Column is a nationally chartered U.S. bank built by Plaid co-founder William Hockey and his wife Annie, who purchased Northern California National Bank in 2021 and rebuilt its core infrastructure from scratch. Unlike sponsor-bank competitors that rely on third-party cores, Column owns the entire stack — charter, ledger, payment rails — and exposes them via developer APIs. Sacra estimates Column generated $153.1M in revenue in 2025, up 219% year-over-year, with reporting suggesting a valuation as high as $6 billion.
