I invested in a start up company as an angel investor.
I would like to know who the other angels that invested in the company are. Can I do that?
This should be a necessary part of your due diligence prior to completing your investment. Who else has invested, how much has been invested over what period of time? You should see a cap table and know what investment instruments have been used for prior investments (equity, either common or preferred; convertible debt/terms; debt/terms) before you invest, but if you already have, you should be able to get this information. My best advice? Ask!
