I'm aware that, as a founder, he's obviously very interested in the success of his product. His mentality however carried over the acquisition and past inertia. Giving him the benefit of the doubt, I think his problem is that he's passionate.

And I don't mean the corporate lingo 'passionate', I mean the actual passionate. I strongly advise any passionate people to not seek to turn their passion into a job. Because it's a long journey full of suffering.

Your bosses will drive you insane. Your clients will drive you insane. Your coworkers will drive you especially mad. You will feel pain every time you will be asked to cut corners. No one will appreciate the finer details of your work. You will become the office insufferable twat. Passed every promotion.

The sweet spot is somewhere between "I don't hate it" and "I kind of like it". You can learn to like something if you do it long enough.
