'Real' founders are fine -- we have a lower expected salary anyways but are probably extra employable. (Imagine who knows the most about contributing to a business!)
The issue is that we were the ones who convinced the people we sat down with to put their eggs in our basket. Investors put in their hard-earned money, employees devote their precious personal hours and "one shot", and customers (in B2Bs) put their own businesses on the line. A company is a social bedrock and we're ultimately responsible.
This stuff can certainly be rationalized away. Professional investors spread their risk and angels are often in it for the fun, employees get a bundle of a paycheck, lottery ticket, and personal responsibility, customers make business decisions, and everyone is getting a seat on the rocket. However, founders are human and part of that means having empathy.
Ironically, a lot of the stress that some founders experience comes from their own lack of transparency with employees. I don't doubt that many founders care deeply about their teams, but many are also so mortified at the thought of not being able to recruit and retain that they try to paint the most favorable picture of the startup's current state, conveniently ignoring facts that aren't so favorable.
Obviously, the information that founders can reasonably share with employees changes over time as a company grows, but at an early-stage startup, there's really no excuse for anything less than full disclosure. As the founder of such a startup, you must accept that you can't guarantee your employees continued employment, but you can promise them that you'll be honest about the company's state.
