Episode Summary

Jag Duggal explains how Nubank became bigger than Coinbase, Robinhood, Affirm, SoFi, and Lemonade combined by building products customers love so fanatically that 80-90% of growth comes from word of mouth. He reveals their rigorous use of Sean Ellis scores (culturally adjusted to 50% for Brazilian optimism) as a gate before scaling any new product, the mock press release technique to force customer clarity before engineering starts, and the mantra that 'good enough isn't good enough — is it great enough?'

Leadership Principles

→ We want our customers to love us fanatically — not incrementally better but fundamentally different, that's the North Star for every product decision
→ We rarely scale a product until we know the Sean Ellis score has hit a threshold we find really compelling — for Brazilians we raised the bar to 50% because they're culturally more positive
→ Good enough isn't good enough — is it great enough? That's the bar, particularly for your tentpole products
