What’s it like to pitch your dream on Shark Tank, get rejected on national TV in front of eight million people — and then turn that failure into a company Amazon later buys for more than a billion dollars. Ring founder Jamie Siminoff did just that. A serial inventor and entrepreneur, Siminoff joins us to talk about his new book, Ding Dong: How Ring Went from Shark Tank Reject to Everyone’s Front Door (out Nov. 10), sharing the messy, high-stakes, and ultimately inspiring story behind the company.

Now back at Amazon as a vice president leading Ring and the company’s home-security businesses, Siminoff reflects on failure, reinvention, and what comes next in the age of AI.
