In 2011, Siminoff invented a world-first in his garage, no less – a wireless video doorbell he called DoorBot. Fast forward two years later, and Siminoff was on the ABC hit show Shark Tank, with a more evolved product he now called Ring. Ultimately, all the sharks passed save for Kevin O’Leary, but Siminoff left the show without accepting his offer.
