Value or hype?
20 MINGoal: decide whether your idea creates measurable value, or just looks impressive. You leave this part with a € number and a position on the map.
Can't fill it in? That's normal: it means you need facts from a real customer, not better guessing. The Mom Test is a short book by Rob Fitzpatrick about getting honest answers. Its core rule: ask about facts from their past, never opinions about the future. “Would you pay for this?” invites a polite lie. “What did the last audit cost you?” gets a fact. Write 3 questions of that kind below, ones you could actually ask someone this week.
What is this for?
Before you spend an hour (or a year) on an idea, place it on a simple map: value it creates vs. total effort it takes. The quadrant tells you what to do with it. You don't guess the scores, you calculate them from six questions below.
Why score it twice?
First score your idea as you originally imagined it (the generic version), now. After Part B you come back and score the niched version. Watching your dot move between quadrants is the whole lesson: the same idea, the same tech... only "who it's for" changed.
1 · The generic version (score it now)
Value: how much is solving this worth?
Effort: what does it really take?
2 · The niched version (come back after Part B)
Value: how much is solving this worth?
Effort: what does it really take?
Dot moved? Continue to Part C →Worked example: A11yReview, Part A
A1, the tech-free sentence: “Web teams get every release automatically checked against accessibility law, with fixes proposed in their own code, before an auditor sees the problem.” (The first version was “an AI code review assistant”. Notice how that sentence collapses without the word AI.)
A2, who hurts: the pain: front-end leads and web managers in public-sector teams. Who pays: the municipality IT budget, or the digital agency delivering the site. Today instead: manual checks plus a yearly external audit.
A3, the value equation: ~3 h/week (12 h/month) × €80/h × 52 + €10,000/year in audit findings and rework ≈ €21,500/year per organization. Price: €400/month ≈ 22% of the value created.
A4, matrix, calculated: generic “AI code reviewer”: pain 3, frequency 6, budget 1 → value 3.3. Build 2, sell 9 (everyone competes, no channel), support 6 → effort 5.7. Hype trap. A11yReview: pain 8 (a law with a deadline), frequency 8 (every release), budget 8 (audit money is already being spent) → value 8.0. Build 4, sell 3 (700 customers you can name), support 4 → effort 3.7. Quick win.
A5, kill questions: Most likely cause of failure: audit firms bundle “good enough” tooling, or public procurement is too slow for a startup. Must be true: a municipality can buy a €400/month tool without a tender process, and one reference customer agrees to be named. Better off after 1 month: the web lead ships releases with zero critical WCAG findings and saves ~12 hours.
