Plenty, but it's a lot easier for a company to bootstrap and hit $1MM in revenues and be profitable than it is to be the next Apple or Google or younameit.
Trying to be the next google or younameit is playing the lottery, no argument there. Bootstrapping to $10-100MM strikes me about as unlikely as being the next google.
That's not even a contest. $10MM+ bootstrapped companies are far more common than "being the next Google." More stories on the way.
