About AutoProff

AutoProff was founded in 2013 by the experienced car dealer Jesper Ratza in Denmark. The aim was to digitalize B2B used car trading, helping car dealers increase sales and improve profits. In August 2022, AutoScout24, the leading specialized pan‑European online car marketplace, acquired a majority stake in AutoProff. The partnership has supported the rapid expansion of AutoProff's solutions across Europe and enables the creation of Europe’s first fully integrated C2B‑B2B‑B2C dealing solution for used cars. At AutoProff, we specialize in providing online B2B used‑car dealing solutions designed to improve the buying and selling experience for professional car dealers and their customers. We are the emerging European leader with more than 150,000 B2B used cars on our online trading platforms annually.
