Basically, don't expand... Or, add one employee every 5 1/2 years!
I want to address it though, because it's not entirely wrong. Zildjan stands as a counter-point to the prominent VC model. They did not rapidly expand, and yet, as the article states, they have managed to capture a huge portion of the market.
It's not really an apples-to-apples comparison, but I suspect there are many virtues that we sacrifice in the name of growth and speed.
