How do I know if a trend is big enough to build a company on, or just a small niche?

A starting point

Small niches can be great businesses, so the real question is what kind of company you want, not whether the trend is big. Estimate the trend bottom-up: how many people have this problem, how much would they pay, and how fast is that group growing. As a starting point, a niche that's small today but growing fast and underserved usually beats a huge market that's already saturated.

Why we picked it Kevin Hale is a YC partner and cofounder of Wufoo, so this is both the investor lens (what makes a bet worth backing) and the operator lens (someone who built and sold a company). His core move is treating an idea as a hypothesis about why the company will grow fast, which is exactly the question to ask before you sign up for years on it. Use it as a starting point to pressure test your own idea, not as a verdict.

How to Evaluate Startup Ideas

On Y Combinator Startup School by Kevin Hale ~50 min

  • An idea is a hypothesis for why the company will grow quickly, made of a problem, a solution, and an insight, so be honest about whether the growth story holds.
  • You need an unfair advantage, a concrete reason you will win and reach people faster than everyone else, before the years of commitment make sense.
  • Evaluate your own idea the way an investor would, since that is the same lens that tells you whether it is big enough to be worth your life.

Bottom-Up Market Sizing: What It Is and How to Do It

From Visible.vc by Angelina Graumann ~10 min read

  • Bottom-up sizing (count real customers, multiply by realistic revenue per customer) is more defensible because every assumption is one an investor can poke at and you can answer.
  • A top-down number pulled from an industry report signals you Googled a big figure rather than understanding who buys, how many exist, and what they pay.
  • The strongest move is to lead with your bottoms-up number and use top-down as triangulation: if the two diverge a lot, revisit your assumptions before the meeting.
