Venture capital

Angels typically invest their own funds, unlike venture capitalists who manage the pooled money of others in a professionally managed fund.
In addition to angel investing, equity crowdfunding and other seed funding options, venture capital is attractive for new companies with limited operating history that are too small to raise capital in the public markets and have not reached the point where they are able to secure a bank loan or complete a debt offering.

Deal flow

Deal flow (or dealflow) is a term used by finance professionals such as venture capitalists, angel investors, private equity investors and investment bankers to refer to the rate at which they receive business proposals/investment offers.

An angel investor (also known as a business angel, informal investor, angel funder, private investor, or seed investor) is an affluent individual who provides capital for a business start-up, usually in exchange for convertible debt or ownership equity. Because innovations tend to be produced by outsiders and founders in startups, rather than existing organizations, angel investors provide, in addition to funds, feedback, advice and contacts.
The startup ecosystem consists of the individuals (entrepreneurs, venture capitalists, angel investors, mentors, advisors); institutions and organizations (top research universities and institutes, business schools and entrepreneurship programs and centres operated by universities and colleges, non-profit entrepreneurship support organizations, government entrepreneurship programs and services, Chambers of commerce) business incubators and business accelerators and top-performing entrepreneurial firms and startups.
