Key points from Digiday’s report

  • Stagwell's acquisition of Freestar may increase its influence across the advertising supply chain.
  • The deal includes Freestar's technology and services business, which works with over 1,000 publishers.
  • The acquisition is part of Stagwell's investment thesis, which aims to reduce reliance on outside vendors and increase visibility into transaction costs.
  • The outcome of the acquisition for advertisers and publishers is uncertain and will depend on various factors.
  • The acquisition raises questions about transparency and how Stagwell will handle transactions involving its own businesses.

Stagwell, a holding company, has acquired Freestar, a firm that helps publishers manage their advertising inventory. According to Digiday, this deal may extend Stagwell's influence across the advertising supply chain.

The acquisition includes Freestar's technology and services business, which works with over 1,000 publishers. These publishers generate a large volume of ad requests, making Freestar a significant player in the supply-side operation.

Stagwell plans to use Freestar's technology to support its own portfolio of properties, including a travel publisher and an airport television network. This may allow these properties to increase their programmatic sales and potentially gain access to more advertisers.

The acquisition is part of Stagwell's investment thesis, which aims to reduce reliance on outside vendors and increase visibility into transaction costs. By owning more of the infrastructure supporting automated buying, Stagwell may be able to retain revenue that was previously earned by intermediaries.

However, it is unclear whether this acquisition will directly benefit advertisers or publishers. The outcome will depend on various factors, including pricing, contractual terms, and how Stagwell handles transactions involving its own businesses.

For advertisers, the key questions concern inventory selection and incentives. They will want to know whether Stagwell's buying teams can demonstrate why a particular publisher was selected and whether clients are informed when Stagwell earns revenue from both buying services and publisher monetization.

Publishers also have questions about the acquisition, including whether Freestar will continue to prioritize their revenue and how access to Stagwell's demand will work. They will want to know whether they need to adopt additional group services to gain commercial advantages.
