It's important to understand that Byron Sebastian wasn't a founder of Heroku. He was an executive who they brought in later to run the company (because the founders were busy writing code and making the platform awesome). Unlike with other companies, the emphasis was never on the CEO, but on the technically brilliant founders (Lindenbaum, Wiggins, and Henry). It sounds like he accomplished his goal by building the company and selling it, and now it's time for him to move on. The developers are still busy building an awesome service. Echoing what other people have said, there has been no exodus. Throughout its history, Heroku has focused on building an awesome place to work, and they have continued to do this, even at Salesforce. I worked out of the Heroku office for a few weeks (pre-acquisition), and it seemed like a great place to work. Everyone was super-friendly, and seemed to be working on things they truly loved doing (plus, they had a beautiful office that was extremely well-run). I would predict that there are no major staff changes in the foreseeable future.
