In 2013, Jamie Siminoff appeared on ABC’s Shark Tank to seek funding for a smart doorbell he called DoorBot. He went away without any money, but the publicity helped him bootstrap his gadget and the startup behind it. Under the name Ring, that doorbell--which lets you conduct video calls with people at your doorstep even when you’re not at home--has become a smart-home hit: In November 2017, the company, now valued at over $1 billion, sold $22.5 million of them in just one day on QVC.
Now the company is building out a whole do-it-yourself security platform, including cameras sporting their own spotlights and floodlights. Ring Alarm will be shipped to customers in the spring of 2018.
Ring’s aspirations to help fight crime go beyond securing individual households. A feature in its smartphone app lets owners share video of suspicious activity captured by their cams with other folks in the surrounding vicinity, so questionable characters can’t roam a neighborhood at will.
