Somewhere in these 1,000 unsolved problems is the business you're meant to build.

Ideas are guesses. Problems are knowledge. Zerosolved is a library of 1,000 real, unsolved problems people face every day — scored, argued against, and verified by a human being, one a day. Find yours. The six weeks of homework you were about to skip is already done.

section 01 · the difference

“Can't I just ask ChatGPT for startup problems?”

You can. You'll get something that looks like this in thirty seconds — same headings, same confidence. Here's what it will never contain.

a chat answera zerosolved case file
sourcesPlausible claims, no links you can open.Every claim links to a source a human opened and read.
demandVague adjectives — “growing”, “huge”, “underserved”.Counted complaints, dated volumes, upper-bound vendor stats.
field dataNone. It has never spoken to anyone.Paraphrased voices from the people living the problem.
competitionNo idea. It cannot see this month.Competitor radar plus a builder's registry of who claimed what.
honestyConfident about everything, including the wrong things.Counter-evidence, limitations and amber flags kept visible.

the difference, in one line

A model can imitate our format. It cannot produce a single number in our case files.

Every figure here was read off a source by a person, dated, and graded — or tagged [modeled] where it's an estimate. The pass buys the machine that does that every morning, not the format around it.

section 02 · the product, live

Don't take the tour. Touch the exhibit.

Below is a real slice of a real case file, rendered by the same components the case page uses — the same dials, the same funnel, the same graded objection.

The live slice is loading from the library — one moment.

section 03 · the machine

Why you can trust the seal

A machine finds the pain. A human signs the proof. Here is exactly what happens between those two things.

overnight · automatic

The trackers never sleep

Crawlers read forums, reviews, support threads and trade groups through the night, and queue what looks like real, repeated pain.

07:00 · human

One person opens every link

Nothing gets the seal until a human has opened every source. Anything unverifiable stays visibly “in research” instead of quietly shipping.

always on · automatic

Cases stay alive

Competitor radar, complaint velocity and tripwires keep running after publication — watchers are alerted the same day something moves.

you · in control

You steer what's next

Watch any of the 1,000 problems. The most-watched go to the front of the verification queue, so the library follows real demand.

section 04 · founder note

Why this exists — and why some of our dials are amber.

I spent a year building something nobody needed. Not a bad year of work — a bad year of guessing. I had an idea I loved, and I protected it from every fact that might have killed it. What I needed, and never had, was a shelf of problems that were already proven to hurt someone, with the sources attached.

That's what this is. One thousand real problems, and case files that argue against themselves: amber dials where the evidence is thin, counter-arguments in the same room as the opportunity, kill conditions written before the playbook. If a problem is a bad bet for you, the file says so.

Honesty costs sales here — a visible “in research” counter looks worse than a full library, and telling you to walk away sells nothing. That's the point. Every case that carries the seal, I opened every link myself that morning, with coffee, in France. If that's the kind of research you want under your next year of work — welcome.
