PRESS RELEASE
Krom Bank renews multi-year partnership with Mambu to
accelerate digital banking innovation in Indonesia
Jakarta, Indonesia Amsterdam, Netherlands 15 October 2025
PT Krom Bank Indonesia Tbk (“Krom”), a leading digital bank and subsidiary of Kredivo Group, has renewed its partnership with global SaaS cloud banking platform Mambu for five years after a successful collaboration on the launch of the Krom digital banking app in 2024. The extended partnership underscores Krom’s continued confidence in Mambu’s composable core banking platform as it continues its mission to grow profitably and reach over 20 million accounts by 2030.
Krom aims to serve the 75% of the Indonesian population that remains unbanked or underbanked. The bank selected Mambu as its core banking partner in March 2022 and in under 12 months, it went live with personal and business daily banking products, including current accounts, savings and term deposits.
Since then, Krom has emerged as one of Indonesia’s fastest-growing digital banks, leveraging Mambu’s core banking platform and cutting-edge cloud technologies from Amazon Web Services (AWS) to bring high-yield, fully digital financial services to young and underbanked Indonesians.
The renewal strengthens Mambu’s presence in APAC where it helps established banks modernise their core infrastructure and innovate, and helps digital natives to launch and scale quickly.
This marks a deepening strategic partnership with a digital-first innovator at the forefront of financial inclusion in Southeast Asia. Mambu will enable the continued rollout of innovative financial products over the next five years at speed and scale, including additional deposits and loan offerings tailored to Indonesia’s digital-native consumers. The bank also plans to integrate generative AI-driven services, enhance workforce cloud capabilities, and further accelerate product development - all supported by Mambu’s scalable core and AWS infrastructure.
