QED Investors is founded and led by Capital One co-founders who built one of the world's most data-driven banks, and they explicitly port Capital One's "fanatical focus on unit economics" and hypothesis-driven experimentation into venture capital as an operator-driven fintech specialist. The firm operates with an unusually operator-heavy, fintech-only partnership with 250+ years of combined operating experience and deploys a distinctive company-building model where they form hypotheses about fintech white spaces and either back the best team or literally stand up and fund companies from "PowerPoint stage."
