John Battelle’s blog is reporting that Yahoo and Google are effectively setting themselves up as VC firms, sorta.

The logic is simple: if they see a promising company that’s in their space, they have the expertise to do a good due-diligence, and they also have the cash to snap them up before VCs get to them and raise their valuation.

In short: Google/Yahoo are getting startups for cheap by getting in earlier than VCs do.

Now, we don’t know how long this will last, but you could do a lot worse than identify some technology that Yahoo/Google will want and then building it “real” enough so that you get bought out.
