About Jamie Siminoff, Founder of Ring
A lifelong inventor and mission-driven entrepreneur, Jamie Siminoff created the world’s first wifi video doorbell while working in his garage in 2011. That doorbell has since transformed into Ring, the whole-home security powerhouse that was acquired by Amazon in 2018 for over $1 billion.
Jamie continues to make neighborhoods safer as the Chief Inventor of Ring and has been active in impact investing and philanthropy through Shark Lake Explorations, his family office. His latest invention—his book—is a candid, behind-the-scenes account of how a scrappy garage startup called Doorbot turned into Ring, a household name and security brand now trusted by millions.
About Ding Dong
From a sweaty, near-catastrophic Shark Tank appearance to a billion-dollar acquisition by Amazon, Jamie Siminoff’s story of founding Ring is the ultimate underdog tale of invention, grit, and relentless reinvention.
While tinkering in his garage to solve missed deliveries at his own front door, Jamie hacked together a wifi video doorbell. His wife called it a safety game-changer. The Sharks called it a pass. After walking away from the TV show empty-handed and broke, Jamie rallied a ragtag team of Craigslist hires and turned rejection into rocket fuel.
Through near-bankruptcy, factory disasters, refusal to worry about the competition, and a maniacal focus on “the mission,” Jamie and his team started to notch wild (often surprising) wins, attract celebrity investors like Shaq and Richard Branson, and in record time built one of the most iconic consumer tech brands of all time.
Told with unfiltered honesty and humor, Ding Dong isn’t a polished success story; it’s a blueprint for anyone who’s been underestimated, rejected, or told to quit.
Because when opportunity knocks, there’s only one question: Will you answer the door?
