Jag Duggal is chief product officer at Nubank, a decacorn neobank founded in Brazil. It’s valued at over $30 billion, is bigger than Coinbase, Robinhood, Affirm, and SoFi combined, has 100 million customers (more than Bank of America!) while only operating in three countries in Latin America, and 80% to 90% of its growth comes through word of mouth. Prior to Nubank, Jag was a director of product management at Facebook, a senior vice president at Quantcast, and a product leader at Google. In our conversation, we discuss:

• How Nubank builds a fanatical user base

• Tactics for driving word-of-mouth growth

• Measuring customer love through the Sean Ellis score

• The importance of strategic clarity

• The role of category design in creating successful products

• Why companies should strive to be “fundamentally different,” not “incrementally better”

• Nubank’s vision for an AI-powered banking future
