7 Signs Your Startup Idea Is Way Too Broad (And How to Narrow It)

By ·

Broad ideas feel ambitious. They're actually just unspecific. The first job of a founder is narrowing — and you can usually tell within 30 seconds of someone describing their idea whether they've done it.

The 7 signs

  1. Your audience is a category, not a person. "Small businesses." "Marketers." "Creators."
  2. You can't name 3 real users. See Niche Down or Die.
  3. Your headline mentions "all-in-one" or "for everyone."
  4. You list 8+ features as the value prop. Real ideas have one job.
  5. Your competitors include category leaders. "Like Notion but better" = you lose.
  6. You can't pick a price within $20. Pricing certainty comes from audience clarity.
  7. The pitch changes every time you say it. Drift = no positioning.

The narrowing exercise

Take your current idea and apply 4 narrowing axes:

  • By industry: "freelancers" → "freelance video editors"
  • By stage: "freelance video editors" → "freelance video editors making $5–20K/mo"
  • By workflow: "...who do client review cycles in Frame.io and waste 4+ hrs/week"
  • By geography or platform: only if it changes the buying behavior

End with a sentence that almost feels embarrassingly small. That's the right answer.

Why narrow ideas grow faster

  • The headline writes itself.
  • You can find 1,000 users in one place.
  • Word of mouth is much faster within tight communities.
  • You become the obvious default in that niche, then expand.

The expansion path

Most founders fear narrowing because they think they're capping the upside. The opposite is true — you start narrow, win, then expand to adjacent niches with the same workflow shape. See The 8 Dimensions for how Target Audience scoring works.
