OpenAI is swapping out its top revenue executive just as it tries to convert extraordinary AI reach into a public-market-ready business. The change hands co-founder Greg Brockman more operational influence—and intensifies scrutiny of a leadership team already in flux.

Dresser joined OpenAI in December from Slack, where she had been CEO, to lead commercial growth. In recent months, however, the company’s senior ranks have thinned: former chief operating officer Brad Lightcap announced his departure, while former applications chief Fidji Simo moved to an advisory role after health-related leave. Reporting has also chronicled exits from safety, ethics and alignment roles, feeding the perception of a broad reset rather than a routine sales succession.¹

On Thursday, Dresser said she had made the “difficult decision to leave OpenAI in the coming weeks to pursue other opportunities.”² OpenAI named Dali Rajic, the former president and COO of Wiz, as her replacement. The company’s official account presents continuity alongside acceleration: it says Dresser built the commercial foundation as its products reached more than 1 billion weekly users and 2 million businesses—double the business count a year earlier.³

Brockman’s framing is that the business needs execution, not merely a new face. “The way we’re deploying this technology is changing rapidly,” he said, adding that Rajic would turn the company’s lessons into “repeatable execution.”³ Rajic, whose résumé also includes Zscaler and AppDynamics, has been brought in to build what OpenAI calls a metrics-led global revenue operation.

Outside reporting casts the move more sharply: Brockman is consolidating responsibility as OpenAI seeks to outrun Anthropic in enterprise adoption and prepares for an anticipated IPO.⁴ OpenAI says the next generation of models will reshape “how companies are built and run”; its immediate test is whether a reshuffled leadership team can turn that ambition into durable enterprise revenue.³
