About our Company
LemFi ( YC S21 ( is building the neobank for African diaspora in North America & Europe. We provide our users with a multi-currency account that allows them to hold, send, and receive money from Africa in any currency for their business and personal banking needs.
There are over 10 million Africans living in North America & Europe who go through hoops and have to pay exorbitant fees to send money to their loved ones. We are constantly fighting for everyday Africans to be able to move their money freely around the world at no cost and with the best exchange rate they can find out there.
We launched the first version of the app at the beginning of October 2020 with just the ability to send money. Now, we enable our users to send and receive as well as pay bills for services across the ocean for loved ones. We have also grown to a team of more than 40 people working remotely and living in different continents around the world.
