Welcome to AI.C

In 2009 we founded our first app business and quickly turned it into a revenue generating and profitable venture. We cracked the nut when it came to driving app usage and effectively monetizing our apps. With the launch of Calldorado ApS in 2016, we opened up our advertising technology for third party apps to do the same.

With 80 in-house apps, and thousands of third-party apps using our technology, we decided it was time to address the fundamental problem all app publishers face, namely access to capital for driving growth.

Without funds to promote their apps, and grow their user base, apps end up going nowhere. With more than 3 million apps on Google Play alone, the market is over-crowded. Top rankings are taken by the big-name apps, and discoverability is a huge challenge. Counting on organic downloads or on being featured in the stores is not a viable way forward.

In the app world success boils down to app publishers having significant user acquisition budgets.
It was out of this realization that AppInvestor.Club was born.

We have seen many attempts at creating app funding models, but most of them have failed because they lacked the ability to generate attractive returns for investors, and this is where AppInvestor.Club disrupts the convention.

The underlying Calldorado monetization technology required for listing apps on AppInvestor.Club drives fast ROI. We have invested large amounts in user acquisition ourselves, and we know it pays off when apps monetize with Calldorado.

By connecting publishers and investors in a unique and easy way, and using our multi-award winning monetization platform to drive returns, AppInvestor.Club is making success in the mobile arena possible for app publisher and investors alike.

We look forward to welcoming you to the Club.
