Job description

We are a UK fintech creating successful neobanks in emerging markets in partnerships with local traditional banks. The mission is to make banking services accessible, simple and fun to use worldwide and the goal is to launch neobanks in 50+ markets, serving 100m+ customers.

Our success builds upon a best-in-class product, customer experience, emotional engagement, viral marketing and deep credit-decisioning expertise across our product suite covering credit, payments, savings and investments. One of our founders also previously co-founded a highly successful Eastern European neobank with a multi-million customer base.

We launched our first market with Leobank in Azerbaijan in 2021, where we’ve already taken a leading market position.
