What would you think if a prospective hire agreed to accept a position on the condition that he be allowed to make an angel investment in the company? This is SO not my world, but since comments so far have been on the negative side: I can't actually imagine what the downside is in asking. They will either say yes or no. If they say no, you presumably have the choice of accepting the employment anyway or walking away. Provided all the negotiating is done courteously, I'm not sure what the problem could be. I guess there is some scenario whether they are so shocked and appalled by you asking (an Oliver Twist moment) that they would withdraw their employment offer completely, but would you want to work for them if they are that touchy?
