I moved back to Silicon Valley to work for Lehman Brothers. Lehman, of course, was later a victim of the global financial crisis, suffering an ignominious bankruptcy in September 2008. My job at the time, in addition to being an all-around grunt, was to help life sciences companies raise capital, go public, and make acquisitions. Those were noble things to do, but for the fact that despite the raging bull market in technology in Silicon Valley, the investor appetite for life sciences was largely dormant.
