Interesting story on how the crunch in the financial markets is impacting the availability of draw-down cash at VC backed startups.

 The national credit crunch is starting to hit Silicon Valley start-ups. We’ve heard that venture-backed companies with Comerica money market accounts have had their accounts frozen, and when we asked Comerica spokesperson Sara Snyder, she didn’t deny it.

Snyder didn’t explicitly confirm anything either, but pointed to this New York Times article about problems in the auction-rate note market (where Comerica has invested its money market accounts) and said, “At Comerica, we are working with customers on a case-by-case basis to assist them with their liquidity needs.” (Venture Beat)
