Affinity

Affinity creates value by operating both transaction-based adtech products and recurring software tools across the digital advertising supply chain. On the demand side, it helps advertisers and agencies buy and optimise campaigns across non-walled-garden inventory. On the supply side, it helps publishers, OEMs, and platform partners monetise traffic through ad serving, bespoke formats, affiliate automation, and engagement-driven data capture. This enables the company to monetise multiple points in the advertising and commerce value chain rather than relying on a single product line.

Affinity is an ad technology holding company operating a portfolio of products for advertisers, publishers, affiliate publishers, and media partners. Its offering spans media monetisation infrastructure, ad network inventory, demand-side campaign execution, affiliate link automation, and polling-based first-party data tools. The company appears to make money through a combination of media margins, revenue shares, affiliate commissions, and software subscription or usage fees.

Its customers are businesses rather than consumers: brands, agencies, digital publishers, media companies, OEMs, browser partners, and affiliate publishers. Affinity has expanded its stack through acquisitions including Opinary in 2023 and Affilizz in 2025, using M&A to deepen publisher monetisation, first-party data capture, and affiliate commerce capabilities.
