SoFi

Sophie started with a single problem. Student loans were expensive, and refinancing was complicated. The company offered better rates for borrowers with good credit. That was the entry point. But the founders knew something. If they lowered someone's loan payment, they'd capture trust. That trust was the asset. What else could they sell to a customer they'd helped? Sophie expanded the product line, investing, banking, insurance, crypto. Each product was built on trust from the previous one. A customer came for a better loan rate, got it, then discovered they could invest, bank, and insure through the same app. Cross-sell rates accelerated because customers already had a relationship.
