OpenAI said Thursday that Chief Revenue Officer Denise Dresser is leaving, marking the latest departure at the artificial intelligence lab.
Dresser will step down to "pursue other opportunities following a transition period," the maker of AI chatbot ChatGPT said. She joined OpenAI in December.
Dali Rajic will replace Dresser as chief revenue officer, the company said Thursday. Rajic most recently served as chief operating officer of Alphabet's (GOOG, GOOGL) Google Cloud subsidiary Wiz.
"The way we're deploying this technology is changing rapidly, and Dali will turn what we've learned into repeatable execution as we build out the full system to make AI broadly useful for people and businesses," OpenAI President Greg Brockman said.
Earlier this week, longtime OpenAI executive Brad Lightcap said he was leaving the company to "start something new." Lightcap will be around for "the next few weeks," he said Tuesday in a post on social media platform X.
Lightcap joined OpenAI in 2018 and held numerous senior leadership roles, according to CNBC.
In July, another OpenAI executive, Fidji Simo, said she had decided to leave her full-time role at the firm and transition to being a part-time adviser to help recover from a "chronic illness."
Earlier in the year, OpenAI confidentially filed for a potential initial public offering in the US. The company closed a $122 billion funding round at an $852 billion post-money valuation, it said at the end of March. ChatGPT had more than 900 million weekly active users at the time.
