What FreedomSponsors is
FreedomSponsors is a platform for supporting free/libre software projects through microcrowdfunding – that is, crowdfunding individual open source project’s issues.
The issue crowdfunding system is similar to JIRA’s voting system, but the votes come with a “money offer” attached. Anyone can go and place a bounty on an specific issue they need. If more people also need it solved they can “chip in” and the bounties will add up. Developers then can resolve the issues and claim their prizes – the sponsors are notified and pay the developers once the solution is verified.
