Our competitors are 10 - 1000 times larger than us. Doesn't help us in any way for them to know our size.
And the couple of customers that know our size have indicated it's better to appear large. For example, you wouldn't switch a company from using Microsoft Exchange to something else if that something else was run by a couple of guys. Our company would be in very deep trouble if something happened to me. To balance that, customers get updates and fixes very fast because they work with such a small company.
