Senior Data Scientist

This is a UK remote position

Who we are

The current system of credit, based on bureau data, is deeply unfair, penalising people who live in lower income areas, people who are new to the country or customers who have used high risk products in the past (such as payday loans). Koyo was founded in 2018, on the principle that everyone should have access to affordable credit regardless of where they are from, where they live, or types of credit that have used.

Many seeking credit are charged excessive fees and interest rates for borrowing that cause financial problems, rather than solve them. We’re changing all that.

Koyo uses innovative technology to offer fairly priced credit to millions of UK customers. We’re based in London, with global ambitions. Koyo is backed by leading venture capital funds (the same funds that backed the likes of Revolut, Transferwise and others) and some of the most reputable angel investors in the UK. Join us, and help put an end to predatory financial firms and be part of an exciting and rewarding journey.

Our story so far

In 2016, Thomas, the founder of Koyo moved to the UK and found accessing credit to be difficult if not impossible. This is because his credit history did not follow him from his home country. He realised that having an imperfect credit history affects millions of people who are new to the country, but also people who have failed to build a credit history in the UK more generally. In September 2018 we raised our first round of venture funding and have since raised further debt and equity funding from venture capital funds and private investors.
