coocon

Coocon operates a data-brokerage platform that collects, standardises, and delivers information from financial institutions, government bodies, and other organisations to business customers via application programming interfaces (APIs), the connectors that let software systems talk to each other.

Its clients include banks, fintech and big-tech firms, public agencies, and general enterprises that use the APIs to power services such as personal finance management, automated banking, and payment processing. Listed on KOSDAQ, Korea's tech-focused stock exchange, the company earns revenue through two main lines, data services and payment services, with a recurring monthly-fee structure making up the bulk of income.
