At Calldorado we break down the two main barriers to growth in the app economy.

By offering our advertising SDK to app owners free of charge, with our patented technology, we enable them to generate revenue and put their app features into the spotlight with every call a user makes or receives.

We are headquartered in Copenhagen, but we are truly global.Our customers are anywhere an Android app is being developed. That means everywhere.
