Venture capital involves professionally managed pools of equity capital that are invested in small, growing companies. These pools come from wealthy individuals and institutions. Venture capitalists take an equity stake in companies and actively monitor their progress. There are various types of venture capital firms, including private firms, small business investment companies, and corporate venture arms. The venture capital process involves preliminary screening of business plans, negotiating terms, extensive due diligence, and final approval if the venture capitalist decides to invest. Venture capitalists specialize in certain industries and stages of financing like early stage funding or expansion. Entrepreneurs should research which firms focus on their industry or idea.
