I have been following Spotify, the hot startup of the moment, from the days when founder Daniel Ek used to share office space with one of our neighbors on Pier 38 in San Francisco. Since then, we have moved to new offices and Daniel’s company has raised tons of money, is valued at a rumored $250 million, has become a media darling and, most importantly, a consumer favorite. It now has more than 100 employees and 6 million users. These are signs of a startup barreling its way towards success. But apparently that wasn’t enough for Andreas Ehn, Spotify’s chief technology officer, who has left the company. Yesterday was his last day on the job. Whenever one of the early employees leaves a hot startup, the first question that pops to my mind: What gives? Time to hit the phones!
