Built for publishers who care about their pages

One tag that monetizes without taking over: lightweight, transparent, and run by people you can talk to.

The Keystone platform

Placements by country and device, preview on your own pages, and approval before anything goes live. Your Babel team runs it for you.

7 ad formats

Each format reaches a different reader moment, from the first scroll to the end of the article. They coordinate on the page, so they never compete for the same space.
