The ten ways ideas die.

A guide to the most common reasons startup ideas die. Real anonymized examples. Counter-examples for the rare ones that survive.

Free incumbents saturated

K6 · §3.4.1 · Zero-cost competitors

A market where free tools, free tiers, templates, spreadsheets, or subsidized incumbents already solve the job well enough. The customer is not actively shopping because the current workaround is acceptable and cheap. A paid newcomer must beat both price and habit. That is usually impossible unless it serves a sharply different customer or a clearly different workflow.

Signs your idea has this

  • 01Several free tools already perform the core workflow.
  • 02Customers describe their current workaround as acceptable.
  • 03The main difference is cleaner, simpler, or prettier.
  • 04Switching away from the free incumbent takes little time.
  • 05The buyer expresses low willingness to pay in discovery.
  • 06The free tool is subsidized by a larger business model.
  • 07No forced event makes the customer replace the current setup.

Rare survivors

Superhuman

Survived by selling a premium workflow to a narrow group of heavy email users above the free email baseline.

Linear

Survived by targeting engineering teams with a distinct workflow rather than being a paid version of a free board.

Why this pattern exists fundamentally

Free incumbents set the reference price at zero and make good-enough feel normal. A new paid product must serve a customer the free player cannot serve, create a premium tier with real budget, or own a workflow the free tool cannot absorb.
