Tanium Inc.

Is Tanium publicly traded?

No. Tanium is a private, venture-backed company. Its shares trade only on private secondary markets. An IPO has been anticipated for years but no date has been set.

Who founded Tanium?

Father and son David and Orion Hindawi founded the company in 2007 in Emeryville, California. They previously built BigFix, which IBM acquired in 2010.

What is Tanium worth?

Its last primary funding round, led by Ontario Teachers' Pension Plan in early 2021, valued the company at approximately $9 billion. Secondary market pricing in 2026 implies a lower current mark.

Where is Tanium headquartered?

Tanium is headquartered in Kirkland, Washington, on the Seattle waterfront at Carillon Point. It moved from Emeryville, California, in 2020 but retains a major operations center there.

What does Tanium do?

It sells endpoint management and security software that gives IT teams real-time visibility and control over every device on a network. Customers use it for patching, compliance, threat detection, and incident response across more than 33 million endpoints.

David and Orion Hindawi founded Tanium in July 2007 in Emeryville, California. It was their second company: the pair had built BigFix, an endpoint management firm started during the dot-com era, which IBM acquired in 2010 for a reported $400 million. Both left BigFix before the sale closed and started Tanium to build what they considered a more scalable successor.

For seven years the company ran without venture capital, funded by the founders. In 2014 and 2015 it accepted outside money for the first time, including a $90 million round led by Andreessen Horowitz, beginning a run of financings that eventually topped $1 billion. TPG invested $175 million in 2018, and a 2021 round led by Ontario Teachers' Pension Plan pushed the valuation to about $9 billion.

Leadership history was eventful. Orion Hindawi became CEO in 2016. A period of executive turnover around 2020 to 2021, including the departure of a co-CEO structure, prompted a culture and strategy reset. In 2020 the company went remote first and relocated its headquarters to Kirkland, Washington, near Seattle, while keeping its Emeryville operations center.

Dan Streetman, formerly CEO of TIBCO Software and Allvue Systems, took the CEO role in February 2023, with Orion Hindawi moving up to executive chairman. Through 2025 and 2026 the company has focused on AI-driven automation inside the XEM platform and on deepening partnerships with Microsoft, ServiceNow, PwC, and Kyndryl.

As a software company, Tanium's footprint is offices and cloud infrastructure. Its security posture is its core ethical obligation: customers grant it deep visibility into their environments, so product security, data handling, and FedRAMP-authorized government deployments carry particular weight. The company maintains standard enterprise certifications and runs a public bug bounty program.

Tanium has appeared on the Forbes Cloud 100 list for nine consecutive years, reaching the top 25. It was named Microsoft ISV Innovation Partner of the Year in 2024, appears on the CRN Security 100 and AI 100 lists, and holds Great Place to Work certification in the US, Canada, France, Japan, and the UK.

In 2017 reporting revealed that Tanium had used a California hospital's live network in sales demonstrations for years without the hospital's permission, exposing real IT infrastructure details to prospective customers. Tanium acknowledged the lapse, said it had ended the practice, and faced a wave of internal criticism over executive conduct that contributed to leadership departures the same period. No regulatory penalty resulted, and the company instituted controls restricting demo access to customer environments.
