Angel Fund

An angel investor (aka “angel”) is an affluent individual or private entity who provides capital for a business start-up and early stage growth, usually in exchange for convertible debt or ownership equity. A small but increasing number of angel investors organize themselves into angel groups or angel networks – commonly called “angel funds” – to share research and pool their investment capital, as well as to provide advice to their portfolio companies.
