RIA. com is a Ukrainian IT company that develops AUTO. RIA, DIM. RIA, AGRO. RIA, and RIA. com — products used by millions of Ukrainians. The company’s mission is to build a trusted internet. With a focus on reliability, RIA. com’s marketplaces create transparent and secure markets for automobiles, real estate, and agriculture. RIA. com is part of the international group RIA. com Marketplaces OÜ, founded by Ukrainians. The company’s flagship products — AUTO. RIA and DIM. RIA — have long been familiar to Ukrainians. However, as an IT company creating and scaling these well-known marketplaces, RIA. com began its active development in early 2014. We consider this moment a new starting point, as both the company and its products have undergone significant transformations since then. Founded in Vinnytsia, RIA. com brings together specialists from across Ukraine. Our colleagues work from Lviv, Kharkiv, Odesa, Kyiv, and even from abroad on a temporary basis. By focusing on talent, we are building a nationwide online office, complemented by our physical office in Vinnytsia.
