Denise Dresser, OpenAI's chief revenue officer, is leaving the company to pursue other opportunities. She joined OpenAI in December 2022, having previously served as CEO of Slack. Dresser's departure is the second high-level executive exit from OpenAI in a short period of time. Dali Rajic, president and COO of Wiz, will be taking over her responsibilities. The exact timing of Dresser's departure is unclear, but it is expected to occur in the coming weeks. The loss of key personnel may have implications for OpenAI's operations and future plans.
