I have worked in a couple of early stage growth businesses and to go from $15 to $120M revenues is possible in 8-10 years and ending up with about 65 staff.

To get a 50% revenue growth rate for 10 years would be a bit of a stretch, I would think.

Whenever looking at a business there are always two factors.

1. Revenue multiples and what the accountants believe it is worth
2. No revenue and what the market attributes to blue sky potential

In the short term No. 2 will give the greatest return, just make sure you hop out before the blue sky turns to gray.
