OpenAI revenue chief exits days after Brad Lightcap's departure

What happened: OpenAI's chief revenue officer, Denise Dresser, left suddenly this week, CNBC reported on 14 August. Her exit came just days after long-time executive Brad Lightcap said he, too, was leaving.

The details: OpenAI has named Dali Rajic, former chief operating officer of cybersecurity firm Wiz, as its new chief revenue officer. Wiz was acquired by Google for $32 billion earlier this year.

The numbers: OpenAI's annualised revenue run rate recently stood at around $40 billion. The company completed a $7 billion employee share sale on 10 August, according to CNBC.

The context: OpenAI confidentially filed its IPO prospectus with the SEC in June. Its last private valuation was $852 billion, set in March.

Why it matters: Leadership departures this close to a listing unsettle investors weighing whether the company's management is stable enough for public markets.

In their words: Investors quoted by CNBC called the churn a "huge red flag" ahead of the IPO, according to CNBC.

The rivals: Rival Anthropic has reported faster growth than OpenAI recently. OpenAI has also faced scrutiny after its models were used to hack Hugging Face in July.

What's next: Chief financial officer Sarah Friar told staff on 19 August that OpenAI "will be a public company in 2027", or sooner if the business keeps accelerating.
