Bill McDermott
Chairman at ServiceNow
Thank you very much, Darren, and thank you, everyone, for joining today's call. ServiceNow's first quarter results were outstanding. We once again outperformed our guidance across all top line and profitability metrics. Subscription revenue grew by 24.5% year-over-year in constant currency. That's approximately 50 basis points above the high end of our guidance. CRPO grew 21% year-over-year in constant currency, 100 basis points above our guidance. Operating margin was over 30%, 150 basis points above our guidance. Even as Q1 is not traditionally a large quarter, we had eight deals over $5 million in net new ACV, a 100% increase year-over-year.
Four deals were over $10 million, which is a 300% increase year-over-year. ServiceNow is strengthening its position as the AI platform for business transformation. This is fueling strong performances for each of our key businesses. ITSM and ITOM were each in 16 of the top 20 deals. Security and risk, combined were in 11 of the top 20, customer creator and employee workflows were in 10 of the top 20 deals. GenAI adoption remained on a tear in Q1. Companies are leaning into GenAI as a powerful deflationary force to drive productivity. That's why NNACV for Pro Plus is record-breaking. In fact, it's the fastest selling offering in the company's history. Iconic brands are adopting ServiceNow's Now Assist AI as a standard for their GenAI roadmaps.
This quarter, we expanded our long-standing partnership with Microsoft to include new Generative AI capabilities while also integrating Now Assist AI and Copilot into employee experiences, really exciting. Hitachi Energy is using case summarization with NowAssist for ITSM to resolve cases faster, saving millions. Equinix is deploying NowAssist AI for HR workflows, aiming to increase agent productivity by 30%. ServiceNow at IBM are combining the power of the Now Platform with Watson X to increase productivity for IBM's employees, customers, and partners. BNY Mellon and ServiceNow are exploring the utilization of AI and other leading technologies and IT service management helping to unlock additional value for the bank and its clients.
We look forward to further demonstrating the exceptional Gen AI customer successes and a detailed roadmap at our Financial Analyst Day on May 6th in Las Vegas. From an industry perspective, public sector continues to excel globally. Major transactions in Q1 included government of Australia's Health Department and the government of Italy's IT division, Sojek. The government of Sao Paulo Motor Vehicle Department created an app on ServiceNow to give customers, in that case, Citizens, a fast, transparent digital experience that handles requests in minutes. Our global footprint is booming. We're seeing a vast expansion in our most important geographies. This quarter, our Japan team signed the largest NNHCV deal in its history.
Novartis in Switzerland is implementing ServiceNow Gen AI technology to transform the business into one of the most innovative companies in therapeutic medicine. NEOM is harnessing ServiceNow's single data model along with other partners to scale its IT services across the Middle East region, while seeking to create the first cognitive city where data-driven intelligence meets urban everyday needs. Suzuki, Tokyo Gas iNet, ANA systems are all top deals signed in Q1. And this is just scratching the surface of what we achieved this quarter. There's a lot of guesswork out there right now about the geopolitics and economic policies among other things.
ServiceNow's philosophy is simple. We focus on the things we can control, building great products, delivering great service for our customers, and forging a winning culture, where people can do the best work of their careers. And that's why we perform well when some others don't. It's also why our guidance, as you'll hear from Gina, remains ever strong. Let's talk about the demand environment for enterprise software. AI is not simply a fast maturing technology. AI is a catalyst for business transformation. When I speak to CEOs all over the world, they recognize this is a change moment.
Over the past 15 years, enterprise has experienced a massive decentralization of technology governance. As every department became an IT buyer, the result was too many systems, too many apps, low data quality, and high vulnerability to cybersecurity risk. And here's the key. Those decisions have been made. So, even as CEOs want to consolidate on to strategic platforms for the long-term, they also don't want to delay the potential of net new innovation in the short-term. They want to derisk the past while getting immediate business value from AI. Process optimization is the number one Gen AI use case in the global economy today. This is why ServiceNow's strategic relevance as the AI platform for business transformation has never been higher.
Every business workflow in every enterprise will be engineered with Gen AI at its core. We are the single pane of glass that enables end-to-end digital transformation. At ServiceNow, we pride ourselves on being the living embodiment of an AI run company through our Now on Now strategy. Every week that passes the impact of our own Now on Now AI deployments continues to grow. Gen AI depletion rates have doubled for both our employees and customers, and they are improving each and every month. So for engineers are accepting 48% of Texaco generation. These are meaningful productivity improvements and it's only the beginning. That's why IDC estimates an $11 trillion impact from AI in the next three years. It's also why businesses will spend more than $0.5 trillion on Gen AI in 2027, according to IDC.
So contrary to some opinions out there, we are witnessing the biggest enterprise software market opportunity in a generation. Business leaders are waking up to the fact that they have a fresh choice now. They can radically simplify the tech stack. We are entering a new frontier. We are in a race to put AI to work for people, and that's a ray ServiceNow intends to win for our customers. There's a lot happening at ServiceNow that only heightens our optimism for the remainder of this year and beyond. Our recent Washington, D.C. platform release included very exciting new features for our customers. Now Assist AI for ITOM AIOPs supercharges ServiceNow's market-leading solution, applying generative AI to speed up issue resolution.
Sales and order management unites the sales order life cycles across the front, middle and back office teams on the ServiceNow platform. ServiceNow is also staying at the forefront of building innovative enterprise Gen AI applications. As one example, Now Assist AI for telecommunications service management, what we call TSM, which also uses NVIDIA AI, will boost agent productivity and build on our great partnership. It's also worth noting the ServiceNow research team is stacked with world-renowned AI experts helping our customers stay on the cutting edge.
We're expanding our ecosystem capacity to meet growing customer demand. One example is our investment in platformation, a global IT consultancy and leading ServiceNow implementation partner to enhance expertise and generative AI-enabled technology. And anyone who'd like to get the full story, I warmly invite you to join us for Knowledge 2024 in Las Vegas on May 7. In closing, I'll end how I began, the company is in a market-leading position. We have the product recognition from the industry analysts. All of them were showing up on all of the most admired company lists and we're moving up the ranks every year. Those things are always encouraging, and we're proud of it all.
But the biggest indication I can give you is qualitative. It's how our team feels about what we're doing together. This culture is different. It's rooted in ServiceNow as early as days as a customer-obsessed company. We are ever-hungry, ever-humble. So when I'm told that over 1 million people applied to join us last year, I'm not surprised. When you have a galvanizing ambition to become the defining enterprise software company in the 21st century, people want to be a part of that. They recognize this is about more than technology. This is about helping people to know more, care more and do more. We'll continue on this mission in Q2. I'd like to thank all of you for the trust that you've invested in ServiceNow. We're going to keep working hard for you, and we're going to keep striving to honor our brand promise. The world works with ServiceNow. I'll now hand things over to our outstanding CFO, Gina Mastantuono. Gina, over to you.
