Origin Story

Tuum was founded by five Estonian banking technology pioneers in a nation recognized as the world's most advanced digital society, combining business expertise with cutting-edge technology to create an API-first, cloud-agnostic, modular core banking platform without coding needs.[3] Key co-founders include Chief Technology Officer Ove, whose career spans Ernst & Young, Icefire (as Head of Research and Development for Nordic banks), and a 2018 Fintech Futures award for IT in corporate banking; and others driving the vision to break digital innovation barriers in banking.[3] The idea emerged from Estonia's digital transformation, aiming to empower financial institutions with fast, customer-centric services; early traction built through this innovative approach, powering a range of clients from large banks to fintechs.[3] Led by CEO Miljan (with prior roles at Mambu and Backbase), Tuum has evolved into an innovation engine with a supportive, diverse culture focused on continuous learning.[3]
