Amy Cosper, the editor-in-chief of Entrepreneur Magazine, swung through Boulder recently and interviewed me, Scott McDaniel & Christian Vaneh of Survey Gizmo, Ari Newman of Filtrbox (recently acquired by Jive Software), Todd Vernon of Lijit Networks, and Tim Enwall of Tendril Networks. Unlike my two hour TWiST interview with Jason Calacanis, these are all short (less than three minutes each), punchy, and give you a great feel for some of my favorite Boulder entrepreneurs.
