Venture capital is money invested by firms ('VCs') that use other people's money, raised by offering investors a chance to take part in a fund that is then used to buy shares in a private company. Because they are using other people's money, vs. angel investors, VCs can accept less risk, but they have more money to invest. They are seldom interested in early stage companies, except e.g. tech start-ups with already successful founders. They normally invest £1m+, have contacts and business experience to offer and require a seat on the board to ensure hands on participation in company operations.
