Zerosolved is a library of 0 real, unsolved problems, each researched like a case file. Every case shows the evidence (graded sources, market size, competitors) and the honest argument against it, so you can choose what to build from facts, not a hunch.

section 03 · inside every case
From “is this pain real?” to “what do I do on Monday?” — here's exactly what you open.
The problem in plain words, who bleeds, and the Zero Score.
How hard the pain is, scored across the dials that matter.
Counted signals, paraphrased voices, and the counter-argument.
Who pays, how much it costs them, and where the money sits.
Why now — and the tripwires that would make it too late.
Segments, buying triggers, and the person who signs.
Pricing logic, unit shape, and what keeps you defensible.
Three doors in, a 48-hour test, and the kill conditions.
Radar, velocity, and alerts the day something changes.

section 05 · the difference
Whether it's for a college project, a competition, or a real business, a chatbot answers in seconds. Here's what that answer can't contain.
Plausible claims, no links you can open.
Every claim links to a source a human opened.
Vague adjectives — “growing”, “huge”, “underserved”.
Counted complaints and dated volumes.
None. It has never spoken to anyone.
Paraphrased voices from people living the problem.
No idea. It cannot see this month.
Competitor radar with dated tripwires and same-day alerts.
Confident about everything, including the wrong things.
Counter-evidence 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.
section 06 · the machine
Four stages, in order, every time — a machine finds the pain, a human signs the proof.
stage 01
overnight · automatic
Crawlers read forums, reviews and support threads through the night and count what's actually repeated. Only pain that shows up again and again enters the morning queue.
stage 02
07:00 · human
Nothing earns the seal until a human has opened every single source. A claim with no link a person checked is not a claim — it stays visibly “in research” until it has one.
stage 03
07:00 → publish · human
Each source is graded A, B or C, and a claim needs two independent source classes to stand. Vendor statistics count as an upper bound, never as fact. Estimates are published — openly tagged.
stage 04
always on · automatic
Competitor radar, complaint velocity and tripwires keep running after publication. The day a launch, funding round or pricing change moves the case, watchers hear about it.

“Who else is reading this?” — students and builders who swapped a guess for a case file.

“My final-year project is now a tool a local logistics firm wants to pilot.”
Every engineering hackathon in India has 50 teams building the same AI wrapper. Zerosolved showed me supply-chain bottlenecks with real workflow numbers — my final-year project is now a tool a local logistics firm wants to pilot.

“Zerosolved does the legwork — proving the dollar cost of an unsolved inefficiency.”
Most startup problem lists are just speculative threads. Zerosolved does the legwork — pulling from SEC filings, market reports and Statista to prove the dollar cost of an unsolved inefficiency.

“Knowing why three earlier teams failed saved our team six months of wasted sprints.”
What convinced me wasn't the problem score — it was counter-evidence and failure modes. Knowing why three earlier teams failed saved our team six months of wasted sprints.

“The unit-economics breakdowns read like private-equity diligence.”
Before you draft a pitch deck or model TAM, you need to know who suffers enough to pay on day one. The unit-economics breakdowns read like private-equity diligence.

“It helped us skip building another dashboard and solve machinery diagnostics instead.”
Our campus incubator was full of generic SaaS ideas. Zerosolved pointed at the raw maintenance friction in agricultural fleet repairs with real ticket data — we built our prototype around actual sensor failures instead of guessing.

“The regulatory citations showed where clinic staff actually lose hours.”
In healthtech hackathons everybody pitches patient apps that clinics never buy. Zerosolved showed the compliance and records-audit bottlenecks where budget is already allocated, and turned our semester project into a working clinical tool.

section 10 · founder note
“Why should I believe you?” — because honesty costs us sales here, and we still print it.
what a dial is
Every case is scored on four dials. An amber dial is a warning we refuse to hide.
Green means the evidence is strong. Amber means the sources show real risk — weak willingness to pay, a crowded market, or thin proof. We keep it on the page so you find out before you spend a year, not after.

“I spent a year building something nobody needed.”
Not a bad year of work — a bad year of guessing. One amber dial, printed honestly, would have saved it. So we print them, even when it costs us a sale.
Every case that carries the seal, I opened every link myself that morning, with coffee.

“Is it worth it?” — every case file ends with a verdict. This page ends with yours.
the only verdict on this page that's about you
A year of building the wrong thing is the most expensive thing you'll ever buy.
