From being turned down on Shark Tank to building a billion-dollar brand acquired by Amazon, Jamie Siminoff’s story is a testament to the power of resilience, reinvention, and staying true to your mission. Drawing from his new book, Ding Dong: How Ring Went From Shark Tank Reject To Everyone’s Front Door, Siminoff takes audiences inside his rollercoaster journey of near-bankruptcy, breakthrough innovation, and building a movement rooted in purpose. He reveals practical strategies for transforming setbacks into momentum, leading with conviction, and creating products that make a real impact, proving that sometimes the biggest “no” can spark your greatest success.

Jamie Siminoff has been called “the billion dollar deal that got away” by the sharks on Shark Tank. After walking away from the show without an investment, Jamie led Ring to become a trusted, whole-home security company – eventually landing a $1 billion sale to Amazon.

Above all, there is one critical reason for the company’s success: a focused mission. Even when faced with the possibility of running out of funding, everyone at Ring was driven by the same goal of making neighborhoods safer.

Drawing from real examples throughout his career, Jamie demystifies how to implement mission-driven strategies that can transform any organization. The result is a stronger culture, increased innovation, and measurable growth that translates directly to the bottom line.
