OpenAI Chief Revenue Officer Denise Dresser issued a four-page internal memo to employees on Sunday outlining the company's strategic direction and competitive positioning against rival Anthropic.

The memo, viewed by The Verge, emphasizes building a moat around AI products to combat user switching between models. Dresser stressed that multi-product adoption makes OpenAI harder to replace and urged teams to think like a platform company rather than one with separate product lines.

Dresser directly addressed competition with Anthropic, stating the market is as competitive as she has ever seen it. She wrote that Anthropic's coding focus gave them an early advantage but warned against being a single-product company in a platform war.

The memo also accused Anthropic of inflating its stated run rate by roughly $8 billion. Dresser claimed Anthropic uses accounting treatment that grosses up revenue share with Amazon and Google, while OpenAI reports Microsoft revenue share net.

Dresser characterized Anthropic's approach as built on fear and restriction, contrasting it with OpenAI's message of expanding access. The memo comes as both companies reportedly plan to go public this year.

The communication underscores heightened competitive tensions in the enterprise AI market as vendors vie for position ahead of anticipated IPOs.
