Find out how many people are working for the startup and their backgrounds. This is super important to do either as research before or after, to find out if you are going to be working with truly A-players. Overlooking this aspect might be ok in the short run but as with many startups, people do get laid off at some point (or the idea fails to take off) so to get maximum benefit during your time, expose yourself to excellent colleagues who will grow your skillset.
