welcome to sonobi

We bring publishers and marketers together via a single premium buying and selling platform built to enable publishers to manage their programmatic and endemic advertisers and marketers to buy premium inventory in a brand-safe, transparent environment.

Our products

Sonobi has built and refined the only proprietary publisher-focused technology stack. We call it our Publisher Operating System. We have tools available for publisher clients of all sizes that will help build a scalable revenue platform for you to drive growth.



Our proprietary ad server enables publishers to easily and effectively monetize their web sites. Utilizing a custom framework, Siteline provides a combination ad server and RTB marketplace where our premium buyers compete with your own advertisers for every impression.


yield optimization

Sonobi makes ad yield optimization easy. With the robust protections and controls of the Sonobi platform, you can command great rates and serve relevant ads. Optimization with Sonobi means ad revenue increases—typically 50 to 300% higher than traditional ad networks or direct selling.


programmatic guaranteed

Bring your programmatic revenue strategy out of the dark ages. Programmatic monetization is no longer synonymous with low CPMs. By utilizing Sonobi’s custom framework, gain access to premium buyers willing to pay premium CPMs for your inventory. This product is currently limited to selected premium publishers. Contact Sonobi today to find out if you qualify.
