Key Takeaways

Siminoff’s Doorbot prototype paved the way for Ring’s official launch in 2014. Despite a rejection on Shark Tank, Ring was acquired by Amazon for about $1 billion. Now, Siminoff continues to work closely on the product, with a focus on AI.

This as-told-to story is based on a conversation with Jamie Siminoff, founder of Ring and author of Ding Dong, which explores how he turned his garage-built prototype into a video doorbell that led to a $1 billion acquisition by Amazon.

It was about understanding that by being connected to the world through our phones, we could approach home security in a totally different way. That changed everything. We set out with the mission to make neighborhoods safer.

The Kickstarter pre-sale and ‘Shark Tank’ appearance

A couple of years later, we ended up doing a pre-sale on Kickstarter, which gained traction, and took the product on Shark Tank in November 2013. I consider Shark Tank the Olympics for entrepreneurs and inventors. It’s a huge opportunity for credibility and awareness. So I trained as if I were an athlete preparing for the Olympics. I built the set in my backyard and had neighbors come over and ask me questions.

Producers had told me to get ready for the Sharks to talk over each other. It’s a lot to manage — and it can’t be boring if the episode’s going to make it on air. You could have the best........
