Maybe that's not as unlikely a prospect (or as bad an idea) as you might think. Do people know if there are relatively small idea-exploration pots of money (VC, angels, subsidies, startup and govt programmes) available in Europe/UK whereby a sufficiently well-qualified initial idea/plan, well-advised small founding team, and initially tested model can go to be funded for PMF exploration without being defocussed into hawking, door knocking and/or being dependent on 'who you know'?

Is this representative of how many Europeans think about technology startups? If so it's very revealing. You have to be willing to take lot's of bets tobhave any chance that some of them will take off and transform your job market, your economy, or how you live. If you only do things that are sure things guess what... stasis.

If you have a culture that denigrates failure rather than one that celebrates proactively trying to learn from it as this postmortem aims for then you're just going to be stuck
