Heroku's exit was pretty huge for its time. In fact it was the largest YC exit to-date. For context Heroku was created in 2008 just after the housing crash. By the time they exited Facebook was still 2.5 years away from going public and a solid seed round still looked like a few hundred grand if you were a hot company (on top of the ~17k you'd get from YC).
