I feel like the problem this startup is going to run headlong into is that air source heat pumps are literally just air conditioners, and while they may be less common in parts of europe they are still common and simple enough to install that most installers already know how to do it, their companies nuts gouge on prices.

This makes the talk of the startup creating specialized schools seem odd, unless they specifically want to foucus on something like geothermal systems, but thouse systems require space around the building even if using vertical shafts and major renovation work to the building to replace the common steam boiler systems with underfloor or central forced air, which is why they are almost exclusively used in new build construction not renovation.

All this means that I suspect startups either built to solve the wrong problem, or else isn’t working with the right tech to switch exsisting buildings off gas anytime soon.
