OtterSource
A marketplace that funds open source work.

The problem
Open source powers the modern internet. Critical infrastructure (the libraries, frameworks, and tools that companies build on) is maintained by volunteers working in their spare time. When an important issue sits unfixed for months, the whole ecosystem suffers. The companies and developers whose businesses depend on this work rarely contribute back financially.
How OtterSource works
Anyone (a company, a developer, or just a user who cares) can post a time-limited bounty on a public GitHub issue. Developers see these bounties alongside the issue and are incentivised to solve them. When the issue is closed and the solution is merged, the bounty is paid to the contributor. No middleman friction, no complicated governance.
Why time-limited?
Open bounty systems often stall: money sits unclaimed, priorities shift, and the original poster loses interest. Time-limited rewards create urgency and clear signals about what matters right now. If a bounty expires unclaimed, the poster can renew it, increase it, or let it go. Either way, the signal is honest.
Current status
The business model is being redesigned around a service-provider structure: OtterSource will sell bounty resolution as a service rather than hold client funds in escrow. Buyers will purchase non-refundable credits that convert to revenue only once a bounty is completed, and developers and maintainers will be paid directly in cash via Stripe Connect. Because no funds will ever be held on anyone else's behalf, the model avoids the EU payment-institution licensing (PSD2/EMD2) a traditional escrow-based marketplace would need.
