In this episode

Rabea Bader, co-founder and CTO of Quidkey, explains how cross-border card payments pile up fees, delays and failed transactions, and how Quidkey turns them into local pay-by-bank payments by opening accounts for merchants in each market and predicting each shopper's bank at checkout. He describes validating the idea with hundreds of interviews, adapting to US shoppers who love card points, raising from strategic investors, and why agentic payments for businesses are the next frontier.
