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 lack precise constraints on the habitability of subsurface ocean worlds.

open Global / Unspecified, Global

Moons like Europa and Enceladus may harbor oceans beneath ice, but we do not know their chemical gradients or energy sources. Cryobot and plume-sampling missions could test for conditions suitable for life.
