An internal memo from OpenAI CRO Denise Dresser, reported by CNBC on April 13, acknowledged that the Microsoft partnership "limited our ability to meet enterprises where they are" — specifically calling out that many enterprise clients prefer Amazon Bedrock over Azure. Dresser described inbound demand for OpenAI's Amazon offering (following the February $50B investment deal) as "frankly staggering," signaling a deliberate pivot toward AWS as the primary enterprise distribution channel. The memo also attacked Anthropic, framing its strategy as built on "fear, restriction, and the idea that a small group of elites should control AI."
