I was employee 40 at a startup that went to 400. I think Dick's advice is right. The hardest part is losing many of the early employees once you hit about 150.

I was employee 40 at a startup that went to 400. I think Dick's advice is right. The hardest part is losing many of the early employees once you hit about 150. But the bigger problem would be trying to keep them. You need different skill sets and different people for different stages. It hurts though. (also agree that the Zappos piece was much more interesting to me - but Vegas?! It's tough to go outside 3 months of the year after 9am)
