Stagwell Calls Freestar "Publisher-First." Stagwell Now Owns Both Ends of the Bid.

On Oct. 26, Stagwell bought Freestar, the Scottsdale company that runs programmatic sales for more than 1,000 publishers, including Boston Globe Media and Fortune. Terms weren't disclosed. Freestar's CEO promised a "publisher-first approach." Then Ben Berentson, who runs Stagwell Owned Media, told AdExchanger the network will help Stagwell improve its own principal media buying strategy.

Here is why that sentence matters. Freestar's job is to get each impression the highest price. A Stagwell agency's job is to buy it at the lowest price. In principal media, the agency buys inventory itself and resells it to clients at a markup the client doesn't see broken out. So when a Stagwell agency bids on a Freestar publisher, Stagwell is the seller, the buyer and possibly the reseller in the middle. The announcement describes no firewall on who can see Freestar's bid data, floors and yield.

Nick Manning got three yes-or-no questions and gave one answer: "Of course." Conflict? Disclosure? Publisher opt-in? Of course. Jack Myers was more measured and no friendlier: fewer intermediaries do not by themselves prove better outcomes for advertisers or publishers, and agentic buying may automate existing conflicts rather than resolve them. Freestar finishes a year-long buildout: The Machine, a FreeWheel hookup, Stagwell Curate, and now the sell side.

Three days after the deal, Stagwell's Q3 release called it "the biggest quarter in Stagwell's history" and raised its EBITDA guidance. It did not mention Freestar. Publishers should ask for the firewall in writing. Clients should ask which of their impressions ran through a seller their own agency's parent owns.
