Denise Dresser, Chief Revenue Officer at OpenAI, will depart the artificial intelligence company in the coming weeks, marking the second executive exit this week. OpenAI announced the appointment of Dali Rajic as Dresser's replacement, tasking him with leading the company's global revenue organization.
Dresser joined OpenAI in December 2025, taking on the responsibility of overseeing the company's global revenue strategy across enterprise and customer success. Her departure follows that of Brad Lightcap, OpenAI's former COO and a close associate of CEO Sam Altman, who announced his exit earlier this week after eight years with the company. Dresser confirmed her decision to leave in a LinkedIn post, stating she would pursue other opportunities, and will remain with OpenAI for a transition period to support customers and the business team.
Rajic brings extensive experience in scaling enterprise software businesses. Most recently, he served as President and Chief Operating Officer of Wiz, a cybersecurity firm acquired by Google. Prior to Wiz, Rajic held leadership roles at Zscaler, including as President of Go-to-Market and Chief Revenue Officer before becoming COO, and at AppDynamics as Chief Customer and Revenue Officer. OpenAI highlighted Rajic's expertise in managing metrics-driven revenue organizations with global reach, capable of serving large enterprises and technical clients.
OpenAI stated that Dresser's tenure was instrumental in building the company's commercial foundation, strengthening customer relationships, and establishing the revenue infrastructure that supports its current enterprise business. The company is at an inflection point where the next generation of AI models is expected to significantly alter how work is conducted and how businesses operate. Rajic's appointment signals OpenAI's focus on scaling its revenue operations to meet this evolving landscape.
Dresser's departure adds to a series of leadership changes at OpenAI throughout 2026. Other notable exits include Fidji Simo, who led artificial general intelligence deployment and stepped down last month, and Kevin Weil, former head of research, who departed in April to start his own AI venture. These changes occur as OpenAI prepares for a potential initial public offering. The company reportedly filed its IPO prospectus confidentially in June.
OpenAI's enterprise business has seen substantial growth, with the company reporting over two million business customers, a doubling from the previous year. Dresser had previously indicated that enterprise revenue constituted over 40% of OpenAI's total revenue in April, with projections to match consumer revenue by the end of 2026. This expansion in the enterprise sector is a key focus as OpenAI competes with rivals such as Anthropic for corporate clients.
