The biggest issue I've found with angels and especially super angels is that their fingers are in so many pies, that very often they're already fingering the same (or a very similar) type of pie that you're offering. You'd want to know exactly what they have a stake in before making an approach, yet often that information is hard to find (or purposely concealed.)<p>Overlapping feature sets. Conflicts of interest. Picking the winners. Contrived rejections. Leaks. Angelgates. Portfolio loading. Brain picking.<p>Buyer beware in my view.
