Fimple Tech Stack

Cloud-native core banking platform with composable transaction services

IT Services and IT Consulting London, United Kingdom 51–200 employees Founded 2022 Public Company

Fimple builds a SaaS core banking system for regional and mid-market financial institutions, shipping modular transaction and loan capabilities on Kubernetes + PostgreSQL + Kafka. The stack reveals a serious distributed-systems approach (OpenShift, Rancher, Prometheus, Grafana, Elasticsearch, Redis) paired with SWIFT/SEPA compliance work — typical of fintech infrastructure at production scale. Hiring has decelerated to 2 roles in the last 30 days across a 51–200-person org, but active projects signal simultaneous pushes on product (loan module, scalable API development) and commercial motion (regional go-to-market, BDR organization), suggesting they're stabilizing engineering while building out sales.

About Fimple

Fimple is a London-based core banking platform company founded in 2022, positioning itself as an alternative to legacy, monolithic banking systems. The product is a cloud-native SaaS application structured around composable financial services — customers use a Transaction Composer to build and deploy banking products without managing underlying infrastructure. The platform runs on public cloud (AWS, Azure) with Kubernetes orchestration, integrates with banking standards (SWIFT, SEPA), and handles multi-entity financial reporting. They sell to regional banks and financial institutions across the UK, UAE, Egypt, and US, with a mid-market sales motion emerging.
