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.
