Column built an issuer processor from scratch

summary

Column is eliminating the complexity of launching card programs by combining the functions of an issuing bank, issuer processor, and capital provider into a single integrated system. By removing the need for multiple third-party partners and middleware, the company allows developers to launch credit, debit, or prepaid programs via a few API calls. This vertical integration reduces time-to-market from months to weeks and minimizes potential points of failure in the payment stack.

key points

1. The platform provides a unified API for the entire lifecycle of a card, from originating credit lines and binding accounts to issuing physical or virtual cards. It supports diverse form factors including plastic, metal, and stablecoin-backed cards across various program types.
2. Developers maintain granular control over transactions through real-time webhooks that allow them to approve, decline, or challenge authorizations based on merchant data and fraud scores. This control extends to mobile wallet provisioning and remote token management.
3. Because the processor is built on Column's own banking infrastructure, card programs integrate natively with other financial tools like ACH, Wire transfers, and global banking services. This allows for advanced features like 3DS, dispute management, and USDC settlement out of the box.
