I think this is the main reason that, pretty much, only technical founders seem to succeed at finding good exits (I know there are exceptions), they're very aware of this issue.

I have worked with non-technical founders who just don't understand that concept of a mythical man-month and technical debt. Unless you've lived through it, it just sounds like engineers whining, not a valid business liability. All the non-technical founders I've worked with fall into the trap of catering to their board at all costs.
