WHO WE SERVE
We Connect Premium Publishers with Advertisers
Colossus SSP isn’t just another ad tech platform -- we’re a partner. We provide hands-on support, ensuring every client gets the expertise and attention needed to grow. We work with:

What's an SSP and How Does it Work?
An SSP is a technology platform that automates the buying and selling of digital advertising inventory (IAB). Publishers use SSPs such as Colossus to maximize their revenue by offering their inventory to multiple advertisers.
For their part, advertisers gain access to premium, brand-safe placements through programmatic auctions. Colossus SSP connects both sides, ensuring efficient transactions, transparent pricing, and AI-driven optimization for better performance.
Thanks to the efficiencies, programmatic advertising continues to grow year after year.
Curated Deals: Smarter Inventory, Easier Buying
Colossus SSP’s curated deals provide advertisers with pre-packaged audience segments, eliminating the complexity of the open market. Buyers can instantly activate premium, brand-safe inventory by inserting a deal ID into their DSP, ensuring efficiency and precision targeting.
For publishers, inclusion in a curated deal means your inventory is showcased to premium, high-intent buyers who prioritize quality placements. This, in turn, will increase demand, improve fill rates, and drive higher yields compared to the open market.
