Explores a broad industry or interest area and surfaces specific underserved sub-niches with real signals of unmet demand, instead of generic broad-market ideas.

Best for

Aspiring founders who have a broad area of interest or expertise but need help narrowing down to a specific, defensible niche instead of competing in an oversaturated general market.

Prompt
You are a market researcher who specializes in finding underserved niches within broad industries, the kind big players ignore because they're too small for them but perfect for a solo founder or small team.

Broad industry/interest area: {{broad_industry_or_interest}}
My relevant skills/background (so niches can be realistically matched): {{relevant_skills_background}}
Business model preference (e.g., service, SaaS, content, physical product, marketplace): {{business_model_preference}}

Do the following:
1. Identify 5 specific underserved sub-niches within the broad area, each one narrow enough to be genuinely specific (not 'fitness for busy people' but something like 'strength training programs for postpartum runners returning to marathon training').
2. For each niche, explain the signal suggesting it's underserved (e.g., existing solutions are too generic, a specific community complains about this gap, a demographic shift creating new unmet needs).
3. Note how well each niche matches the stated skills/background and business model preference, flagging the strongest fit.
4. For the top 2 niches, suggest one simple way to validate real demand before building anything (e.g., a specific online community to survey, a low-cost test offer to run).

How to use

  1. Describe your broad area of interest and your relevant skills or background honestly.
  2. State your preferred business model so niches suggested are realistic to pursue given how you want to work.
  3. Research the underserved signal claim for your top niches yourself to confirm it holds up.
  4. Run the suggested low-cost validation step before committing significant time to building anything.

Example input

Broad area: Online education/course creation. Skills: 10 years as a corporate trainer, strong at instructional design. Business model preference: Digital product/course.

Example output

5 niches including 'onboarding training courses specifically for remote-first startups under 20 employees' and 'compliance training templates for small healthcare clinics,' each with a signal explanation such as generic LMS platforms being too broad for small clinic-specific compliance needs, a strongest-fit flag on the compliance training niche given the corporate training background, and a validation suggestion to post in small healthcare practice management Facebook groups asking about current compliance training pain points.

Customization tips

  • — If you have any existing audience or community you're part of, mention it so niches can be matched to your built-in distribution advantage.
  • — For location-dependent business models (local services), specify your location or target geography.
  • — Ask for niches ranked specifically by 'fastest to validate' if you want to move quickly rather than by pure market size.

FAQ

What is this prompt for?
It surfaces specific underserved sub-niches within a broad industry, explains the signal suggesting real unmet demand for each, and matches them against your skills and preferred business model.
How should I customize it?
Be honest and specific about your relevant skills and background, since the best niche fit depends on matching real unmet demand with something you're actually positioned to deliver well.
Are there any limitations?
Underserved signals are reasoning-based estimates, not verified market data; always validate a promising niche with real conversations or a small test before investing significant time or money.
How is it different from a basic prompt?
Instead of generic business ideas within a broad category, it forces genuinely narrow, specific niches with an explained underserved signal for each, and matches them against your actual skills rather than suggesting generic ideas anyone could pursue.
