How much of the market do I realistically need to capture for this to be a real business?

A starting point

Flip the question: instead of guessing a market share percentage, work backward from the revenue you need to be a healthy business and divide by a realistic price to get the number of customers, then ask if that many buyers plausibly exist and are reachable. Round numbers like getting one percent of a billion-dollar market are meaningless because nobody wins customers by percentage, they win them one segment at a time. As a starting point, if the customer count you need feels impossible to reach with the channels you actually have, the market being large won't save you.

Why we picked it This is the cleanest takedown of the most common beginner mistake: pitching a market as "we only need to capture 1 percent." It walks through why that number is not a plan (power-law markets reward the top few, and 1 percent of a big market is elite territory, not a modest slice), and what to reason about instead: who you can actually reach, at what cost, and whether you can lead a narrow segment. Read it as a starting point for sizing your real obtainable market, not the headline TAM.

Why "All we need is 1% of this very large market" is a red flag

From N47 by Lak Ananth ~8 min read

  • "We only need 1 percent" quietly assumes away the hardest parts: customer acquisition cost, win rate, and whether you can ever lead a segment.
  • Markets concentrate. Capturing even 1 percent usually means ranking among the top handful of players, so treat it as an ambitious claim you have to defend.
  • Start from a specific problem solved well for a defined customer set, then build the number up from real customers and pricing.
