Definitely some hot takes:
Shutting down and giving up is really hard. Founders may have spent many years of their lives on a company that is not going to work. But rather than spend another 2 or 4 years waiting for the bank accounts to drain through multiple layoffs and venture debt draw downs it might be better to accept reality and throw in the towel.
For a founder (and their employees), those 2+ extra years may be amongst the potentially most productive years of their lives. The opportunity cost of not going to work on something better is too high.
Is this possible without a tarnished reputation?
