SSP Comparison

Stellor Media vs. Equativ — Which SSP is Right for Your Site?

Publisher-first US web SSP versus a global EU-rooted independent ad platform — which fits your site?

Equativ (formerly Smart AdServer) is a global independent advertising platform with deep European roots and a footprint across web, video, and CTV inventory. They offer both ad serving and SSP capabilities and have grown via several acquisitions.

Stellor Media is a US-focused publisher-first web SSP for mid-market publishers, with managed onboarding and dedicated account management. We do not currently offer ad serving or CTV-specific products.

Larger publishers with CTV / video inventory looking for a multi-channel platform

Frequently Asked Questions

Can I run Stellor and Equativ together?

Yes. Both run inside Prebid.js and bid in the same auction. Many publishers add Stellor on top of an existing global SSP to lift US demand.

Does Stellor offer ad serving?

No. Stellor focuses purely on the SSP/yield layer. Most of our publishers run Google Ad Manager as their ad server and use Stellor for header-bidding demand.
