About LemFi

LemFi is a London-founded fintech app serving migrant workers and residents across emerging markets. The platform consolidates international money transfers, multi-currency accounts, savings, and credit access—addressing friction points for users who send remittances, maintain savings across borders, or lack credit history in their current country. The product reaches over 2 million customers globally. Operationally, LemFi is managing a complex compliance and payments infrastructure (Kafka, PostgreSQL, AWS) while scaling into multiple regulatory regimes simultaneously—a driver of their finance and legal hiring emphasis and documented pain around regional compliance and process standardization.
