The number of employees doesn't really matter these days. Lots of the day-to-day boring stuff should be outsourced/contracted anyway, keeping the company lean and mean and focused on what makes it different from others. Helps when the bubble bursts too - you can scale down quickly without having to deal with thousands of layoffs.

Having said that, this one sounds particularly bubbly. I said the same about Amazon and Netflix years ago so you know I'm an expert.
