LemFi Tech Stack

Cross-border fintech app for remittances, savings, and multi-currency accounts

Financial Services London 201–500 employees Founded 2020 Privately Held

LemFi operates a mobile-first financial platform for Global South users, with 2M+ customers across remittance, savings, and multi-currency services. The tech stack (Kafka, PostgreSQL, Redis, Go, Kotlin/Java for mobile) reflects a mature backend built for high-throughput money movement, while active adoption of analytics tools (Segment, AppsFlyer, Branch, Google Tag Manager) signals a data-driven user acquisition push. Engineering dominates hiring (24 of 62 open roles), but the friction is regulatory: pain points cluster around AML compliance, multi-jurisdiction data protection, and fragmentary banking integrations—classic fintech scaling challenges.
