System1

System1 operates a vertically integrated adtech and digital media model. It acquires high-intent traffic through programmatic media buying, routes that demand through its owned and partner inventory, and monetises user intent via advertising, affiliate economics and downstream conversion revenue. The owned media portfolio strengthens the model by supplying proprietary traffic, data signals and inventory, while the consent platform supports privacy-compliant execution for publishers.

System1 is a US-listed digital advertising and customer acquisition company that combines a proprietary demand-side buying platform with a portfolio of owned consumer web properties. Its core platform, RAMP, uses intent data, auctioning technology and real-time optimisation to acquire users for advertisers and performance marketers across channels including web, search, social and CTV. In parallel, the company owns and operates consumer destinations such as Startpage, MapQuest, HowStuffWorks, Answers and CouponFollow, which provide proprietary traffic and monetisable ad inventory.

The business makes money through a hybrid model: buying media and monetising acquired traffic at a margin, earning advertising revenue from owned-and-operated properties, and capturing affiliate or partner revenue on commerce-intent traffic. It also offers a consent management product for publishers, supporting privacy-compliant monetisation within its broader advertising ecosystem. Customers are primarily advertisers, performance marketers, brands and publishers rather than end consumers, even though many of its media assets are consumer-facing.
