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 don't have a fair system for compensating communities harmed by decades of industrial pollution.

open Global / Unspecified, Global

Some communities have lived with contaminated air, water, or soil for generations due to nearby industrial activity, with little formal compensation or cleanup. Establishing fair, enforceable accountability remains a persistent governance gap.

We haven't solved how to prevent childhood malnutrition in regions affected by conflict or drought.

open Global / Unspecified, Global

Malnutrition during early childhood can cause lifelong developmental harm, and crises like war or drought regularly disrupt food access for vulnerable children. Building more resilient food delivery systems in crisis zones remains urgently unresolved.

We can't yet fully explain the biological causes behind chronic fatigue syndrome.

open Global / Unspecified, Global

Chronic fatigue syndrome leaves patients severely limited in daily function, yet its underlying biological cause remains poorly understood and often dismissed. Without a clear cause, effective treatment remains extremely difficult to develop.

We don't have a scalable way to detect skin cancer early using simple, affordable tools.

open Global / Unspecified, Global

We haven't found a way to prevent the spread of drug-resistant tuberculosis in poorer countries.

open Global / Unspecified, Global

Tuberculosis remains a major killer in some regions, and drug-resistant strains are becoming harder and more expensive to treat. Slowing this resistance requires both better medicine access and improved treatment adherence support.

We don't have a reliable way to predict and prevent postpartum depression before it develops.

Postpartum depression affects many new parents, often going undiagnosed until it significantly affects their wellbeing and their child's early development. Better early prediction could allow support to begin before symptoms take hold.

We don't have a cure for most rare genetic diseases affecting small patient populations.

open United States, North America

Because rare diseases affect few patients, there's often little financial incentive for researchers or companies to develop treatments. Thousands of rare conditions remain effectively untreated as a direct result.

Once the tiny hair cells in the inner ear are damaged, human bodies can't naturally regrow them, making most hearing loss permanent. Cell regeneration therapies show early promise but remain far from mainstream treatment.
