Quite a lot of books I want to recommend are already here. - Hard things about hard things - Good Strategy / Bad Strategy are a couple of books that can help here

If the purpose of this exercise is to improve your overall understanding, I would recommend something more fundamental than above (software-specific business books). Read some Macro Economics, articles around industries you are interested in (SaaS, Mobile, etc.) - especially historic ones which give you more foundational understanding.

Also, I strongly recommend not doing an MBA program if knowledge is what you seek.
