Or they miss the point when overthinking the whole code for the program/website. Get it done. Start finding customers.

The worst code I worked with was at travel agency startup and they are REALLY successful now. It was REALLY REALLY bad and hard to maintain. The owner of the business just said: well, bugs happen. But when a customer (not too many of course) encounters one, they probably call the helpdesk. Sounds stupid, worked great, business wise.

4 years later, I am sure they still have problems with the crappy code, but the business is fine!
