Thank you, Chris, and good afternoon, everyone. We delivered another strong fourth quarter, generating $131 million in revenue, up 33% versus the prior year and 6% compared to the prior quarter, again demonstrating the high ROI and long-term value of the Braze Customer Engagement Platform. Our solid performance comes despite a selling environment that has remained challenging all year due to macro considerations and its associated scrutiny on budgets. We have continued advancing our strategy and evolving our execution in order to simultaneously deliver strong revenue growth and enhanced operating efficiency, improving non-GAAP gross margins by 90 basis points year-over-year and non-GAAP operating margin by over 1,100 basis points compared to the fourth quarter of last year. We were again pleased with the strength of our enterprise business, as we continue to capitalize on the legacy vendor replacement cycle and consolidation trend. And we achieved record upsell this quarter, as customers continue to grow with Braze adopting more channels, deploying more use cases, increasing their volumes, and adding new business units and geographies. In fact, this quarter, we secured our first eight-figure customers through upsell with the media and entertainment conglomerate, who has consistently grown with Braze over the past eight years. Continued expansion opportunities like these with our long-term customers speaks to our pace of innovation, stability and reliability at scale and our leadership of the customer engagement category. As enterprise remains a strength for us, our roster of $500,000 plus ARR customers continues to grow as well, rising to 202 in the quarter, up 29% year-over-year, a testament to how customers continue to leverage rich first-party data and advanced artificial intelligence to drive sophisticated cross-channel customer engagement at scale. Notable new business wins and upsells in the quarter include AB InBev, Bojangles, DraftKings, FanDuel, Flix SE, which is the parent company of both FlixBus and Greyhound, and Nestle Purina among many others. We're also pleased to share that earlier in fiscal year 2024, we secured new relationships with both DoorDash and Wendy's. The performance, reliability and scalability of our platform is a core component of what many of these brands appreciate about Braze. Earlier this week, we published scalability and performance metrics for our full calendar year 2023, which included over 2.6 trillion outgoing actions, including the sending of messages execution of webhooks and other campus operations that transform data and manage audiences. Inbound, we processed over 7.5 trillion API calls with a 99.99% average system-wide uptime across all customers and products. Whether those API calls originate from our SDKs running in our customers' products, partner integrations or custom software running in our customers' back-ends, these API calls deliver constantly evolving context about users and their actions in order to trigger messages and drive personalization strategies, showcasing the growing sophistication among Braze customers as they tailor the communications to each individual recipients. During 2023, we also saw year-over-year growth of over 60% from messages sent with Braze Canvas, our no-code visual development environment, which marketers used to quickly implement sophisticated customer engagement strategies. This increase in usage reflects a rise in multi-step cross-channel messaging flows and the continued adoption of sophisticated orchestration, experimentation, and personalization techniques, all supported by Sage AI. Designed from the ground up to scale with demand, support massive scale at speed, and minimize outages, our system is exceptionally reliable even when faced with some of the world's largest consumer audiences. All of these metrics build on our privacy and security by design, which integrates safeguards at every level of our operation and is reflected in our privacy processes and security certifications. As the customer engagement landscape evolves, we continue to win against a large field of competitors, who cannot reliably deliver on real-time use cases, have limited channel selection or flexibility, a lower sophistication ceiling, or simply don't scale. Similarly, we continue to make progress replacing legacy marketing clouds as marketers realize that those clouds disjointed and siloed solutions are increasingly unsuited for modern customer engagement use cases. This quarter we replaced legacy marketing clouds at a European-based transportation company, a leading American health non-profit, a UK-based QSR, and a Japan-based digital software developer among others. In addition, this quarter we replaced point solution competitors at a design and collaboration platform, an athletics clothing retailer and a mobile gaming company. As I mentioned last quarter, we've been very happy with the execution of our sales team in the second half as we continue to navigate a choppy macro. And our competitive wins across verticals and geographies demonstrate both the flexibility and versatility of our platform as well as the enormous future potential of our business. Braze has the right to compete and win with virtually any organization that has ambition or sophistication around customer engagement. If your organization has a person whose job is customer engagement, we believe Braze is the best-in-class solution for them. In order to maintain our technical lead, we continue to invest in improving the capabilities of the Braze platform. With the wealth of data captured by Braze and the introduction of AI-powered tools, marketers are able to enhance relevance and performance, while saving time and energy in production. In order to meet the demands of this paradigm shift, we're infusing AI throughout our stack to help marketers efficiently implement highly personalized cross-channel strategies. Last year we launched Sage AI by Braze to inform and scale personalized sophisticated and lasting experiences that consumers love. At that time, we spoke to you about some of the exciting enhancements under development that further empower brands to embrace the craft of customer engagement, allowing them to move beyond simply sending messages. Just yesterday, we announced new features that simplify and accelerate the ability of marketers to tailor recommendations to each unique customer further unlocking sophisticated personalization and prediction at scale, inspiring creativity, and driving high-value actions from customers. At the same time, each feature is easily accessible and located intuitively across the marketers' workflow to support more creative testing, optimization, and personalization. These innovations include AI item recommendations, personalized path, tone control and estimated real open e-mail rates. All of these features leverage comprehensive first-party data inputs in real time, allowing for smarter decision-making and powering better business outcomes. Let me take a moment to walk through each of these offerings. Last fall, I mentioned the development of AI item recommendations. Today, I'm pleased to announce that this engine, which uses AI to enhance message relevance with better product, service and catalog recommendations, is now generally available. AI item recommendations leverages cutting-edge, transformer-driven AI models and is layered on top of Braze catalogs to enable easier setup and tighter integration with the rest of the Braze Stack. Accordingly, these recommendations can be used across every channel that Braze offers and as part of sophisticated cross-channel journeys in Canvas. We believe AI item recommendations will increase campaign revenue and improve customer loyalty for the brands that deploy it. I'm also pleased to announce the release of Personalized Paths, an automated decision-making feature within Canvas that scales personalization by matching each customer with the message copy creative channel and offer that they are most likely to engage with. It can be incorporated at any point in the Canvas journey and used across any channel, allowing it to be combined with sophisticated personalization and orchestration techniques. Personalized Paths enable marketers to leverage AI to deliver more value to their customers through deeply customized experiences, while also saving time for them, and their colleagues and engineering, even as they delve into more sophisticated experimentation. In addition to the work we're doing using our own custom models, we also continue to deliver productivity enhancements that utilize prompt engineering and fine-tuning of publicly available models like OpenAI's GPT-4. Recall that we integrated ChatGPT and DALL-E into Braze in May and December of 2022, respectively, before the AI hype of early 2023. And it's been exciting to see how customers have used and experimented with these features. We believe there is even more potential for marketing teams to quickly generate and validate creative assets to support more effective campaign creation and testing while maintaining brand voice and safety. Now we have built-in generative functionality, we call tone control, which helps marketers dictate and control the tone of AI-generated copy directly in Braze. This can save marketers time, help them craft more authentic experiences, foster additional creativity, quickly generate variants for testing and experimentation, and help eliminate mistakes. Finally, I'd like to highlight our estimated real open rates feature, another use of machine learning that allows Braze customers to continue to rely on data-driven content strategies even as changes in the privacy landscape obscure certain data inputs. This solution addresses the changes made by Apple's Mail Privacy Protection program, offering marketers a more complete view of open rates for email campaigns by controlling for the uncertainty created by Mail Privacy Protection's Machine Opens. One early AI customer success story that I'd like to highlight is from KoRo Drogerie, a German superfood e-commerce company, which tested our new AI item recommendation offering to help determine what products to offer to which customers and drive purchase decisions. KoRo syncs their product catalog into Braze in real-time with Braze's cloud data ingestion feature and can then intelligently suggest product offerings tailored to individual customer preferences. By combining the simplicity of Braze's cloud data ingestion with the power of AI item recommendation, KoRo gained valuable insights into new user behaviors, empowering them to deliver highly personalized recommendations from their extensive catalog of over 1,000 products. In addition, they drove these improved results with significantly less effort, automating everything from the data warehouse to the personalized recommendations seen by customers. Most importantly, KoRo tripled their purchase rates when these personalized product suggestions were incorporated into their onboarding messaging flows. Our pace of innovation and ease of use also continue to earn industry accolades for our excellence in software products. Recently, G2, the largest and most trusted marketplace for software, recognized Braze across six categories in its annual best software awards, including the categories Best Software Products, Global Software Companies, Highest Satisfaction Products, Marketing and Digital Advertising Products, Products for Enterprise, and Products for Mid-Market. Our solutions' inclusion in the G2 Best Software Awards is a testament of the strength and loyalty of our customer community and our ability to deliver high ROI solutions that our customers need to power outstanding customer engagement for their users. Before I turn it over to Isabel, I want to update you on our latest social impact initiatives. In 2021, Braze joined the Pledge 1% movement, through which we have reserved nearly a million shares of our Class A common stock to donate to a donor advice fund. Thus far, Braze has surpassed more than $1 million in grants via our Braze for Social Impact Fund, of which more than half have been directed by employee grant programs. Our Social Impact mission is to amplify employee impact, to create opportunities for underserved groups within our communities, and to accelerate science-based climate solutions. We look forward to growing these efforts through continued employee advocacy and participation over time. Thank you for your continued support at Braze. We are very excited for the year ahead. Our strategy of driving innovation to create industry-leading solutions remains unchanged, and we believe our investments in new product growth channels and advanced AI and machine learning, coupled with strong secular customer engagement tailwinds, will keep Braze on the path to becoming the industry standard for cross-channel customer engagement. And now, I'll turn the call over to Isabel.
