Tier A · TL;DR
Pick a niche where the fish are; do not deadlift 300 pounds on day one

Claim

Most failed startups copy a hot market that has already chewed up better-capitalized competitors. The reliable move is to pick boring, undermonetized verticals where customers have real willingness to pay and incumbents are weak, even if the market looks small. Government form-filling software at $30M ARR beats a fifth Asana at zero ARR.

Mechanism

A market with many failed attempts has a structural moat against you, not a whitespace. Distribution, network effects, hiring, and capital expectations are all set by the prior round of competitors. Entering as a smaller, later player means competing against established advantages with none of your own. Boring, neglected niches have the inverse property: little competition, willing buyers, and a chance to build distribution, brand, and capital before any large player notices.

Evidence

"I lost $10M on Flow, competing with venture-backed Asana. Don't deadlift 300 pounds on day one. There's a guy doing $30M a year on government form-filling software."

Wilkinson has founded or been involved with 75 businesses. The "Things" task manager, bootstrapped, fewer than 10 people, 20 years old, succeeds in the same category that ate Flow because Things picked a lifestyle niche the venture-backed players ignored.

Signals

Counter-evidence

Some founders are uniquely capable of competing in saturated markets through a specific structural edge (founder distribution, technical breakthrough, regulatory advantage). Brian Chesky's Airbnb entered "online lodging" against Craigslist + Couchsurfing. Wilkinson's rule is the default; rare exceptions exist when the founder genuinely has an unfair advantage.
