I agree. I have not listed many cool companies. It is a long and IMHO impressive list.
TargetProcess, PandaDoc, FriendlyData, Eightydays.me, Maps.me (was acquired by Mail.Ru Group), SplitMetrics etc. Plus the biggest company is Epam (Market Cap, 7.406B).
However, we do have some great success stories (e.g. AIMatter (was acquired by Google), MSQRD (was acquired by Facebook)).
Most promising startups incorporate in US from day one and raise money there. In addition, there are number of funds in Russia or Ukraine.
In other words, if you have an interesting idea, you will find money or money will find you :)
