The Bank Built for the Frontier
from Wharton FinTech Podcast Hosted by Wharton Fintech Podcast
In this episode of the Wharton FinTech Podcast, Bobby Ma sits down with Alex Du, COO of Column. Alex dropped out of Stanford GSB to build Column with Plaid co-founder William Hockey. Column is the only nationally chartered bank built for the frontier, powering some of the fastest-growing technology companies, including Ramp, Mercury, and Bilt. It processes more than $4.5 trillion in annual transaction volume, is the #1 issuer of real-time payments in the US, and has the highest uptime of any bank, all with a team of about 150 people. We discuss: his path from finance to COO; the "championship DNA" culture behind one of the leanest, most agile teams in banking; how owning its entire tech stack sets Column apart; where AI is genuinely changing financial services and where it's just noise; and how Column supports companies pushing into stablecoins, cards, agentic payments, and cross-border payments.
