After losing money in a skincare company, a pizzeria and a cat furniture company, Wilkinson reduced business quality to a small number of defensibility tests. On the internet, he says two things generally work: a network effect, where each new user makes the product harder to leave — Dribbble for designers, Letterboxd for film buffs, where $100M of funding still wouldn't move users whose friends and reviews live there — and a brand moat, where the name becomes the category, like Coke versus Acme Cola or Kleenex versus facial tissue. He adds a third for creators: the personal monopoly created by parasocial relationships. An audience that has listened to you for years feels it knows you, and that relationship cannot be replicated by a competitor because nobody else is you. Screen any business idea against these before building.

How to run it
- 1
Learn what a good business looks like before betting big
Wilkinson's discernment came from starting many bad businesses and losing money on each. Study the model and the mistakes first rather than assuming early success makes you a genius.
Watch out Don't walk into the gym and deadlift 300 pounds on day one — you'll hurt your back.

Test for a network effect
Ask whether each additional user makes the product more valuable to everyone else. If a well-funded competitor with a better-designed product still couldn't pull users away because their friends and history are on yours, the moat is real.
Pro tip User-generated history — reviews, portfolios, archives — deepens the lock-in beyond the social graph.

Test for a brand moat
Ask whether people will pay a premium for the name even when a functionally identical or better-tasting alternative exists. The strongest version is category-defining, where the brand becomes the word for the product.
Watch out Blind preference tests can favour the competitor and the brand still wins — treat brand as a separate asset from product quality.

Test for a personal monopoly
For creators, the parasocial relationship — one-way familiarity built over years of content — is uncopyable. Someone who has read your books and listened to hundreds of hours of you feels they know you, and no competitor can manufacture that.
Pro tip Wilkinson describes meeting Tim Ferriss and feeling he'd known him for decades — that is the asset, measured across hundreds of thousands of people.
Watch out The trade-off is that you must keep appearing on camera to operate the business.

Reject markets with no moat available
If none of the three apply, expect infinite competition and disloyal customers. Wilkinson's example is productivity software, where a new venture-funded competitor appears constantly and users are never loyal.
In the wild
Wilkinson owns Dribbble, the largest social network for designers, and Letterboxd, the largest social network for film buffs. He argues that if you took $100 million and tried to recreate Letterboxd, you'd struggle to get going — a challenger might be better designed, faster, and have more features, and users would still say all their friends and all their reviews are on Letterboxd and refuse to move. The accumulated graph and history are the defence, not the feature set.
→ Two category-leading networks that are structurally very hard to attack with capital alone.
Wilkinson built Flow, a GTD tool for teams, and launched to $40,000 a month of MRR and TechCrunch coverage. Six months later a Facebook co-founder launched Asana with hundreds of millions in venture capital. Wilkinson dismissed the product as ugly and developer-built, expecting to win on merit. Asana outspent him on marketing, then out-shipped him on features and eventually design. He compared it to Fiji invading the United States and lost about $10 million of his own bootstrapped money.
→ A ~$10M loss in a category with no network effect, no brand moat and no customer loyalty.
Common mistakes
Assuming early success means you're a business genius
Wilkinson's agency succeeded on skill fit, zero startup cost and luck. He read that as general competence and lost money across a skincare company, a pizzeria and a cat furniture company before learning to evaluate business models.
Betting on winning on merit
In a market with no moat, a better product loses to a better-funded one. Flow was better designed than early Asana and still got outflanked on marketing, then features.
Ignoring customer loyalty in the category
Productivity tool users, by Wilkinson's own admission, constantly try the new hotness. A category where nobody is loyal cannot support a durable business unless you get very lucky.
