"I can't believe nobody's doing this yet" - 5 cash cow business ideas

From My First Million · Published Jul 4, 2025 · Watch on YouTube

TL;DR

Five business ideas are presented: (1) a 360-degree self-awareness test where others rate you, (2) embryo selection as a service for wealthy parents, (3) scanning and selling prints of people’s eyes as art, (4) mold cleanup services sold via fear-based Facebook ads, and (5) replacing St. George’s Day with “Dunkirk Day” to rebrand UK national pride.

Key insights

  • Advertising should be designed first: compress the idea into a two-second, emotion-filled hook that a scrolling user immediately understands and acts on.
  • Personality tests go viral because people are their own favorite subject; adding a “what do others think of me” twist leverages the social graph (like early Bebo’s “best friend test”).
  • The planning fallacy (tasks take three times as long and cost twice as much) persists even when you know about it; being aware does not prevent it.
