U.S. venture capitalists invested $21.8 billion in 2010, a 19.4 percent increase over 2009 and the first increase in venture investment since 2007, according to the National Venture Capital Association (NVCA) and PricewaterhouseCoopers Moneytree Survey. The growth in activity affected nearly every industry, particularly clean energy software and Internet-specific companies. Early stage investments, though not seed stage investments, grew by double-digits as did first-time financings. In addition to the gains in venture dollars, VC deals grew to 3,277, a 12 percent increase over 2009. Venture capital (VC) returns also have begun to improve for the 3, 5 and 10 year horizons, according to the Cambridge Associates and NVCA.
