$520 million Married with two daughters Interests: real estate development, investments

Valentyn Isak is co-owner of Stolitsa, a real estate developer that suffered heavy losses last year.

The economic downturn, however, did not prevent him from completing his Dream Town shopping mall at the end of 2009.

Focus magazine reported in early 2010 that Isak had invested more than $12 million in the Kyivmiskbud construction company to complete his company’s other unfinished construction projects.

Isak hails from Moldova, where in 1973 he graduated from the Chisinau Polytechnic Institute with a degree in architecture.

He worked as an architect in Moldova before taking a job at Kyiv’s bureau of architecture, Kyivmiskproyekt, in 1984.

Following the collapse of the Soviet Union, Isak founded his own private bureau, Visyak.
