Investments as a segment have always been there in the form of land, gold, stocks, mutual funds and investing in other people's businesses/startups as an asset class. Angels are those who have additional cash in hand and who want to invest it in other vehicles for rewarding arrangements. While earlier investments in other people’s businesses were made with lower risk appetites, in today’s time, the market has opened up and so has the risk appetite. But the startup investment asset class is a different ball game. Very rewarding but very risky, if essential elements are overlooked.
