K onstantin Nikolaev is a Russian businessman with significant investments in the transportation and infrastructure sectors. He is a co-founder of Globaltrans, one of Russia's largest private freight rail transportation companies. He also co-founded N-Trans, a major transportation holding company in Russia, which managed interests in ports, railways, and other logistics assets.

Nikolaev and his partners built their fortunes by capitalizing on the opportunities in Russia's vast and essential transportation industry. Globaltrans became a key player in the movement of bulk goods like coal, metals, and oil products across the country's extensive rail network. While he has sold down some of his stakes in these core businesses, he remains a significant investor with a diverse portfolio. He has also ventured into other areas, including investing in technology startups in the United States and co-founding a public policy think tank at a U.S. university.
