As we enter our second decade at Freestar, I’ve been reflecting on our journey and on how the current AI Age is reshaping the publisher ecosystem. Freestar was founded with a focus on optimizing header bidding and monetization, but over the last ten years, we’ve built something so much bigger. We realized that solving for revenue alone isn’t enough. Publishers need a central system to manage all of their ad tech and publishing solutions, not just a collection of fragmented, non-integrated tools and vendors.
That’s why I’m excited to formally introduce pubOS, the industry’s most comprehensive publisher toolkit.
This isn’t just a new product launch; it’s the unification of the ecosystem we’ve been building all along. Instead of managing dozens of separate vendors, our single, easy-to-use platform gives publishers access to an entire ecosystem of integrated solutions.
So, what is pubOS? It’s an all-encompassing system built in three seamless layers:

- At the Core is Freestar’s Award-Winning Technology: The engine that powers your business, anchored by our proprietary monetization technology. It’s our custom Prebid wrapper, AI-driven yield optimization engine, and unified analytics, with multi-platform support for desktop, mobile web, and in-app.
- Wrapped around that is The Marketplace of Integrated Solutions: One of the biggest challenges for publishers is vendor fatigue. The time and energy necessary to assess, negotiate and then test new partners is overwhelming for most publishers. pubOS eliminates that. Through our single integration, you gain access to an entire marketplace of best-in-class, third-party solutions for everything from ad block recovery and identity to AI content licensing and advanced analytics.
- The Outermost Layer is Our Signature White-Glove Service: Technology and tools are only as good as the team behind them. This layer is our team of dedicated experts. Customer Success Managers, Yield Strategists, and Support Engineers who act as a true extension of your own teams, providing the strategic guidance and proactive support that defines a Freestar partnership.
With one simple implementation, pubOS gives publishers a world-class foundation to build on. What happens on top of that—the tools you plug in, the services you leverage—is a continuum tailored to you. We provide endless options to optimize your business.
“We used to spend more time managing our ad tech stack than improving our content,” said Even Scharning, founder of Time.is. “Since working with Freestar, and now with pubOS, we have access to the same caliber of technology and strategic support that the biggest media companies use, without needing to build a 20-person ad ops team. It’s the kind of partnership that lets a publisher like us punch above our weight.”
We’re thrilled to continue expanding our ecosystem and are excited to launch our pubOS Partner Page, where you can see our ever-expanding list of integrated partners.
I am incredibly proud to partner with so many of the world’s most trusted publishers, and our commitment to building a better future for digital media has never been stronger. As always, we’ll continue to lead with one simple principle: #PublisherFirst.
