Hugh Pickens writes writes: "With the 'fiscal cliff' just weeks away, Chris O'Brien writes that venture capital fundraising in silicon valley is down, the amount invested is down, the number of folks investing in venture capital is down, and the number of VC firms and partners are down. "The people I talked to in the industry sounded grim even as they tried to make the case for optimism," writes O'Brien. "Still, it remains difficult to identify a clear path for turning things around for the battered venture capitalists who make Silicon Valley hum." So what's wrong with the VC industry? The problems are many and complex but they can be boiled down to one thing: Not enough exits. For the size of venture capital being raised and invested, there simply aren't enough initial public offerings of stock or mergers and acquisitions to generate the returns that funds need. Venture insiders blame the global economic uncertainty. They believe that is part of the reason that giant corporations, which have amassed huge piles of cash, are just sitting on it, rather then using it to acquire startups. "The numbers are way down," said Ray Rothrock, a partner at Venrock. "All these companies with these fantastic balance sheets, and nobody is really buying anything. With all the uncertainty they're facing with the economy and taxes, buying little companies is way down on their list.""
