More details will be revealed after the nice folks I've talked to are keen to take off this idea together (else it will be my next solo project after TripLogger).
How does it work?
1. For developers - Get some funding before starting work on your next app. Get validation of features/ideas to develop (save time and reduce risk).
2. For investors-wannabe - Earn money with your ideas. 'Hedge' the risks by spreading your investments among different developers and ideas.
