Angel investors are individuals who offer promising startup companies funding in exchange for a piece of the business, usually in the form of equity or royalties. While figures vary on an annual basis, as recently as 2017 angel investors put approximately $25 billion into 70,000 companies.
Angel investors may or may not be accredited investors, a classification given only to investors with very high incomes or net worths. With the passage of 2012’s Jumpstart Our Business Startups Act, the criteria for startup investors was expanded to include more everyday retail investors, including crowdfunding campaigns.
