Redbrain

We’re the premium CSS partner for marketers obsessed with peak performance.

Since 2018, we’ve helped retailers across Europe generate billions in incremental sales – by showing up exactly where it counts: in the Shopping carousel, at the moment a customer decides to buy. In 2024 alone, we delivered over £1.2BN in extra sales.

We’re Europe’s #1 CSS partner by volume. We didn’t get there by shouting. We got there by doing. Delivering day after day for clients. Every ad we run is calibrated to your success. Every click we chase is one you might’ve missed. Every optimisation is made in real time, and sharpened over time.

We don’t chase vanity metrics. We focus on what matters: provable, repeatable, incremental growth. And we do it with an average 9X ROAS.

Great marketers never settle. Neither do we. Together, we win.
