Tuum is an Estonian cloud-native core banking platform that helps banks, fintechs, and non-financial companies rapidly launch financial products through its modular, API-first architecture. The company has achieved impressive growth with over 250% compound annual growth rate over three years and now serves customers across 10 countries, particularly strong in the UK and Nordics. Founded in 2019 by Estonian banking technology experts who helped digitize major Nordic banks, Tuum raised €25 million in Series B funding in February 2024 led by CommerzVentures. The platform enables banks to modernize their legacy systems incrementally and launch new products in weeks rather than years, with successful migrations completed in as little as 2 months.
