Monetization and retention can seem like the opposite ends of a continuum ... a zero-sum game where focusing on monetization kills retention.

Not necessarily, says AppLike CEO Jonas Thiemann. AdJoe, one of their brands, has a unique ad placement that earns players money for installing and playing games they're interested in ... including the game they saw the ad in.

He says it's the perfect balancing of incentives between users, publishers, and advertisers, and that's why 80 out of the top 100 grossing apps on Android are using AdJoe, users are making $20-20 a month, and some publishers are taking home six-figure paydays daily.
