Death of a Start Up
Advice: if you get a good idea, DROP EVERYTHING. Do it. Do it now. Don't sex, sleep, eat, drink, dream until it's done. Why? Because the moment you think of the idea the window of opportunity starts to close. Unfortunately for us, the window closed just as we were thinking about leaving private beta. Someone else had the same idea - and that person was Amazon. No way in hell can we compete with them, so we've closed the startup. Which, though disappointing, means we were definitely onto something. We wish, however, that we had just done it 18 months ago when we had the idea.
Ah well, back to the drawing board.
