This guy turned his failure on 'Shark Tank' into a $28 million investment from Richard Branson
In September 2013, Jamie Siminoff went on ABC's "Shark Tank" in hopes of raising $700,000 for his company, DoorBot. He thought it was worth $7 million.
His company made a video doorbell that connected to your smartphone, so you could remotely see and talk to the person at the door through your mobile device.
