ELAD GIL'S FRAMEWORK FOR SPOTTING BILLION-DOLLAR MARKETS BEFORE THEY LOOK BIG

Summary from the TLDR Founders newsletter

Markets beat teams beat ideas - great teams can't escape bad markets, but great markets give you multiple shots on goal. Wedding invitations seemed too niche, payroll too boring, file storage too late, then became Minted, Gusto, and Dropbox. Four principles for finding overlooked opportunities: use first principles to ask what's changed in cost or infrastructure, scratch your own itch with real pain, not vague ideas, build product-first because "would you use this" is weak but "would you pay now" is real, and look where smart people tinker for fun before mainstream notices.
