Who Owns Freestar?

Freestar's origin story is unusually colorful for ad tech. Co-founder David Freedman launched a swimsuit calendar called Tempe12 while at Arizona State University, sold its ad space to local businesses, and expanded it to 21 colleges. In 2008 Chris Stark joined, taught himself to code, and the pair began scaling the calendar's online ad operation, then launched a consultancy called DigitalMGMT to help other publishers.

In 2014 they raised about a million dollars and spent most of it acquiring nine small websites, intending to juice revenue and flip them. The play failed as an investment but generated something more valuable: hands-on expertise in publisher ad operations. That pivot produced Freestar in 2015, a managed service that took ad operations off publishers' plates using header bidding and yield optimization.

Growth was extraordinary. Revenue climbed 36,680 percent over three years, earning Freestar the number one spot on the 2019 Inc. 5000 as America's fastest-growing private company. A private equity round in January 2021 funded expansion, and the company built out an engineering organization of 60-plus people plus yield, demand, and strategy teams.

By its tenth anniversary in 2025 Freestar employed roughly 200 people across 15 countries, held leadership-tier Prebid.org membership with a board seat, and was marketing a "publisher operating system" combining managed service with enterprise technology. Its Freestar Intelligence Suite applies data from billions of monthly impressions to yield optimization, and the company has leaned into AI-era tooling including ad-block recovery evaluation and identity testing for clients.
