Another OpenAI executive is departing. Denise Dresser, who joined OpenAI as its chief revenue officer in December after serving as CEO of Slack, will be leaving in the “coming weeks” to “pursue other opportunities,” she said in a team note posted to LinkedIn. Dali Rajic, president and COO of Wiz, will be taking over the CRO role, OpenAI says.

“We’re now at an inflection point: the next generation of models will change not just how work gets done but how companies are built and run,” OpenAI says. “Dali will build the revenue operating system needed to scale for this next phase.”

Dresser is also leaving ahead of OpenAI’s IPO; the company announced in June that it had submitted a confidential S-1 filing to the Securities and Exchange Commission.
