Day 1: Define the one job
Write the problem in one sentence, the user in one sentence, the outcome in one sentence. If you can't, you're not ready to test — you're still figuring out the idea.
Days 2–3: Build the landing page
Headline, three benefits, one screenshot or sketch, one CTA: 'Get early access' with a pre-order button. Use Lovable, Carrd or Framer — whatever you can ship in an afternoon.
Days 4–5: Drive 200 targeted visitors
$100 of ads to a sharply defined audience. Or 100 cold DMs to people who clearly have the problem. Quality of traffic matters more than volume at this scale.
Days 6–7: Read the numbers honestly
Above 5% conversion to email + 3 pre-orders = build it. 1–5% + a handful of replies = iterate the headline. Below 1% = kill it and move to the next idea. Be ruthless — the next idea is the one that works.
Why this beats market research
Surveys tell you what people think they want. A landing page tells you what they'll act on. Action beats opinion every time.
