Excellent article in Crain's Feb. 28 issue, Silicon Prairie Revival: Local web-tech start ups are drawing a lot of attention and loads of cash from venture-capital firms looking for the next Groupon. Great photo and interviews with innovation cheer leaders JB Pritzker, Matt McCall, Mike Sands, Lon Chow (he's on nine company boards; who knew?) Sam Guren, plus a lengthy and helpful list of Chicago's biggest investment bankers. Good reading.
