The core of banking is broken, and duct-taping legacy systems won’t fix it.
This week on Couchonomics with Arjun, I’m joined by Myles Bertrand, CEO of Tuum, the modular core banking platform built in Estonia and now scaling across Europe and the GCC.
Tuum isn’t selling digital lipstick. They’re rebuilding the real plumbing of modern banking — one composable, cloud-native layer at a time.
💡 In this episode:
- Why full core replacement is a myth — and composability is the real unlock
- How to modernize without breaking everything (or everyone)
- What it takes to scale infra platforms into the GCC
- Where AI fits in — and where it doesn’t
- Why institutional banking might be the biggest opportunity for transformation

If you’re in banking, infra, SaaS, or scaling into MENA, this episode is required listening.
