For the launch of a site about the New York tech scene, we thought it would be fun to turn back the clock and look at who ruled the roost at the turn of the century. We took as our subjects the Silicon Alley Reporter 100 list from the year 2000, a bumpy patch for the dot-com kids. Hundreds of young public and private companies collapsed after the NASDAQ famously peaked at 5,048 on March 10 and then dove to 3,649 the next month, including the proto-social network theglobe.com, long-loading high fashion site Boo.com and abruptly-bankrupt webcaster Psuedo.com, whose founder Josh Harris is now an advice columnist for Betabeat. “What a difference a year makes,” editor Jason Calacanis’s letter opens. Some of these 100 Silicon Alley entrepreneurs were still flying high at the time of the list, some were hanging on and would rebound later, and others were still helming doomed companies. They were all here during the peak of the city’s tech scene, but where are they now?
