I'm not saying that it's impossible, but it's the sort of thing that requires a technical cofounder with a fairly clear vision of what they want to achieve and with the knowledge and experience doing so.

I worked until recently at a traditional engineering industry focused startup company which decided to deploy a Python application on-premise to a big customer. From the use case it was very clear to me that an on-prem deployment of the software was likely to be on the cards, but there was nobody there in the non-technical leadership to say at the beginning "wait a second, maybe we shouldn't write this in Python for this use case".

Don't, unless it's 100% critical for success. You have to run super lean as a startup. You don't have time for ANYTHING except validating your business.
