Stagwell today announced the acquisition of Freestar, an Arizona company that runs programmatic advertising for digital publishers including Boston Globe Media, Fortune Media, Legacy and Enthusiast Gaming. The deal moves a business that works for the sellers of advertising space into a marketing group whose agencies work for the brands buying it. Neither company disclosed a price.

Freestar will sit within Stagwell's Owned Media offering, part of the larger Media and Commerce segment, according to the announcement distributed through ACCESS Newswire from New York. Stagwell, listed on Nasdaq under the ticker STGW, describes itself as "the global challenger network transforming marketing through AI." Needham & Company served as exclusive financial advisor to Freestar. No adviser is named for Stagwell, and the release gives no purchase price, no deal structure and no figure for Freestar's own revenue.

In Short

Stagwell, a large group of marketing agencies, has bought Freestar, a company that helps websites like Fortune earn money by selling their ad space to advertisers. This matters because Stagwell's agencies buy ads for brands, so one owner now sits on both the buying side and the selling side of some ad deals. Freestar keeps working for its publishers, but nobody has said how much Stagwell paid or how data will move between the two sides.

What Freestar does

David Freedman founded Freestar in 2015, and the company is headquartered in Scottsdale, Arizona. Its work sits between a publisher's pages and the exchanges that bid for space on them. Freestar's own website lists two header bidding services, Fully Managed and Flex, alongside technology for web, AMP and app inventory. It describes an approach built on "the perfect mix of client-side and server-side demand partners," intended to keep latency down.

Those choices are the practical work of header bidding. A publisher offers each impression to several exchanges at once before its ad server picks a winner, and every additional bidder called from the browser slows the page. Which partners to call, from where, and how long to wait for them are decisions many publishers hand to an outside firm. Freestar is one of those firms.

Its product is pubOS, which the release calls Freestar's "proprietary Publisher Operating System." According to Stagwell, pubOS combines "enterprise-grade technology, an integrated marketplace of partner offerings, and high-touch customer service." The boilerplate at the foot of the release swaps "high-touch" for "white-glove" and says the purpose is to help digital publishers "maximize revenue and navigate the AI Age." Neither the release nor Freestar's two company pages give a technical specification for pubOS.

On LinkedIn, Freestar says it "engineers cutting-edge monetization solutions for websites and apps," so that site and app owners can "seamlessly maximize revenue while freeing themselves of the hassles of ad operations." The client list in the release runs "from news to gaming to utilities." The company's stated values, on its Who We Are page, are "Publisher First," "Above and Beyond" and "We Not Me."

Two claims carry the weight

The release leans on two figures. The first is cumulative. Over the past decade, according to Stagwell, Freestar "has driven over $1 billion in revenue for publishers." That is money that reached publishers, not revenue Freestar kept, and the release does not say what share Freestar retained or how the total was spread across the years. Divided evenly over ten years, it would average a little more than $100 million a year, a PPC Land calculation that the release's lack of an annual breakdown makes rough at best.

The second is a ranking. Freestar "manages more premium Jounce Media Bellwether publishers than any other publisher services partner," according to the release. Jounce is a New York research company that grades the routes advertising money takes from buyers to publishers, and Bellwether is its top label. It covers the most direct paths run by a list of 100 sellers that Jounce reviews by hand. Jounce's December 2025 report named 100 Bellwether portfolios for 2026, and Playwire, one of them, said the list captured about 70% of DSP spend. The release does not say how many Bellwether publishers Freestar manages, or on which edition of the list the ranking rests.

Freestar has appeared on the Inc. 5000 list of fast-growing private US companies for seven consecutive years, taking the number one spot in 2019, according to the release. It also cites AdWeek's AI Tool of the Year and the Titan Business Awards Customer Service Team of the Year, without giving years for either.

A remote team of about 195

Freestar's Who We Are page lists "195+ Team Members," located in more than 10 countries and speaking more than 10 languages. The company calls itself fully remote; its LinkedIn page states "We are 100% remote" and lists company offsites, a home office stipend and flexible working location as benefits.

LinkedIn's own data tells a slightly different story about size. The company page places Freestar in the 201-500 employee band, a range companies select themselves, while counting 195 associated members. LinkedIn's hiring insights for Freestar, shown on a listing for a remote Director, Publisher Sales role in the United States, put employee numbers down 15% on a chart running from October 2024 to October 2026. The line drifts lower across most of that period and dips again in the final weeks. LinkedIn draws these figures from members' profiles rather than company payroll, so they track people who list Freestar as their employer.

The Who We Are page names 17 people on the leadership team. Kurt Donnell is chief executive, Freedman is listed as founder, Christy Rosensteel is general counsel and CPO, and Matthew Wells is chief financial officer. Executive vice presidents cover growth and publisher development, engineering and operations, with senior vice presidents for demand and product engineering.

Where Freestar lands inside Stagwell

According to the release, Freestar "will further strengthen Stagwell's Owned Media offering as the larger Media and Commerce segment continues to expand its media capabilities and offerings for clients." Freestar's customers, in turn, "will have more direct access to advertisers and tools, providing better outcomes for both the buy and sell side of the market."

The integration plan is described in four parts: expanding the Owned Media portfolio, "enhancing audience intelligence," developing "a more streamlined supply path," and a layer of agentic decisioning. A supply path is the chain of exchanges and resellers a bid request passes through between a publisher's inventory and a buyer. The release puts the AI piece this way: "Through agentic decisioning, powered by the Stagwell AI Media Machine, we will deliver quality inventory to right audiences, while at the same time ensuring most efficient path to activation."

That sentence connects Freestar to a product line Stagwell has built through 2026. Stagwell launched The Machine, an agentic marketing operating system, in January 2026, and was the pilot partner when The Trade Desk shipped Koa Agents on April 22. On June 19 it announced The Media Machine, extending that system into agentic media buying. Today's release calls it the "Stagwell AI Media Machine." It does not explain how agentic decisioning would use Freestar's inventory, or whether data from Freestar's publishers would feed the "audience intelligence" it mentions.

Stagwell has bought its way into technology before. It acquired Apollo Program, an AI software platform, in July 2022, and Maru Group and Epicenter Experience in October 2022; Epicenter's product, The People Platform, was renamed Numetrix on September 1 without a disclosed change to the product. In results covered by PPC Land in August, Stagwell's revenue rose 10% and organic revenue 8%, with its digital transformation unit growing 12%.

The release also ties the deal to Stagwell's Future of News initiative, which it describes as "bringing together a coalition of publishers, marketers, journalists, and brand leaders to drive impactful change." Two of the four Freestar clients it names, Boston Globe Media and Fortune Media, are news publishers.

Ben Berentson, chief executive of Owned Media at Stagwell, framed the purchase around publishers. "Publishers are essential to a healthy media ecosystem, and we believe their long-term success is critical to the future of our industry," he said, according to the release. "Freestar has built an exceptional global business helping publishers increase revenue and improve operational efficiency in a complex programmatic landscape. Together, we'll continue investing in that mission while bringing new capabilities to support their growth and their clients' success."

Buyer and seller under one owner

Donnell's statement goes to the tension at the centre of the deal. "Freestar has always been focused on helping publishers unlock more value from their businesses," he said, according to the release. "The best outcomes happen when advertisers know exactly what they're buying, and publishers are rewarded for the quality they deliver. Stagwell understands that. Joining them lets us offer publishers new capabilities, while staying true to the publisher-first approach that has always been our north star."

Freestar's executives have taken the publisher side of the transparency argument before. When Prebid introduced bidder-specific transaction IDs in August 2025, Heather Carver, Freestar's chief revenue officer, argued that the IDs could be linked across SSPs the way a device graph links devices, letting buyers shift spend to cheaper routes and compress publisher yield, and that many publishers wanted to limit them in the open market. In February 2026, Donnell told AdExchanger Talks that conditions were extremely tough for publishers, while arguing that a move toward greater transparency should benefit publishers that do not game auctions.

That position now sits inside a group whose agencies buy media for brands. The release presents this as good for both sides of the market. It does not describe any separation between Freestar and Stagwell's buying operations, any limits on how publisher data may be used, or any commitment to treat buyers outside Stagwell on equal terms.

Another holding company deal this year drew conditions on these points. Publicis Groupe agreed in May to buy LiveRamp for about $2.5 billion, and on October 19 the Federal Trade Commission proposed a consent order that would require LiveRamp to serve all US customers on fair, reasonable and non-discriminatory terms, would bar Publicis from using LiveRamp customer data to build or train its products, including AI, without explicit authorization, and would run for five years. LiveRamp is a data collaboration platform used across the industry, and Freestar is a publisher monetization partner, so the comparison is about structure rather than scale. Today's release mentions no regulatory review.

Why the deal matters for publishers and buyers

Publishers have watched their traffic base shift. Search fell to 12% of North American publisher pageviews in the third quarter of 2026, from 21% a year earlier, in Chartbeat data. Earlier Chartbeat figures, reported in March, showed small publishers losing 60% of search referral traffic over two years. In July, Raptive rolled out Apex, an enterprise offering that pairs its monetization technology with a team embedded alongside a publisher's own staff.

The publisher services firms Freestar competes with have been adjusting their terms and products. Raptive lowered its entry threshold from 100,000 to 25,000 monthly pageviews, and Mediavine's main platform asks for at least $5,000 in annual ad revenue. In April, Mediavine made audience segments from more than 18,000 publishers available through Index Marketplaces. LinkedIn lists Raptive, Mediavine and Playwire among the pages viewed alongside Freestar's; their pages show 148,190, 76,227 and 49,880 followers respectively, against about 12,000 for Freestar.

Freestar's own footprint has grown in industry data. In DataBeat figures from February 2026, Freestar led the emerging tier of ads.txt growth. In DataBeat data published at the end of September, Freestar added 114 direct publisher domains, fourth among the emerging group of SSPs ranked 151 to 500 by direct connections.

For buyers, the release points to a shorter route from Stagwell's AI buying tools to Freestar inventory, described as the "most efficient path to activation." Supply path work usually removes intermediaries between a buyer and a publisher. Here the buyer's agency group owns one of the intermediaries. Will Stagwell clients' campaigns be steered toward Freestar publishers, and on what terms will other buyers reach the same inventory? The release does not say. For publishers, the promise is "more direct access to advertisers and tools." How much of Stagwell's client spending that represents is not stated.

What the announcement leaves open

Several points remain undisclosed. The release gives no purchase price, no deal structure and no revenue or margin figures for Freestar. It does not say whether data from Freestar's publishers will be used by Stagwell's audience products or AI systems, or under what consent. It names no integration timeline and none of the Stagwell owned media properties that Freestar will sit alongside. The Bellwether ranking carries no count and no date, and the industry awards carry no years.

Freestar's LinkedIn presence, meanwhile, shows a smaller company than two years ago, still hiring for publisher sales. The 15% decline on LinkedIn's chart predates today's announcement, and no source connects it to the deal.
