I went with my bosses to visit one of our competitors a few weeks ago; they invited us for a tour. The CEO of the competitor believed that employee count was a direct indicator of the strength of a business. He bragged about having a staff 3x my company's, but the fact is that based on sales data, we're far more efficient, doing a percentage of their sales larger than the ratio of staff sizes.
Reddit was 4 until recently. They did say they felt like they couldn't really go forward anywhere with that kind of staff although. I don't know if the new 2 hires are enough.
