Jamie Siminoff

Innovation speaker Jamie Siminoff is the founder of Ring and a vice president at Amazon, where he leads Amazon Home Security across Ring, Blink, Amazon Key, and Sidewalk. A lifelong inventor and entrepreneur, he is best known for building Ring from an early prototype into a category-defining home security brand used by millions of households.

From Garage Prototype to $1B Acquisition

Siminoff’s journey is rooted in persistence and an unusually clear product vision. He originally pitched his video doorbell concept on Shark Tank and left without a deal. Instead of treating that moment as a dead end, he used it as feedback, rebuilt the product, refined the customer promise, and pushed forward through repeated funding pressure and operational constraints. Ring went on to become a leading whole-home security platform and was acquired by Amazon in 2018 in a deal widely reported at around $1 billion.

Leading Innovation Inside Amazon

After the acquisition, Siminoff continued to lead Ring inside Amazon, helping expand the product line beyond the doorbell into cameras, lighting, alarms, and neighborhood-focused features designed to improve everyday safety and awareness. He departed Amazon in 2023, then returned in 2025 to take on broader responsibility for Amazon’s home security portfolio. His return reflected a renewed emphasis on founder-led product thinking and faster innovation, including accelerating practical applications of AI and creating experiences that work seamlessly across devices.

Bestselling Author of Ding Dong

In addition to his work in home security and product innovation, Siminoff is the bestselling author of Ding Dong, a candid behind-the-scenes account of how a scrappy garage startup originally called Doorbot became Ring, a household name trusted by millions. The book offers a rare founder-level look at what it really takes to build, fund, scale, and ultimately sell a company, including the difficult decisions, setbacks, and moments of reinvention that shaped Ring’s trajectory.

Themes and Speaking Style

Across every chapter, Siminoff has been driven by a consistent mission: making neighborhoods safer while building technology that customers actually trust and use. His leadership experience spans invention, product-market fit, scaling teams, and navigating the transition from startup to global platform inside a large organization.

As a speaker, Jamie Siminoff is direct, energetic, and highly practical. He shares hard-earned lessons on turning rejection into momentum, building mission clarity that aligns teams, and leading innovation at speed without losing focus on the customer.
