The graphic below gives a sector breakdown of US VC investment for Q1 this year (thanks to Udemy) and as you can see all the interest is in social and advertising. Perhaps not surprising given the LinkedIn IPO, Groupon filing, progress at Facebook and rude health of the online advertising market.
Our current focus at DFJ Esprit correlates pretty well with this chart. Smart money managers are of course always looking to stay ahead of the pack and the figure which leapt out at me here was the 3% going into healthcare. I would expect that number to leap up over the next five years or so.
