Juicero — The $400 WiFi Juicer

With $120 million raised from investors like Kleiner Perkins and Google, Juicero stands as the most wasteful startup in history. The WiFi-connected machine squeezed proprietary $8 bags of chopped fruit, but users quickly discovered that hand-squeezing the bags yielded identical juice in seconds—no $400 appliance required. This 97% cheaper method exposed a hubris that outperforms #2 Pets.com in sheer absurdity, because at least Pets.com targeted an untested market rather than a solved problem.
