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 fully understand why some people age much slower than others.

open Global / Unspecified, Global

Some people reach old age with sharp minds and healthy bodies, while others decline much earlier, and genetics only explains part of it. Understanding this gap could extend healthy years of life for far more people.

open Global / Unspecified, Global

Millions of people with chronic pain are stuck choosing between inadequate relief or medications that carry serious addiction risk. A safer, equally effective alternative remains one of medicine's most requested breakthroughs.

We can't stop antibiotic-resistant bacteria from spreading faster than we develop new antibiotics.

We don't have affordable cancer screening that catches every type early enough to treat well.

open Global / Unspecified, Global

Some cancers are caught early and treated successfully, while others are found too late simply because no cheap, accurate screening exists for them. Broader early detection could save far more lives than treatment breakthroughs alone.

We can't grow replacement organs that a patient's body won't reject.

open Global / Unspecified, Global

Organ transplants still require lifelong drugs to stop the body from attacking the new organ, and many patients never get a match at all. Lab-grown organs from a patient's own cells could eliminate both problems.

We don't have a universal vaccine that protects against all strains of the flu.

open United States, North America

The flu virus mutates constantly, forcing a new vaccine guess every year that sometimes misses the mark. A universal flu vaccine could end this annual guessing game and prevent thousands of deaths.

We can't cure most autoimmune diseases, only manage their symptoms.

open Global / Unspecified, Global

Conditions like lupus, rheumatoid arthritis, and multiple sclerosis occur when the body attacks itself, and current treatments mostly suppress symptoms rather than fix the root cause. Millions live with lifelong management instead of a real cure.

We don't have enough clean water infrastructure to serve growing cities in dry regions.

open Global / Unspecified, Global

Many fast-growing cities in arid regions are outpacing the water systems built to serve them, leading to shortages and rationing. Solving this needs both new infrastructure and smarter long-term water planning.

We can't stop rivers and groundwater from being drained faster than they refill.

Many major rivers and aquifers are being pumped or diverted faster than rainfall can replenish them, threatening long-term water security. Without better management, some regions may simply run out of accessible fresh water.

We haven't built cities that can absorb floodwater instead of being destroyed by it.

open Global / Unspecified, Global

Paved surfaces send rainwater rushing into drains that quickly overflow during storms, instead of letting it soak into the ground. Cities designed to absorb water naturally would suffer far less flood damage.

We can't track and reduce methane leaks from oil and gas infrastructure worldwide.

open Global / Unspecified, Global

Methane is a far more potent greenhouse gas than carbon dioxide in the short term, and much of it leaks unnoticed from pipelines and wells. Better detection and faster repairs could meaningfully slow near-term warming.

We haven't found an affordable substitute for cement that doesn't release as much carbon.

Cement production alone accounts for a huge share of global carbon emissions, yet it remains central to nearly all construction. A low-carbon alternative that's just as strong and cheap would be one of climate policy's biggest wins.
