Case Study: TNEX builds Vietnam’s leading digital bank with Mambu

TNEX - Customer Case Study

TNEX, a digital bank established as a spinoff of Maritime Bank (MSB), sought to meet the needs of Vietnam's young, mobile-first population. The challenge was to build a digital-only banking experience unencumbered by the outdated systems of traditional banks, requiring an infinitely scalable platform that would allow them to focus on solving customer problems rather than managing infrastructure. They chose Mambu's cloud-native core banking platform to serve as their foundation.

The solution was a cloud-native, composable approach using Mambu’s API-first platform, which was integrated with specialized tools for identity verification and payments. This enabled TNEX to launch its consumer platform in just 10 months. The results were significant, with Mambu helping TNEX grow to over 2.4 million customers by Q2 2025 and be named “Best Digital Bank in Vietnam” for three consecutive years.
