ANECDOTE

Rejected On Shark Tank But Too Far In To Quit

Jamie Siminoff recounted the Shark Tank pitch where he offered 10% for $700K and left feeling deflated after being told it couldn't be a big company.
Despite Mark Cuban saying he didn't see it scaling, Jamie stayed committed because he was already too invested to quit and had strong sales momentum.

INSIGHT

Market Framing Killed The Early Pitch

Investors framed Ring as a doorbell company and calculated TAM from the doorbell market, which looked too small to justify investment at the time.
Jamie saw Ring as a security platform, but that reframing only emerged later when customers already showed security use cases.

A Note from James:

Imagine going on Shark Tank in front of Mark Cuban, Mr. Wonderful, Lori Greiner, Robert Herjavec, and the rest of the Sharks. You’re offering 10% of your business for $700,000, which values the company at $7 million. They all say no. Then, a few years later, Amazon buys your company for a billion dollars.

That's gotta feel really good, and that's the experience of our next guest, Jamie Siminoff.

Jamie built the company behind the video doorbell that lets you see who’s at your door—Ring—and helped turn a simple household object into a home security platform. He went on Shark Tank in 2013, didn’t get a deal, kept building anyway, and eventually sold Ring to Amazon.

Jamie has a book coming out right now called Ding Dong: How Ring Went from Shark Tank Reject to Everyone's Front Door. What really impressed me about Jamie was the simplicity of all his business ideas, since this was his fourth business. A doorbell you can answer from your phone. A way to turn voicemail into text. A tool to unsubscribe from unwanted emails. The kind of ideas that make people say, “Someone must have already done that.” But we talk about this very thing and how critical it is for entrepreneurs to get over these feelings of like, "Oh, I can't do that."

That’s the lesson. Sometimes the obvious problem is still unsolved. And sometimes the person who wins is the one naive enough—or stubborn enough—to fix it anyway.

Episode Description:

James sits down with Ring founder Jamie Siminoff to talk about one of the great modern startup stories: a rejected Shark Tank pitch, a product investors dismissed as “just a doorbell,” and an eventual billion-dollar acquisition by Amazon. But the episode is not just about the sale. It’s about how entrepreneurs see problems before markets know what to call them.

Jamie explains why investors misunderstood Ring at first. They looked at it as a doorbell business, not a home security company. That framing made the market look tiny. But customers were already showing something different: they wanted to know who was at the door, feel safer, and use video in a new way around the home.

The conversation also moves into Jamie’s earlier companies, including PhoneTag and Unsubscribe.com, and what those taught him about declining markets, customer behavior, and the difference between a clever product and a durable business. From there, James and Jamie talk about AI, why software is easier to build than ever, why that does not make startups easy, and why simple pain points still matter.

What makes this episode useful is Jamie’s clarity: don’t start with the technology. Start with the problem. If something is broken, fix it. And don’t automatically assume that because an idea sounds obvious, someone has already solved it well.

What You’ll Learn:

Why Ring looked like a tiny doorbell business to investors—but became a massive home security company.
What Jamie learned from being rejected on Shark Tank while already showing real sales traction.
Why simple ideas are often dismissed precisely because they seem too obvious.
The difference between being an “inventor entrepreneur” and a market-first operator.
Why declining markets can make even beloved products hard to scale.
How AI changes the cost of building software, but not the difficulty of building a valuable business.
Why Jamie believes entrepreneurs should focus on problems and solutions, not technology for its own sake.
