Column is a different type of bank built for developers and companies that create financial products through software. It provides banking infrastructure that enables businesses to embed payments, accounts, and lending directly into their applications, rather than relying on traditional banking systems and fragmented intermediaries.

The company was founded by William Hockey and Annie Hockey. William previously co-founded Plaid, a financial infrastructure company that became a core part of modern fintech stacks, while Annie brings experience from consulting and finance roles at firms including Bain and Goldman Sachs.

Column operates as a federally regulated bank and runs its own core systems, ledger, and direct connections to major financial networks. This structure allows it to support USD movement and financial operations without relying on external middleware layers. Its infrastructure is designed for direct connectivity to payment rails, including ACH, wire networks, real-time payments, and card networks. The platform supports a wide set of banking and credit functions, including bank accounts, ACH transfers, wire transfers, real-time payments, book transfers, checks, card programs, loan origination, loan purchase, and debt financing. Each function is delivered through APIs, allowing companies to design and operate financial products within their own systems.

Column is built on the idea that financial infrastructure should behave like software. Every transaction, account, and credit operation is recorded in a unified ledger that updates in real time. This allows companies to manage financial activity within a single system instead of coordinating across multiple providers.

Column is Built for Software-Driven Finance

Column is structured around the needs of developers building financial applications. Instead of offering isolated banking products, it provides a unified system where payments, accounts, and lending functions are connected through programmable interfaces.

This design allows companies to build financial workflows directly into their products. Money movement, account creation, and lending operations can be executed through code, giving builders direct control over how financial systems behave inside their applications.

The system is designed to reduce reliance on manual banking processes and external coordination. Instead, financial operations are executed through APIs that connect directly to Column’s banking infrastructure.

Payments and Core Banking Infrastructure

Column supports multiple payment rails that serve different financial needs. ACH transfers are used for standard bank movement, while wire transfers support higher-value transactions that require faster settlement. Real-time payments allow for immediate fund movement, and book transfers enable internal ledger-based transactions between accounts. Check processing is also supported for workflows that still rely on traditional banking instruments.

Bank accounts are created and managed through APIs, allowing companies to design account structures that fit their specific use cases. These accounts are tied to a unified ledger that tracks balances and transactions in real time, ensuring consistency across all financial activity.

Card programs are part of the platform as well, enabling companies to issue debit, credit, or prepaid cards while controlling transaction rules and spending behavior through software logic.

Lending, Credit, and Capital Infrastructure

Lending is integrated directly into Column’s banking system rather than treated as a separate product. The platform supports loan origination, loan purchase, and debt financing within the same infrastructure used for payments and accounts.

Loan origination allows companies to create and issue credit products through API-based workflows. Loan purchase enables the transfer or acquisition of loan assets, supporting secondary credit activity and portfolio management. Debt financing adds a layer of capital movement tied to lending operations, allowing companies to structure credit products alongside payment and account systems.

All lending activity is recorded within Column’s unified ledger, which tracks principal, interest, repayments, and adjustments in real time. This reduces operational complexity and keeps credit activity aligned with the rest of the financial system.

Unified Banking Infrastructure for Developers

Column is built for developers rather than traditional banking operations. Every banking function is exposed through APIs, allowing financial systems to be embedded directly into application code.

Entities such as users, businesses, accounts, and transactions are managed within a single system. This unified structure allows financial and operational data to exist together, reducing fragmentation and simplifying system design.

The platform connects directly to major financial networks, including Federal Reserve systems and other clearing infrastructure. This reduces reliance on intermediaries and gives companies more direct control over how money moves through the financial system.

The result is a banking system that operates as software infrastructure, where financial functions behave as programmable components rather than fixed institutional services.

Infrastructure for Scalable Financial Products

Column processes large volumes of financial activity for companies building payment systems, lending platforms, and embedded financial products. It supports continuous transaction flows across multiple rails, including ACH, wire transfers, real-time payments, book transfers, and checks.

The infrastructure is designed so companies can expand financial products without rebuilding their systems. New payment methods, lending structures, or account configurations can be added through existing APIs, allowing products to evolve within the same underlying framework.

This creates a stable foundation for financial operations that can scale with usage while maintaining consistent behavior across different types of transactions and financial products.
