BrainTree has been bootstrapped since it's beginning until October, 2012 when they raised $35 million. And the guys at 37 Signals sure love BrainTree since, that is what they use to process payments for 37 Signals. Also, BrainTree was featured in their famous 'Bootstrapped, Profitable and Proud' series http://37signals.com/svn/posts/2800-bootstrapped-profitable-...
