Departure of OpenAI top executives causes unrest among investors ahead of IPO
A wave of high-level departures at OpenAI is worrying investors as the company prepares for a stock market flotation. The recent departure of Denise Dresser, the chief revenue officer, comes shortly after the exit of seasoned executive Brad Lightcap. This perceived instability at the top is seen by some industry observers as an important warning sign, especially since Dresser left after less than a year, potentially forfeiting substantial compensation.
The turnover in management is not limited to these two. Fidji Simo, the former Instacart CEO who moved to OpenAI, recently stepped down for health reasons. Earlier this year, several other key figures, including head of marketing Kate Rouch and vice president of science Kevin Weil, also left the organisation. To plug the revenue gap, OpenAI has appointed Dali Rajic, the former COO at Wiz, as the new chief revenue officer.
This internal unrest comes at a delicate moment for CEO Sam Altman and president Greg Brockman. They must project an image of stability while facing fierce competition from Anthropic and Google, as well as the rise of cheaper, open source AI models. A confidential prospectus for the IPO was filed in June, but no official date for the listing has yet been set.
Despite the turnover in management, the company claims strong financial momentum. Internal communications show that revenue in July grew by more than 20%, with corporate customers posting an increase of 32%. CFO Sarah Friar recently stated that the corporate segment has overtaken the consumer-focused ChatGPT activities in terms of revenue generation. According to company data, the corporate customer base, under Dresser’s leadership, has grown to 2 million users.
Critics and former employees suggest that this instability points to a ‘pressure cooker’ corporate culture characterised by rapid hiring and firing. It is not the first time that OpenAI has faced leadership crises. Altman himself was briefly removed from his position by the board of directors in 2023, before being reinstated. The legal team of US entrepreneur Elon Musk later used that incident in a lawsuit to question Altman’s transparency and management style. President Greg Brockman has also come under scrutiny.
While Brockman has publicly thanked departing employees for their role in the company’s early stages, it has been noted that Altman has not publicly bid farewell to Dresser. Instead, Altman has remained focused on the technical side of the company and has recently promoted the speed of the new GPT-5.6 model.
