Get creditsBuy with your risk reversed
- See the price first. Every run shows its exact credit cost before you spend it — no surprise charges.
- A failed run is free. If a run errors out on our side, its credit is refunded automatically.
- Credits never expire. Buy what you need and use it whenever. No subscription, no sales calls.
- 14-day pack refund. Unused credit packs are refundable within 14 days.
- It's willing to say no. A weak market hands back nothing, with the reasons — you keep the rationale, not a build you'd regret.
What one credit gets you.
One credit buys one answer: Build it, Test it first, or Drop it — with the reasons, the biggest unknown, and one thing to do next. A Discovery run spends a few credits and gives you something a scoring tool can't: ideas we went and found, each one backed by a problem with a link you can click. If the market is weak, we hand back nothing and tell you why. You still learn something worth more than the credit.
How credits work: most analyses (Single Idea Check, Kill My Idea, Founder Fit, Pricing Power, …) cost 1 credit; Compare is 1 credit per 3 ideas (rounded up); a Discovery run costs 2 credits for the first market, +1 for each extra market — every market is searched separately, so the price follows the work. You see the exact cost before every run. New accounts start with 2 free credits; Discovery always needs a paid credit. Unused packs are refundable within 14 days.
Before you buy anything.
2 free credits land in every new account. They cover a founder read and one idea check — real runs, full output, no card. They do not cover a Discovery run: a run searches and reads for tens of minutes, so it always needs a paid credit. If you want to see one first, read a real one — no account needed.
What one run actually does
One Discovery run plans your market into sub-markets, runs live searches across search engines, listing sites and public APIs, reads the pages it is allowed to read, and carries up to 150 candidates through a fixed set of deal-breaker checks before handing back at most 5. The 0–100 score is computed in code from a fixed weighted checklist; the AI rates each area and never sets the total. The run we publish made 60 searches, read 24 pages, sourced 69 candidates and killed 36 of them with a named reason.

- Verifiable evidence, not summaries. Discovery pains carry clickable source links — a fetched page or a search snippet — or are honestly marked not verified. On the run we publish, 32 of 56 carry a link, and the page says which ones don't.
- A gate that compounds. Every sweep writes to one shared record of problems, across all users and markets — so each run is smarter than the last, and recurring sweeps get harder to fool over time.
- A decision that's willing to say no. A weak market honestly hands back nothing, with the reasons — that's the gate working, not a bug. And if a run errors out, it auto-refunds its credit.
Why not just ask a chatbot?
A chatbot is built to be helpful, so it tends to agree with you. This is built to say no — the default answer is drop it, and a weak market comes back with nothing. The 0–100 score is computed in code from a fixed checklist; the model rates each area but never sets the total, so it cannot talk itself into a passing number. And every problem we cite either links to the page we found it on or is labelled as our own estimate.
