Trying to integrate with SFDC was a mistake. The product never fit inside of the company. Of course their investment made Heroku successful over the first few years (and eventually highly profitable as I understand) but they should've just spun it off and let it succeed without trying to figure out how to "enterprise" it.

What we knew how to do at Heroku was build a great platform for developers to launch apps. We never claimed to know how to make that model work for enterprise. In fact we were awful at trying.
