D mitry Alexeyev is a Russian self-made billionaire and a co-founder of DNS, one of Russia's largest retailers of consumer electronics and home appliances. He started the business in the late 1990s in the far eastern city of Vladivostok with his partner, Yuri Karptsov. They began by assembling and selling personal computers before pivoting into retail.

They built DNS into a nationwide chain with thousands of stores, becoming a dominant player in the Russian electronics market. The company is known for its wide selection of goods and its competitive pricing. Unlike many Russian billionaires who made their fortunes in natural resources or banking, Alexeyev's success comes from the consumer retail sector. The company remains privately held by the founders and other key managers, and Alexeyev is known for his hands-on involvement in the business.
