The term "ANGEL" originally comes from England where it was used to describe wealthy individuals who provided money for theatrical productions. In 1978, William Wetzel, then a professor at the University of New Hampshire and founder of its Center for Venture Research, completed a pioneering study on how entrepreneurs raised seed capital in the USA, and he began using the term "ANGEL" to describe the investors that supported them.

Early-stage investing carries a high degree of risk. To help minimize that risk, the Keiretsu Forum members have developed a thorough and comprehensive due diligence process that is applied to all companies prior to member investment. The due diligence process is now available in The Keiretsu Forum Due Diligence Handbook, which represents more than a decade of knowledge and best practices vetted by over a thousand Keiretsu Forum investor members world-wide.

Like all investing, startup investing benefits from a disciplined approach. The Keiretsu Forum Due Diligence Handbook offers investors a framework to use while considering investments. Research clearly shows that investments made following a thorough due diligence process have significantly better outcomes than those made following less due diligence. 

Keiretsu Forum Southern California is pleased to offer our member-designed Due Diligence Handbook free of charge as an iBook to benefit startup investors and entrepreneurs around the world. We hope this resource will serve as a valuable tool in supporting your own due diligence efforts.
