Power financial products with Episode Six’s flexible, API-first cards and ledger infrastructure—built for banks, fintechs, and brands to innovate faster.

How do you want to pay? It’s a question you’ve answered on-screen or in-person thousands of times, but your choices have always been limited. Imagine the flexibility to pay however you want - credit, debit, multiple currencies, frequent flyer miles, loyalty points, or digital payments - all on the same card or digital wallet. Sound impossible? Episode Six makes the seemingly impossible happen every day.  

We’re a global provider of API-based payment processing and wallet management infrastructure. We’re 100% cloud-native, hyper-configurable, and a “Top 10 Place to Work in Fintech.” And we’re changing how people think about payments.  

Today, we’re powering payments for one of the world’s largest banks and airlines and numerous innovative fintechs. E6 is headquartered in Austin with offices in Tokyo, Singapore, Brisbane, and London. We provide technology for clients in 24 countries on four continents. Since 2018 when we launched with HSBC, we have grown more than 10x.  

Interested in redefining what’s possible in payments? Join Episode Six today.
