Way of the future may be sidecar funds that are for passive investors interested in angel investments. The sidecar fund invests automatically in all the deals of the angel group to which it is attached. This is a good way for the angel group to be assured of committed capital - especially during economic downturns where members may be less free with cash - and also allows external investors to achieve a diversified exposure to start up investments with a relatively small capital commitment. This is a good way for newbie angels to learn more about the angel group and their investment process - and if they like they may later choose to join the group and become more active "mentor" investors.
