The Opportunity

Problem

Enterprise fintech teams struggle to integrate modern APIs into legacy banking systems, causing significant delays in product rollouts.

Solution

BankBridge automatically generates secure API adapters that map modern REST/GraphQL calls to proprietary legacy banking formats like OFX or ISO 8583. Teams upload their API specs and legacy docs, and it deploys a managed proxy endpoint in minutes, slashing integration time from weeks to hours. Real-time monitoring ensures 99.9% uptime during rollouts.
