Below is a brief set of rules to follow that will help you be a great angel. Let me know if I missed any on Twitter! 1. Always put the startup first. This seems like a "no duh" statement but there will be times when your interests as an angel diverge from the startups interests. If a conflict of interest arises (between yourself and the startup and other thirds parties - e.g. VCs, other startups, potential acquirers etc.) always err on the side of doing the right thing for the startup.
