Charles Egly and Geoffroy Guigou founded Younited in 2009. The company won approval as a credit institution in 2011 and opened to the public in December 2011 as Prêt d'Union, the first French platform of its kind. It raised €9 million in 2010 and 2011.
In 2016 it was renamed Younited Credit, opened to institutional lenders and launched in Italy. Spain followed in 2017, Portugal in 2018 and Germany in 2020. It had financed €1 billion by January 2019 and granted €3 billion by early 2022.
In July 2021 it raised $170 million. In December 2022 a €60 million round made it France's 28th unicorn. Revenue was about €125 million in 2021.
Younited listed on Euronext Paris on 20 January 2025 at a valuation of about €622 million, far below its 2022 peak. In May 2025 it agreed to buy the neobank Helios. Egly remains Group CEO.
