Ring stands as one of the most successful businesses to emerge from Shark Tank. The company's CEO mentions that he trained for his presentation with the dedication of an Olympic competitor.

Jamie Siminoff’s Journey from DoorBot to Ring’s Billion-Dollar Success

Jamie Siminoff, the creator of Ring, may have initially found his way onto Shark Tank through a stroke of luck, but the intense preparation he put into his pitch was nothing short of extraordinary.

Just over a year after launching the first version of his video doorbell under the name DoorBot, Siminoff decided to take a bold step and apply for a spot on the renowned business reality show.

That year, more than 30,000 hopeful entrepreneurs submitted applications to appear on Shark Tank. Siminoff considered himself fortunate not only to be selected but also to make it onto the broadcast. However, he told Fortune that capitalizing on this opportunity required far more than luck alone.

“We were fortunate, but plenty of people get lucky and don’t make the most of it,” Siminoff reflected.

Appearing on the show was just one of several crucial moments when Siminoff seized an opportunity that would ultimately help transform Ring into a company valued at over $1 billion.

How Siminoff Prepared for Shark Tank

To get ready for his appearance, Siminoff recreated the Shark Tank set in his backyard, enlisting his neighbors to play the role of the sharks and challenge him with tough questions.

“Once we were accepted, I treated it like training for the Olympics,” Siminoff explained. “I was determined to be as prepared as possible.”

He also meticulously studied past episodes of the show, taking notes and drafting hundreds of possible questions he might face.

“I focused on contestants whose presentations matched the image I wanted for our company,” he said, watching their pitches repeatedly to learn from their successes.

Despite his rigorous preparation, only Kevin O’Leary—famously known as “Mr. Wonderful”—extended an offer. Siminoff had requested $700,000 in exchange for a 10% stake in his company, but O’Leary countered with a $700,000 loan, a royalty agreement, and a 5% equity share. Siminoff ultimately declined the deal.

In 2018, Jamie Siminoff returned to Shark Tank as a guest shark, sitting alongside Kevin O’Leary, the only investor who had made him an offer during his original pitch.

Although he walked away without a deal, Siminoff’s performance impressed O’Leary, who later described him in a CNBC interview as “a really good salesperson.”

Ring’s story didn’t end there. In 2018, Amazon acquired the company for approximately $1 billion, marking one of the most notable missed opportunities in Shark Tank history. That same year, Siminoff returned to the show, this time as a guest shark himself.

“It sounds unbelievable, but my ambition was always to build the best company and appear on Shark Tank. That was my dream, and I worked hard to achieve it,” Siminoff shared.
