Our Story
Founded in 2016 and headquartered in Birmingham, UK, Redbrain works with over 5,000 retailers and brands across 23 countries in Europe, the United States and Australia, including eBay, B&Q, Boden, The LEGO Group and Secret Sales. In 2025 Redbrain delivered £1.25 billion in incremental sales for its retail partners from 634 million clicks. Redbrain is Europe's largest CPA (pay-on-sale) CSS partner, a Google Premium CSS Partner and a Google CSS Spotlight winner in 2024 and 2025.
What Sets Us Apart
Europe's largest pay-on-sale CSS partner
Genie Shopping, Shoparize and Kelkoo also offer pay-on-sale CSS models. No other CPA partner funds the clicks and delivers more than £1 billion a year in incremental sales; Redbrain delivered £1.25 billion in 2025 across over 5,000 retailers.Incrementality measured, not assumed
Measured across Redbrain's partner base in 2025, retailers' own campaigns outranked Redbrain in the Google Shopping carousel 91% of the time, and 44% of Redbrain's activity sat outside partners' existing marketing.Redbrain pays for the clicks
Redbrain funds every Shopping ad click from its own budget and is paid only when a click becomes a sale, so the retailer carries no click cost. Subscription CSS partners such as Adstrong host the retailer's own campaigns for a monthly fee, and the retailer still pays Google for every click.
