Russian "Bill Gates"

Still, there are men in Russian villages - a team of 10-15 developers was able to come up with an idea and, most importantly, realize it in such a way that now we have a worldwide promoted, in-demand and commercially successful product ...

A cool storyline on Russia.ru about Nikolai Dobrovolsky - he once got the idea to develop Windows virtualization software on Mac. In the West, especially in the States, Parallels knows everyone who needs Windows on a Mac, but probably units are aware that this product is made by Russian programmers.
It is clear that after 1.5 years, Vmware released a similar solution, and now these two products are actively competing with each other. But Parallels Desktop for Mac is still the market leader in various countries. Depending on the geography of sales, it operates from 55% to 70% of local markets.
