World Solve — A living repository of problems worth solving.

What World Solve is

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 builders Skip the search for a problem worth your time. Browse a vetted, growing list and start where the gap is real.

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.

We still haven't proven whether it's possible to guarantee a solution exists for every well-posed system of nonlinear equations, even without finding it explicitly.

While many specific systems have proven solutions, a complete general guarantee across every well-posed nonlinear system remains one of mathematics' harder open questions. This affects fields ranging from physics to engineering that rely on such systems.
