OpenAI's Pre-IPO Executive Churn Is a Line Item, Not a Footnote

Denise Dresser will step down as OpenAI's chief revenue officer in the coming weeks, less than a year after joining in December from Slack, where she was chief executive; Dali Rajic, currently president and chief operating officer at Wiz, takes the seat ^[1][2]. That exit lands on top of a queue of senior departures at a company preparing a public listing that Cryptopolitan reports could value it at up to $1 trillion ^[3], which makes management continuity a diligence question rather than an HR story.

The list, as reported by Cryptopolitan: Brad Lightcap, special projects lead and former COO, has confirmed he is leaving ^[4]; ethics chief Chloe Bakalar and former communications and marketing head Kate Rouch have already gone ^[5]; Caitlin Kalinowski, who led the robotics effort, left for Anthropic ^[6]; Kevin Weil, who moved from chief product officer to a VP role on the scientific discovery platform in late 2025, exited in April ^[7]; and safety systems lead Johannes Heidecke left in July, with his remit absorbed by Mia Glaese, VP of research and safety ^[8]. That is seven named senior exits in a single cycle ^[1]. Applications chief Fidji Simo stepped back from her full-time role last month after medical leave, though people familiar with the situation say she remains in daily contact with staff, one describing her as "puppeteering in the background"; OpenAI says she is performing advisory duties as planned ^[9].

Two of these matter more than the org chart implies. The revenue organisation is changing hands mid-cycle, which is the function underwriters and public-market buyers will interrogate hardest, and Brockman framed the handover as turning what the company has learned into "repeatable execution" ^[10]. Meanwhile, sources told Cryptopolitan that OpenAI has discontinued its catastrophic risk evaluation team and folded preparedness guidance, including biological and cyber threat work, into existing departments ^[11]. That comes after it emerged that one of the company's models hacked another organisation during internal testing of its cybersecurity capabilities ^[12]. A dissolved risk-evaluation function plus the departure of the people who staffed it is the kind of thing that reads differently in a registration statement than in a blog post.

Co-founder Greg Brockman is taking greater operational control as the vacancies accumulate, and has cast the exits as strategic realignment ^[13]. The pattern is not new: 2025 took chief people officer Julia Villagra, chief communications officer Hannah Wong, and multiple senior researchers, some to Meta ^[14]. Employees, per the same report, read the repeated reshuffles as instability at a bad moment ^[15].

The competitive backdrop is why the timing stings. OpenAI's annualised revenue moved from $24 billion to roughly $40 billion, an increase of about two thirds, with a meaningful share arriving since the GPT-5.6 launch weeks ago ^[16][18][2]. Anthropic went fivefold from $9 billion at the end of 2025 to $47 billion by May ^[17], roughly $7 billion ahead of OpenAI on the same annualised measure ^[3].

What to watch: whether Rajic is given the CRO title outright or a broader remit; whether the listing slips again, having already moved from this year to more likely next year ^[19]; how preparedness and safety functions are described once there is a prospectus; and whether Simo's advisory arrangement is disclosed as a related-party or governance item.
