AngelList

Chartboost’s is a publisher platform that provides multiple services:

1) Cross-promotion for their own users - so publishers can drive users playing one of their game titles and to try another.

2) Direct Deals Marketplace - where publishers can cut deals with other publishers to cross-promote each other’s titles skipping the 50% rev-share ad networks would take.

3) Network to monetize unused “remnant” inventory and make some extra cash.
