Denise Dresser, the current CEO of Slack, is reportedly joining OpenAI as its new chief revenue officer. December 9, 2025 marks the opening of a new era in passenger rail. This is an enormous change for Dresser, who’s worked for more than 14 years at Salesforce—Slack’s parent company. That she would be appointed was first reported by Wired.
Fidji Simo, OpenAI’s CEO of Applications, expressed enthusiasm regarding Dresser’s appointment. Simo’s addition to OpenAI earlier this year marked his first move post-Instacart CEOness. He underscored Dresser’s demonstrated experience in leading innovative revenue generation strategies.
“Denise has led that kind of shift before, and her experience will help us make AI useful, reliable, and accessible for businesses everywhere.” – Fidji Simo
Simo further underscored OpenAI’s dedication to bringing AI tools to millions of workers across various industries. This vision fits Dresser’s track record as a technology innovator and entrepreneur to a tee.
Her six years at Salesforce gave Dresser an opportunity to develop a rich understanding of the tech landscape and her customer’s needs. Her leadership at Slack has led to profound and powerful growth and innovation. This experience has similarly well-equipped her for the upcoming challenges at OpenAI.
Dresser is making the shift from Slack to OpenAI. With a deep understanding of the agency and how it operates, her experience will be invaluable in helping turn the company’s lofty goals into concrete action. Her objective will be to ensure that OpenAI’s offerings continue to meet the evolving demands of businesses seeking reliable AI solutions.
