I first met Dan at the little breakfast YC held for our newly-admitted class, right after interviews in May of 2008. I was so impressed with the strength of Dan's ideas, his natural charisma, and how much of a hustler he was. I still tell friends the stories I heard from him that day about how he worked the system in ways that I don't think even Dan would feel comfortable with me saying here. Dan worked all the angles, especially the ones that you and I would never even consider. He took crazy risks, often came out on top, and had a shit-eating grin the whole way. Dan was awesome. Throughout the summer, Dan and I would talk regularly about our companies, strategies, and how it was going. He had the rare mix of smart, incisive questions, and an easygoing manner that made everyone relax and smile. Jessica would always scold Dan and Tom for drinking too much beer in front of the speakers, and Dan would always charm his way out. Everyone was in stitches for his demo day presentations too. I remember hearing PG brag about feeling like he could just leave the TicketStumblers alone and they'd come up with something awesome without his help. Dan was an amazing guy, and I only saw a tiny fraction of his light. The world needs more Dans.
