Their flagship product, Lesslie PAY, is a platform for international payments with automated accounting, fast currency services and free express payments.

Lesslie is a fast‑growing fintech startup with between 11 and 50 employees and backing from investors such as Wellstreet Fintech Fund I. They raised a significant round in February 2024 after 500% growth in 2023.
