I list some my failed startups in my HN profile. Chronologically: 1337Tech(2005) - a tech review blog ala AnandTech. Tear downs, detailed reviews and the like.

I list some my failed startups in my HN profile. Chronologically: 1337Tech(2005) - a tech review blog ala AnandTech. Tear downs, detailed reviews and the like. Failed because we couldn't keep up a schedule edgeyo(2009-2012) - a matching marketplace for investors and startups - think AngelList + SecondMarket + KickStarter. Ran into some regulatory concerns, and eventually we decided to just close shop because we couldn't put enough time and effort into working past some of those issues. SpellTrade(2010) - a options exchange for Magic the Gathering cards. Supply problem caused a bootstrapping problem (our partner couldn't put up enough to supply the cards for bootstrapping). Closed before we even made a sale. Strangers For Dinner(2012) - a matching market for strangers - one party will host a dinner party, and 5 other people will show up as guests. We managed to match about 50 parties in total before the number of people signing up as guests far outnumbered the people wanting to host. Also, people were not likely to host a second time. Couldn't get around this problem, plus the team had other commitments, so we shut it down. 2 out of three of the startups I had in the last 4 years or so were killed because they eventually became zombie startups. We couldn't get traction.
