Securely proxy multiple banking APIs without writing backend code.
Solo fintech founders cannot securely integrate multiple banking APIs for payments without a backend development team.
BankMux acts as a secure, serverless proxy that handles authentication, rate limiting, and aggregation for popular banking APIs like Plaid, Stripe, and ACH providers. Solo founders simply configure endpoints via a dashboard and embed a single script into their frontend apps. It ensures PCI compliance and data isolation without needing servers or DevOps.
