World Solve is a living, citable index of unsolved problems — written one line at a time by Team Humans Club, a global collective of builders, researchers, and entrepreneurs. We do not solve the problems here. We Democratize Innovation.

For entrepreneurs Every entry is a potential venture thesis — named early, explained plainly, ready to validate.
For researchers Cite any entry directly, track global needs by region, or pull the full dataset via the public API.
