Thank you Ryan and welcome everyone to the call. I'll start by discussing our Q3 2024 results and the key trends driving our momentum. Then I'll give an update on the product launches at Inbound and the feedback from our customers. I'll wrap by highlighting how we are setting ourselves apart as a leading customer platform for scaling companies. Let's dive in. Q3 was another strong quarter for HubSpot, with revenue growing 20% year-over-year in constant currency. We delivered another quarter of significant operating margin growth with over 200 basis points of margin expansion year-over-year, driving our operating margin to 19%. Total customers grew to 238,000 customers globally, driven by 10,000 net customer additions in the quarter. I am thrilled to see customers continuing to consolidate on HubSpot as their customer platform, driven by our focus on customers and our pace of product innovation. In the upmarket segment, we continue to see strong momentum in large deals and Multi Hub Wins trends that have remained consistent throughout this year. Two main factors are driving larger deals. First, our product market fit has improved significantly in upmarket and second, our platform's ease of use and ability to deliver quick results resonate with scaling companies. Discerning upmarket buyers want lower costs, high value and great adoption in a matter of weeks. We deliver on all of these, making HubSpot an easy choice for them. Multi Hub Wins are driven by customers looking to consolidate their tech stack, another level of innovation in our hubs like Content Hub and service hub. In Q3, more than 50% of our new business in Pro plus tiers came from customers using three or more hubs. Additionally, over 40% of our install base of customers now use all three core marketing, sales and service, highlighting the value our customers find in HubSpot's unified customer platform. It has been a great year for Content Hub with rapid growth driven by AI innovation. We added video capabilities to our popular Content Remix feature and launched Content Agent that helps create and personalize content. Customers are quickly adopting these AI features to create landing pages, videos and blog posts and they're seeing immediate value. For example, Franchise Brokers association, our customer, who connects great leaders with franchise opportunities, increase content production by 250% and improve organic lead generation by 216% using tools like our Blog Writer and Content Remix. The level of innovation with AI features in Content Hub has accelerated growth and the Attach rate to Marketing Hub is Strong at nearly 50%. In Service Hub, we introduced new features to better support larger customers, including a customer agent that helps answer customer questions, a new customer success workspace to help teams improve retention, and enhancements to the help desk. These innovations are driving higher attach and upgrade rates. Customers appreciate having tickets and conversations in one workspace, which is making them more productive. With the level of innovation and recent launches targeted at customers with larger service teams, we have seen customers with 100 plus service hub seats grow 60% year-over-year. Overall, I am thrilled with the progress we are making across product innovation and go to market execution to drive up market momentum. In the lower-end of our segment, we've continued to drive strong customer growth by improving our product and pricing. Our pricing strategy is working. We lowered the seat price to make it easy for customers to get started and we removed seat minimums to make it easy for customers to upgrade and grow. With HubSpot, we made significant progress in driving higher volumes of customers, which is now offsetting expected ASP decline. We've alsoimproved our free and starter tiers to increase conversion rates. We added personalized upgrade prompts throughout the customer journey to encourage more customers to move from free to starter and drive conversion rates. In addition, we relaunched the starter tier in July which is improved customer experience. All of these changes have helped us drive net customer growth in this segment. Now the highlight of Q3 was of course our Annual Inbound Conference where we launched a significant set of AI innovations that were very well received by our customers and partners. The event was a huge success, attracting over 12,000 in person attendees and over 40,000 online. The conference and the campaigns following have generated nearly one billion impressions, creating tremendous momentum as we closed out Q3. While Inbound showcased over 200 new innovations, the two standout moments were the launches of Breeze and Breeze Intelligence. Here's a quick recap of what we launched in the customer feedback sofar. At Inbound, we launched breeze, which is HubSpot's AI that powers the entire platform in including Copilot, agents, new features and an agent marketplace. Our strategy is to embed AI into every hub and across the entire platform and democratize AI for scaling companies. Since the launch, we have seen a notable increase in AI awareness, adoption and usage. AI awareness within HubSpot grew by 13% quarter over quarter, with two thirds of enterprise and half of pro customers engaging with AI features. Copilot, our AI assistant, has resonated well, particularly with startup customers who use it to summarize CRM data and objects, rewrite text and generate insights from their customer data. Copilot is now in public beta and we are seeing Repeat usage with 43% of users, which is a strong start. We alsolaunched four agents at Inbound: Social, Content, Prospecting and Customer. Though still in beta, customers are already seeing value, for example Kaplan early learning company is using our customer agent to enable 25% to 30% of their customers to self-serve, reducing average ticket response time by 30%. Morehouse College is using our content agent to create blogs with best practices which has resulted in 30% increase in page views and 27% more time spent on their site. Exactly the kind of results content marketers are looking to drive with AI today. And we know AI is only as good as the data that powers it, which is why we alsolaunched Breeze Intelligence to provide our customers with the best possible data about their customers. To recap, Breeze Intelligence does three things. It enriches company and contact data with over 200 million data points, provides buyer intent signals to prioritize prospects and when those prospects visit their website, shortens fonts to increase conversion all out of the box in HubSpot. While this is still in beta, it has been ungated now for all customers and there is clear enthusiasm. Customers are using it for lead scoring to see if the company is in their ideal customer profile. Lead routing to send leads to the right reps. Segmentation and personalization to ensure the right messaging gets to the right person. It's early days, but the trends from our September cohort are strong with high activation and repeat usage rates. And finally, let's talk about our recent acquisition of Cash Flow and how we are advancing our commerce vision. Everything we do at HubSpot is in service of one clear goal Solving for the customer. In 2023, we launched commerce Hub based on the belief that for businesses to grow, they not only need customer data but alsoneed transaction data. What they bought, when they paid, how long they have, until renewal; we've made progress by offering simple billing and payment with Commerce Hub processing more than one billion in GMV with strong year-over-year growth in enrollment. By acquiring Cash Flow, we're doubling down to provide subscription management and robust configuration pricing and quoting CPQ tools right in HubSpot. That means our customers will be able to close deals faster and increase revenue while having their customer and transaction data in one place. Sarika and Brian, the founders at Cashflow, have decades of experience in the space and have built a high performing team focused on removing the friction when a prospect decides to purchase. One of HubSpot's competitive advantages is having a crafted product and that is a promise we intend to keep with acquisitions. To wrap up, we doubled down on product innovation and we are leading with AI and data. We understand what it takes to help SMBs grow a platform that is easy, fast and unified. And that is exactly why our customers are consolidating on HubSpot as their platform of choice. With our relentless focus on innovation and solid momentum in Q3, I'm more confident than ever in HubSpot's durable growth. A huge thank you to all HubSpotters around the world for staying focused on our customers every single day. With that, I'll turn the call over to Kate to take you through Q3 results in more detail.
