An angel investor or angel (also known as a business angel or informal investor) is an affluent individual who provides capital for a business start-up, 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 to share research and pool their investment capital, as well as to provide advice to their portfolio companies. There are two types of Angel investors viz. Pure Angels and Supre Angels
Pure Angels are full time investors. These are typically the individuals with some entrepreneurial and investing experience, many of who led to the formation of angel networks.
Super Angels are entrepreneur-turned-investors, known for their signalling effect and being a major source of deal flow for VC funds making early stage bets. Super Angels are pet favourites for a crop of start-up founders.
