Earlier quoted context omitted.
I don't think THIS was a talent acquisition so much as a super successful game, so successful Zynga couldn't rip it off and kill it, but there are definitely large talent acquisitions in recent history: * Powerset. ~$100mm, July 2008, to Microsoft. * Friendfeed, ~$50mm, August 2009, to Facebook. * Slide, $228mmm August 2010, to Google. (Takeaway: sell your company in the summer.)
Powerset and Aardvark both seem like pretty compelling responses. A 9-figure talent acquisition! I concede my case.
There's probably a good business model in being an "academy startup" which both shoots for the moon AND is a great place to work, builds skills, and can do a talent sale (or tech sale, maybe) if the product is unsuccessful, building that into the company from the start. That's probably what I'd do, especially if it were based outside the bay area and maybe strongly allied with a great school but lacking other good local employers (Waterloo, CMU, etc.)
