A few disconnected thoughts: * They own the business, not you. If you owned a part then you would be able to make decisions like spending resources on improving the codebase. In the end, it is up to them to run it, not you. * Businesses come and go, relationships stay. If you think the guy is a good boss stay in touch; even if your notice causes a lot of bad emotions and someone throws a drama fit, just treat it like a temporary thing and it will be -- call them back in two months to see how things are going and they won't even mention it. * Don't believe that you owe them any sort of extended stay. You can help their new hire transition via email support from your new place. If you agree to stay longer than 2 weeks, they are likely to delay the new hire by that much.
