Thanks, Emily, and thanks, everyone, for joining our call this afternoon. I'm pleased to report strong first quarter results with our subscription revenue growing 20% year-over-year and total revenue exceeding the midpoint of our guidance by 3 percentage points. As a reminder, our subscription revenue, which others in the industry refer to as cloud revenue accounts for nearly 80% of our total revenue. Also, this 20% growth in subscription revenue does not include any benefit whatsoever from customers converting from on-premise to cloud since we do not have any on-premise business, and this growth is all organic, except for an immaterial amount. Adjusted EBITDA margin for the first quarter was 15% of revenue, helping drive strong LTM operating cash flow of $128 million or 14% of revenue. As you all know, we take a balanced approach to delivering top line growth and bottom line profitability. I will begin today by discussing our broader market opportunity, which continues to be propelled by 3 ongoing trends. First, the migration to cloud contact center platforms continues to be a top priority for enterprises, particularly as many on-prem solutions are being end of life. With current cloud penetration standing at approximately 25% to 30%, we believe there's a multiyear durable growth opportunity ahead. Second, enterprises are laser-focused on improving customer experience, which has become a strategic initiative aimed at driving better business outcomes. With our intelligent CX platform and our passionate experts, we are changing the game for some of the largest brands in the world and helping them reimagine their customer experience. And third, AI is revolutionizing the way brands enhance customer experience. With our AI-infused and data-driven intelligent CX platform, we're helping enterprises deliver personalized, connected and effortless experiences for their customers. These 3 trends are driving a massive market opportunity, and we are a clear market leader, given our platform, our success in marching up market and our strong international expansion. And now let me take each of those 3 growth drivers in order, starting with our platform. Five9's AI leadership has been a key reason why customers choose us. Our AI strategy is simple. We combine the power of the industry's leading engines with contextual data unique to each of our customers. We have always believed it's optimal to leverage the best engines in the industry, and the arrival of generative AI has further validated that strategy. Because of this, we believe we have established a significant lead in this market. By embracing the best engines and expanding them with contextual data, we can easily produce basic industry models. But more importantly, we can go beyond that to produce customer-specific models that are setting new standards in providing exceptional customer experience and also doing it responsibly by protecting the privacy of their data. Additionally, empowering customers with this is not just a matter of technology, it's also a matter of people. Five9's experts work hand-in-hand with our customers to gather the right data from the right sources to deliver these customer-specific models, resulting in what really matters, personalized CX and better business outcomes. We believe this strategy has allowed us to be more nimble than our competitors in adopting generative AI and using it across our platform. This has been demonstrated through our recent announcement of GenAI Studio, the industry's first tool that easily allows enterprises to combine best-in-class engines with their unique contextual data and to customize the models on an interaction-by-interaction basis, allowing for new levels of personalization. GenAI studio can be customized by integrating any piece of data that our platform accesses during the processing of an interaction. This allows customers to leverage investments they've already made in integrations in our platform, which is one of the more complex and time-consuming aspects of implementation. This enables us to supercharge their results when they attach our AI products. Feedback from customers has been overwhelmingly positive as they will begin to gain these benefits in just a few days, given the ease of use of GenAI Studio. And it's not just customers saying, we're ahead. We continue to earn awards and industry recognition from marquee analysts. And of course, nothing speaks to the success of our strategy more than numbers. For example, our AI and automation ARR bookings grew 15x year-over-year in the first quarter. And now I'd like to focus on our march-up market and international expansion. We're very excited to share that we signed our largest deal effort, a Fortune 50 financial services company, which is a testament to our continuing success in marching up market. Dan will share more details in a moment. But I just want to say, we're thrilled to add this win to our previously announced mega deals, such as the parcel delivery company, the health care conglomerate and the global health care insurance company. Additionally, as a result of this win, enterprises and the financial services industry are taking notice, and they're already pulling us into large financial services opportunities. As a reminder, our success up market is not just due to our award-winning platform but also because of our people and our partners. Our customer success model remains a key differentiator, as we have hundreds of CX experts globally at Five9, who execute repeatable large enterprise playbook that focuses on transformation, migration, implementation and ongoing optimization. Additionally, our collaboration with Premier CX partners around the world is driving our upmarket success and international expansion, as demonstrated by the following 3 examples. First, we are seeing increased momentum from large SIs. We have an ongoing initiative called [indiscernible], which enables and certifies a select group of partners to take on implementation and support services, and it is incentivizing these SIs to lead with Five9 in some of the largest global opportunities. Second, our Salesforce partnership continues to gain momentum, where we have become the first and only CCaaS partner of Salesforce to reach Summit status. This is a major step forward for our partnership. And it gives us early access to releases and APIs so that we can stay at the forefront with Salesforce. Our advanced BYOT integration for Service Cloud Voice is a great testament to this partnership. And third, our BT partnership is taking hold. As a reminder, we have a go-to-market reciprocal arrangement where they resell our Five9 solutions, and we also resell BT connectivity. This is not only improving itself in the U.K. and Ireland markets, but also in other parts of the world, where they've been instrumental in helping introduce and secure Five9 business. These are just a few examples of our partners helping pull Five9 upmarket and also helping expand our global footprint. Before I turn it over to Dan, I'd like to make a few comments on our journey as a public company. As many of you may have seen a few weeks ago on April 4, we celebrated the 10-year anniversary of Five9's IPO by ringing the opening bell at NASDAQ. It was a perfect opportunity to reflect on our journey as a public company. Over these last 10 years, we've made significant progress on multiple vectors, including the following 5 examples. We grew revenue by 10x in that 10-year period, virtually all organically. We increased EBITDA margins by 43 percentage points. We increased the number of $1 million plus ARR customers from 3 to 183. We were one of the early pioneers of cloud contact center and have become a clear market leader and the largest pure-play cloud provider in our industry. And more recently, we have been leading the AI revolution in Contact Center and CX. Today, we're changing the game for many of the largest brands in the world as we help them reimagine CX with our AI-infused data-centric platform combined with our passionate experts. In addition to reflecting on our progress, I'd like to take a moment to thank our team of Five9ers. Our success over the last decade has been driven by their teamwork, commitment and passion, and I want to personally thank every Five9er for all you do. We are still in the early stages of a massive transformation in CX, and I'm super excited about what we can achieve over the next 10 years. And with that, I will turn it over to our President and CRO, Dan Burkland. Dan, please go ahead.
