FriendFeed is based in Mountain View, Calif. and has 12 employees.
The most interesting point, for me, is that FriendFeed has only 12 employees! I know I shouldn't be supprised in this new age of small startups that stay small, but the site just oozed polish, features and performance. I expected them to at least break 40 employees. Kudo's to those guys and I hope they got some good cash in the deal.
