Nubank utilizes the Sean Ellis survey ('How disappointed would you be if this product went away?') as a strict gate. They adjust the standard 40% threshold up to 50% to account for cultural politeness in Latin America, ensuring true 'fanatical love' before growth investment.
Core Principles
- 1.Survey customers asking if they would be 'very disappointed' without the product.
- 2.Set a strict threshold (e.g., 50%)—if unmet, do not scale.
- 3.If the aggregate score is low, analyze sub-segments/cohorts to find the 'bullseye' users who love it.

"We rarely scale a project until we know the Sean Ellis score hit a threshold that we find really compelling."
