Seed money
Seed money, sometimes known as 'seed funding or seed capital,' is a form of securities offering in which an investor invests capital in exchange for an equity stake in the company. The term seed suggests that this is a very early investment, meant to support the business until it can generate cash of its own (see cash flow), or until it is ready for further investments. Seed money options include friends and family funding, angel funding, and crowdfunding.
