Angels are investors who provide funding to startups after friends and family investments. They seek ideas that fill large market gaps and entrepreneurs who are passionate and proven. Angels expect entrepreneurs to know every detail of their idea, market, and execution strategy. For angels, success relies on the entrepreneur's ability to execute their vision. If funded, angels want active involvement to promote investment success and control risks. Their goal is for startups to be sold at 3-30 times their initial investment within 5-7 years.
