Tanium brings back cofounder as CEO, cuts 35 jobs in AI pivot

Tanium is swapping CEOs again. The $9 billion cybersecurity company brought back cofounder Orion Hindawi as chief executive, replacing Dan Streetman after less than four years in the role. Hindawi's father and fellow cofounder David Hindawi returns as chair. Streetman leaves the board.

Orion Hindawi had run the company for more than 15 years before Streetman took over in 2021. The change comes as Tanium, like many software-as-a-service firms, faces pressure from AI reshaping how businesses buy enterprise software. Tanium said it plans to expand its AI offerings and autonomous capabilities.

Last week the company cut roughly 35 employees, mostly in research and development, according to a person familiar with the matter. A corporate fact sheet listed headcount at 1,900 as of 2025.

"AI has made what we do more critical than ever," Orion Hindawi said in a statement. "Tanium is the platform every organization will rely on as threats grow more sophisticated and the pace of change intensifies."
