I'm not a fan of nascent bragging about killing your latest startup, leaving customers out in the cold without a good reason or advanced warning. Find a buyer or pivot, otherwise it's just flushing time, money and credibility down the drain.

For a first bootstrapped startup, a FNAC that doesn't require much overhead / support and can be built slowly for awhile is a starting point. It's not a proper startup, but it's something that puts founders and customers in less jeopardy.

(Startups proper are go big & fast or bust.)
