Sorry, but this seems very odd to me that a developer would be almost 50% off in estimating their own team size, then post a second comment correcting it only halfway, and finally getting the correct answer by looking at your 'About Us' page?

What kind of working environment do you have that in a team of less than 25, a member of that team can be that far off-base?

Lots of communication via Skype chats in which I don't pay attention to the count of people in the room, and developers split into a bunch of small product teams so I don't have personal dealings with most of them on a daily basis.

Also I'm bad at estimating these things apparently. :P
