Tanium is turning back to its roots.
The $9 billion cybersecurity company is bringing back cofounder Orion Hindawi as CEO, replacing Dan Streetman after less than four years in the role, as the company looks to navigate the AI upheaval reshaping software companies.
Hindawi's father and another cofounder, David Hindawi, will return to the role of chair, while Streetman leaves the company's board. Prior to Streetman joining the company, Orion Hindawi served as CEO for over 15 years.
Tanium also had a small round of job cuts last week, affecting around 35 employees in research and development, according to sources familiar with the matter. According to a corporate fact sheet, Tanium had 1900 employees as of 2025.
Like many software-as-a-service (SaaS) companies, Tanium has been facing more competitive pressure as AI changes how businesses buy and use enterprise software. The company said it plans to expand its AI offerings and autonomous capabilities. This leadership shake-up follows several executive departures this year, as Business Insider previously reported. Tanium has stayed private since its founding in 2007, and it was last valued at $9 billion in 2020.
"AI has made what we do more critical than ever, and Tanium is the platform every organization will rely on as threats grow more sophisticated and the pace of change intensifies," Orion Hindawi said in a statement.
Tanium hired its chief financial officer, Marc Levine, in 2021 to conduct a "readiness assessment" for an initial public offering. Several employees and executives had left Tanium in the past few years due to uncertainty about whether the company would ever go public, Business Insider previously reported.
Last year, Tanium cracked down on its return-to-office policy by withholding some equity grants from employees who don't comply, Business Insider previously reported.
