Uber President Jill Hazelbaker is set to join OpenAI as Chief Corporate Affairs Officer, filling a role that has been vacant since the start of the year. With prior experience at Google and Snap, she brings a wealth of expertise and will oversee OpenAI's global public relations, communications, and brand strategy. OpenAI's leadership has experienced frequent turnover in recent years, and market anxiety has intensified ahead of a potential IPO. Her mission is to stabilize the team.
