Longtime OpenAI Executive Brad Lightcap Departs to Start New Venture
OpenAI makes very smart computer programs that can write, talk, and create pictures.
One of its most important helpers was a man named Brad Lightcap.
He joined the company in 2018 and helped it grow from a small research lab into a big business.
He took care of money, business deals, and building teams like finance, legal, and partnerships.
Now Brad has decided to leave his job to start something new.
He said the decision was a little sad but also exciting.
The main boss, Sam Altman, said OpenAI could not have gotten where it is today without him.
This news comes as OpenAI gets ready to possibly sell shares to the public for the first time, and the company could be worth more than one trillion dollars.
Several other important people at OpenAI have also left their jobs recently.
Brad says he will keep supporting OpenAI's mission from outside the company.
Brad Lightcap, OpenAI's longtime chief operating officer and close aide to CEO Sam Altman, announced Tuesday he is leaving after eight years to start a new venture.
Lightcap joined OpenAI in 2018 as chief financial officer, was promoted to COO in 2022, and moved to lead special projects in April.
He called the decision "bittersweet" and said he will support OpenAI's mission from a different vantage point, without remaining in internal leadership.
Sam Altman said Lightcap was among the few who understood the mission when it sounded "totally crazy" and that OpenAI would not be where it is today without him.
The exit comes as OpenAI prepares for a possible IPO, with a valuation of around $852 billion that could cross $1 trillion, amid several other senior departures.

Former OpenAI employees and researchers
Former OpenAI employees raised concerns that researchers felt less free to publish work highlighting the economic risks of AI, with reports saying the company had become more cautious about research that could cast AI in a negative light.
