hank you, Chuck, and welcome, everyone. Today, I'll share our Q3 2025 results and the key trends driving our performance. I'll then dive into what we launched at INBOUND, where we are seeing AI momentum and how we are reimagining marketing for the AI era. I'll wrap with our growth formula and how both our current and emerging levers create a durable path to growth. Let's dive in. Q3 was another strong quarter for HubSpot. Revenue grew 18.4% year-over-year in constant currency, reaching $810 million. We delivered solid operating leverage with an operating margin of 20%, reflecting our ability to balance growth and profitability. Total customers increased by 10,900 in the quarter, bringing our global customer base to nearly 279,000. Our results were powered by 3 drivers that continue to show up quarter after quarter, platform consolidation, multi-hub adoption and upmarket momentum. These themes are consistent, compounding and reinforce the strength of HubSpot as we scale. HubSpot is winning as a truly unified customer platform. Companies are consolidating their go-to-market stacks on HubSpot to reduce total cost of ownership, gain a unified view of their customers and accelerate AI innovation. Multi-hub adoption has become the norm across both new and existing customers. 43% of Pro Plus installed base by ARR now subscribe to our 3 core hubs, up 4 points year-over-year and 39% own 4 or more hubs, up 6 points. This expansion shows the value customers see in growing with HubSpot, and it is clear proof that our platform-first strategy is working. Our upmarket segment is humming. Larger companies are choosing HubSpot for its power, sophistication and speed to value. Deals over 5,000 monthly recurring revenue grew 35% year-over-year, reflecting the payoff from years of product investment, strong partner alignment and rising brand awareness amongst upmarket decision-makers. A great example is QS, a global education services company with over 1,000 employees. They replaced a 20-year-old legacy CRM and chose HubSpot to power their AI-first transformation, citing our AI strategy, approach to agents and pace of product innovation as key reasons for signing a multiyear multi-hub agreement. AI innovation took center stage this quarter. The highlight was, of course, our annual INBOUND conference. It was great to bring together 13,000 people in person and another 550,000 online from across our ecosystem. We launched more than 200 new updates and products that were well received by our customers and partners. The energy and feedback from INBOUND reinforce that our AI strategy is resonating and customers see HubSpot as the platform to help them grow and win with AI. Our strategy is simple: embed AI into hubs our customers use every day, build agents that do work and create breeze assistant and connectors that turn data into insights. At INBOUND, we launched new features in every hub from AEO strategy tools in Content Hub to AI-powered e-mail in Marketing Hub and AI meeting assistant in Sales Hub. We introduced Data Hub, which helps customers bring their data together in one place to get more value from AI. We enhanced our featured agents, customer agents and prospecting agent, launched a new data agent and opened up Breeze Studio, so customers can build and customize their own agents. And we became the first CRM to connect directly with the 3 leading LLMs, ChatGPT, Cloud and Gemini. These innovations are delivering real results for customers. Customers who use our embedded AI features in Marketing Hub get better results, higher click-through rates and over 50% higher lead conversion. Similarly, customers who use AI features in Sales Hub are winning almost 10% more deals. Our agents are also gaining strong adoption. Customer agent now has over 6,200 customers, up 48% from last quarter with an average resolution rate in the 60s. Prospecting agents has been activated by 6,400 customers, up 94% from last quarter, and customers have used it to engage over 1 million prospects. Data Agent is new, but already has 1,700 customers who have activated it. Breeze Assistant is the digital assistant for every go-to-market employee, and we have seen weekly active usage increase by 56% in the past 6 months as customers use it to summarize records and uncover insights that drive performance. A key part of our AI strategy is our LLM connector approach, and the momentum we are seeing here is impressive. Our ChatGPT connector has been activated by more than 47,000 customers with 55% of them being Pro Plus customers, and our Cloud Connector is already being used by over 6,000 customers. We believe that LLMs and HubSpot are powerful together and complement each other. Why? Well, there are 3 reasons. First, LLMs create insights. HubSpot provides the context that makes insights possible for go-to-market teams. LLMs are great at generating ideas from public data or a user prompt. But HubSpot is where the full go-to-market context lives, every interaction, sales conversation, support ticket, marketing campaign. That context is necessary to turn generic AI output into insights that are accurate, relevant and actionable. Second, LLMs generate ideas. HubSpot turns them into action within a business context. On their own, LLMs can tell you what to do. With HubSpot, you can actually do it. HubSpot is where companies build sophisticated workflows, launch multichannel campaigns and take actions to drive growth. And third, LLMs are great at single-player tasks, and HubSpot is built for multiplayer teams. HubSpot remembers each user, their role, preferences, team, what they have permissions to access and where they can take action. Now stepping back, HubSpot houses AI and is the customer platform where intelligence and context are applied, acted on and shared across teams. Platforms were sticky pre-AI, they will be even stickier in the AI era. Okay. Let's talk about how we are reimagining marketing for the AI era and the opportunity it creates for HubSpot. Marketing landscape is changing fast. Search traffic is declining globally as AI overviews provide answers. Customers are spreading their attention across channels and visiting fewer websites. At the same time, AI is creating entirely new opportunities via LLMs like Answer Engine Optimization, or AEO. At HubSpot, we saw these shifts coming early. We've been diversifying marketing channels and experimenting with AEO, and that strategy is working. At INBOUND, we introduced the Loop, our new playbook for growth in the AI era. It gives customers clear step-by-step guidance on how to drive growth by combining human creativity with AI efficiency. And the response has been incredibly strong with 270 million impressions on Loop content and over 100,000 views of the Loop playbook experience. We also launched new products to help customers put the loop into action, including Data Hub, which makes it easy to build ideal customer profiles and Marketing Studio, which helps marketers personalize content based on buyer intent. A key part of the loop is helping customers show up in AI-generated answers. Our AEO grader and AEO strategy tools launched at INBOUND make it easy for businesses to come up with a strategy and improve their visibility in LLMs. And last week, we announced an agreement to acquire XFunnel, one of the first and most complete platforms for tracking and improving how brands appear across LLMs. XFunnel shows when and how often your brand is mentioned in AI-generated answers and provides clear guidance on how to strengthen that presence. We'll natively build XFunnel into HubSpot, giving our customers even more ways to understand, improve and grow their brand visibility in the AI era. Now let's talk about our growth formula and how we are unlocking new levers for HubSpot. Our core growth levers continue to perform, platform consolidation, multi-hub adoption and upmarket traction. At the same time, emerging levers are gaining momentum, including seats pricing change, core seats and credits. We introduced the core seat last year to give customers edit access to the Smart CRM, the unified record that powers our platform, and that strategy is working. At INBOUND, we made the core seat even more valuable by adding AI and data capabilities like Breeze Assistant, Smart starts, projects and enrichment data and by unbundling the Smart CRM so customers can start right there. Our vision is to make the core seat essential with AI and data value for every go-to-market employee. Credits are another powerful emerging lever. They are our universal usage-based pricing system, covering AI agent actions and data hub sinks and soon will extend across the entire platform. Credits tie our growth directly to customer value. And as customers use more data, use more AI and automation inside HubSpot, they'll grow with us. Together, core seats and credits expand how HubSpot captures value, building on our durable foundation and creating a long runway for growth. As I wrap up, I want to share our conviction that HubSpot is positioned to lead in the AI era and drive durable long-term growth. We are innovating rapidly, transforming into an agentic customer platform and operating efficiently at AI speed. We have durable differentiators and growth levers, and we deeply understand our segment and what small and medium businesses need to grow with AI. We are uncovering new ways to drive efficiency and finding signals to show our customers what's possible with AI. I'm more confident than ever in our strategy and our ability to deliver value for customers in this new era. Thank you to all our customers, partners and shareholders for your continued support. And a huge thank you to all HubSpoters around the world for staying focused on solving for our customers every single day. With that, I'll turn the call over to Kate to take you through our Q3 financial results in more detail. Kate?
