This strikes me as weird. He could literally call up any VC firm in the world right now and tell them he'll point his endpoints to a new backend if they give him some money. He doesn't even have to be involved in that part of the business. Just let them figure it out (with their own choice team) and he'll re-rig the app to it.

This is still an pretty substantial amount of effort, and a lot of risk. I really don't blame anyone for not doing this, especially if they also have another successful business that they are running already.
