According to the Angel Capital Association, an angel group or angel network is individual angel investors joining together with other angel investors to evaluate and invest in entrepreneurial companies. These angels typically pool their capital to make larger investments. Some characteristics of angel networks are: meeting regularly to review business proposals, deciding collectively whether to invest or not, and working together to conduct due diligence to validate the plans, statements and history of the companies founding team, Between 10,000 and 15,000 angels are believed to belong to angel groups in the U.S. Angel groups also sometimes co-invest with other angel groups, individual angels and very early-stage venture capitalists to make larger, aggregate investments.[1]
