What is an angel investor?

Angel investors are individuals or groups who invest in early-stage or startup companies in exchange for an equity ownership interest. Finding an angel investor is only half the battle, though. Once you connect, you’ll have to successfully pitch your company to secure funding. 

Often, but not always, angel investors are accredited by the Securities Exchange Commission (SEC). To be accredited, angel investors must have either:

Annual earnings of at least $200,000 per year over the past two years and projected similar near-future earnings. This annual salary minimum increases to $300,000 if the angel investor files taxes jointly with their spouse.

A total net worth of at least $1 million.
