OpenAI announced Thursday that Dali Rajic, former president and chief operating officer of cybersecurity firm Wiz, will replace Denise Dresser as chief revenue officer. Dresser, who joined OpenAI in December 2023, is leaving the company after eight months in the role to pursue other opportunities, according to a company statement and her LinkedIn post.
The transition follows the announcement on Tuesday that Brad Lightcap, OpenAI’s longtime chief operating officer, would depart the company after eight years. OpenAI stated Dresser’s responsibilities will be reassigned as part of the company’s ongoing executive restructuring.
OpenAI confirmed in its release that Dresser led the company to 2 million business customers, double the number reported at the start of her tenure. Greg Brockman, OpenAI’s president, praised Dresser’s contributions in a company statement, saying she "led our revenue organization through a formative period for the business."
Dresser, who previously served as a CEO within Salesforce, did not disclose her next career move in her LinkedIn post. OpenAI said her departure would occur after a transition period. The company did not respond to a request for comment from Business Insider regarding Dresser’s exit.
Rajic, who will assume the revenue chief role, previously held executive positions at Wiz, a cybersecurity company acquired by Google for $29 billion in August 2024. OpenAI’s announcement did not specify Rajic’s start date or immediate priorities in the role.
The executive departures coincide with OpenAI’s preparations for an initial public offering expected in 2025, a period marked by intensified competition with rival AI lab Anthropic. OpenAI has emphasized scaling its enterprise customer base and expanding data center capacity to support its commercial growth.
In July, OpenAI lost Johannes Heidecke, head of safety systems, and Joshua Achiam, chief futurist. Fidji Simo, CEO of applications, transitioned to an advisory role in June due to health reasons, according to company statements.
OpenAI’s restructuring follows a broader trend of leadership turnover in the AI sector, where companies are rapidly evolving their business models ahead of potential public listings.
