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.

• How Nubank builds a fanatical user base
• Tactics for driving wordofmouth 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 AIpowered banking future
