“It’s a little-known fact that OpenAI already serves over 1 million business customers, and I’m excited to help these customers drive the next wave of innovation while also attracting new users to the platform, ” said Scott Rosecrans, formerly AWS’ vice president of AI sales and strategic pursuits, now joining OpenAI. Rosecrans, a top AI sales executive at Amazon Web Services, recently left the cloud giant to join the fast-growing AI startup OpenAI. His mission is to onboard new customers and “drive the next wave of innovation. ” “The current developments in AI remind me of the cloud’s early days when I joined AWS in 2016; the growth potential is enormous, ” Rosecrans remarked. Highlighting OpenAI’s impressive customer base, he reiterated, “OpenAI has over 1 million business customers, and I’m eager to support them as well as bring new clients onto the platform. ” [Related: AWS’ Data Center Network Lead Moves to xAI to Manage ML Infrastructure] Leaving AWS this month, Rosecrans was appointed OpenAI’s vice president of strategic pursuits. He aims to “drive enterprise-scale growth, global expansion, and transformative customer relationships” for the San Francisco-based company. OpenAI’s valuation reached $500 billion after a secondary share sale in late 2025. Amazon and OpenAI finalized a massive $38 billion multi-year agreement in late 2025, under which OpenAI leverages AWS’s AI computing resources, including Nvidia GPUs and Amazon’s proprietary Trainium chips.

OpenAI has already begun running extensive workloads on AWS infrastructure, with plans for significant capacity expansions in the coming years. This partnership also includes integrating OpenAI’s models into Amazon’s Bedrock platform for AWS customers and potential Amazon investments in OpenAI. Furthermore, in 2025, OpenAI introduced advanced open-weight models accessible through Amazon Bedrock and Amazon SageMaker AI for AWS customers. OpenAI did not respond to requests for comment regarding Rosecrans’ hiring by press time. ‘AWS Offers the Strongest Set of Services’ Rosecrans initially joined Seattle-based AWS—an industry leader with a $132 billion annual run rate—in 2016 as vice president of strategic pursuits and remained for over five years. After a brief period at financial software company Stripe, he returned to AWS in 2022 as VP of AI sales and strategic pursuits. He described AWS as “by far the best company” he has worked for during his 32-year career. “AWS boasts the strongest suite of services, outstanding leadership, and, most importantly, an unmatched, relentless customer focus, ” he wrote on LinkedIn. “I’m deeply grateful for my time there and the incredible people I had the privilege to work with and learn from. ” Currently, AWS operates at an annual run rate of $132 billion, while its parent company Amazon holds a market capitalization of $2. 54 trillion.
