I interviewed with these guys back in September of 07 and before they could get back to me, I got an offer I couldn't turn down. These guys were 'operating in stealth mode' back then, but they really had a solid focus and vision.<p>It is amusing though because over the following two years, whenever a Software Engineering position was available for them, I would get inundated with calls from half a dozen or so headhunters. It got to the point that when the phone rang after the first 'position available' call, i was able to tell the hunter that they were trying to fill a spot for "invite media" and it became a bit of an entertaining sport for me catching them off guard.
I went to Penn with the founders, though I didn't know them personally during my time there. I did meet Mike Provenzano, one of the cofounders, earlier this year though. He's a great guy and I knew upon meeting him that he was building something great at Invite. Congratulations to the entire team.
