Venture investments declined in 2012

Capital-intense sectors like clean technology and life sciences were among the hardest hit, according to the MoneyTree study released Friday. It was conducted by PriceWaterHouseCoopers and the National Venture Capital Association, based on data from Thomson Reuters.

In all of 2012 startup investments fell 10 percent to $26.52 billion from $29.46 billion. There were 3,698 deals completed, down 6 percent from 3,937 in 2011. Venture investments also declined 13 percent in the final quarter of the year, to $6.4 billion from $7.38 billion a year earlier, though the number of deals was the same in both quarters at 968.

"General economic uncertainty continues to hinder capital investments, and venture capitalists are no different," said Tracy T. Lefteroff, global managing partner of the venture capital practice at PwC U.S. "As the number of new funds being raised continues to shrink, venture capitalists are being more discriminating with where they're willing to place new bets. At the same time, they're holding on to reserves to continue to support the companies already in their portfolio."
