SSP Comparison

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

Comparing a publisher-first web SSP against a large-scale enterprise programmatic platform for digital publisher monetization.

Magnite is one of the largest independent SSPs, formed through the merger of Rubicon Project and Telaria in 2020, with subsequent acquisitions of SpotX and SpringServe adding CTV capabilities. Magnite operates at significant scale across desktop, mobile, video, and CTV advertising.

Magnite's strength is its scale and CTV inventory depth, serving major streaming platforms and large media companies. Their platform emphasizes supply path transparency and curated deals alongside traditional open auction programmatic.

Stellor Media focuses specifically on web publisher monetization — display, video, and native for digital content publishers. Our publisher-first approach emphasizes dedicated account management, rapid onboarding, and optimization focused on maximizing individual publisher revenue rather than platform volume.

Note: Magnite information is based on publicly available information including their investor relations materials and public documentation. Specific terms may change.
