Claim
"Different" is not enough — many products are different and lose. "Better" is not enough — many products are better in dimensions buyers don't value. The third check is whether the difference matters viscerally to the end user. Cash App's "send a dollar I can use now" is the canonical example: instantly testable, single-sentence, and felt in the body.
Mechanism
Differentiation theory often stops at "show how you're different" and produces a feature comparison. The three-check filter forces you to ground the difference in the user's lived experience. A property is only a moat if it is (a) actually different from competitors, (b) actually better on a measurable axis, and (c) connects to a need the user feels viscerally. Missing any of the three produces a campaign that wins decks but loses buyers.
Conditions
Holds when:
- You can articulate the visceral test in one sentence a non-customer can act on.
- The product genuinely delivers on that test under real conditions.
Fails when:
- The "matters" claim is theoretical (cost savings, efficiency) without a felt moment for the user.
- The "better" axis is the wrong one for the buyer (faster when they care about cheaper, etc.).
Evidence
"Being different is not enough. Being better is not enough. It has to be better in a way that matters to the end user. When someone says 'why bet on Venmo?' I'd say 'try and send me a dollar I can use now.'"

Cash App's "instant" became a durable design principle (instant card issuance, instant stock sell-off, instant Bitcoin cash-out). The compound effect of design depth, fraud prevention, instant settlement, firewall from Square, and consumer-first prioritization is what beat Venmo, not any single feature.
Signals
- Customers describe the product to other customers in a single visceral sentence.
- The "different" property survives feature comparisons because it isn't the feature, it's the moment.
- New features extend the same visceral principle (Cash App made everything instant) instead of accreting around it.
Counter-evidence
April Dunford's positioning work cautions that differentiation must be relative to identified competitive alternatives — "matters viscerally" is necessary but not sufficient. Without the alternatives map, founders fall in love with their visceral story and miss that competitors deliver the same moment differently. Pair Ayo's three-check with explicit alternatives analysis.
