Here's something you don't see every day in fintech: Sadi Khan, a 40-year-old founder steering the fintech outfit Aven, just announced that both he and his company are putting millions into launching a brand-new federal credit union. It's a bold play that signals something bigger—traditional banking infrastructure getting a serious rethink from the startup world. The move raises an interesting question: as fintech continues to disrupt payments and lending, what happens when entrepreneurs start building the actual institutional backbone? This kind of cross-pollination between crypto-native thinking and legacy finance structures could reshape how retail customers experience banking going forward. Whether it succeeds or stumbles, it's definitely worth watching as the line between fintech innovation and traditional financial institutions keeps blurring.
