. It also recognized our Agentic AI capabilities, intuitive interface and compelling road map. Most importantly, the Forrester evaluation showed that customers praise Amplitude's collaborative partner-like approach. We are not just a better analytics tool. We're invested in our customers' long-term success. This is a testament to our platform strategy and the momentum we're seeing as a business. Amplitude also ranked #1 in 8 categories in G2's Summer 2025 report, including the top spot in product analytics for the 20th quarter in a row. This recognition positions Amplitude as a clear market leader, setting us apart from legacy vendors and point solutions. We had a great quarter for new and expansion deals with enterprise customers, including Microsoft, Twilio, Redis, Telenor Denmark, Viator, Chess.com, GoFundMe, Landmark Group and MUSINSA. I'm going to highlight a few. Viator, a tripadvisor company for booking travel experiences, partnered with Amplitude to accelerate product innovation and foster a culture of data-driven decision- making. With Amplitude, Viator has increased its speed to insight and pace of experimentation. Amplitude's self-service analytics has enabled the Viator team to quickly optimize experience, surface bugs faster and improve interface performance, unlocking a 15x ROI in just 1 year. Now Viator is expanding with Session Replay, combining behavioral data with visual context to further reduce friction in the traveler journey. With the Amplitude platform at its center, Viator is building faster, smarter and more personalized experiences to help travelers around the world plan unforgettable trips. Telenor Denmark, part of one of the Nordic's largest telecom groups, turned to Amplitude to power a full transformation of its marketing analytics stack. Replacing a legacy tool set, Telenor chose Amplitude for the unified platform approach and the ability to blend both web analytics with activation capabilities. Telenor's investment in Amplitude is part of its long-term vision to consolidate analytics, experimentation and activation within a single ecosystem. Centered on behavioral analytics and the capability to scale, Telenor is working on modernizing its marketing ecosystem to drive greater personalization. Lastly, we are now working with a leading North American title insurance provider as they transform how digital products are built for consumers and brokers, facing a patchwork of disparate tools and siloed teams, they turn to Amplitude to help unify their approach. Today, they're using Analytics, Experiment, Guides and Surveys and section replay to give product teams shared visibility and control. By consolidating onto the Amplitude platform, they can now analyze behavior, test improvements and drive revenue through better usability, accelerating innovation within a traditionally slow-moving industry. Q2 was a strong quarter for Amplitude. It reflects our years of work refocusing the company on the enterprise and on our strategy to expand the platform. We believe our most recent efforts to re-architect Amplitude to be AI native will accelerate the strategy and drive success in the years ahead. While I'm proud of the team's achievements, we are just at the start. We are still early in our opportunity, and we will continue to execute against the plan we've laid out. I'd now like to turn it over to Andrew to walk you through the financials.
