Early Life

Jamie Siminoff was born on October 18, 1976, in Chester, New Jersey, United States. He hasn’t revealed the identities of his parents, siblings, or other close family members.

Siminoff attended West Morris Mendham High School. He later graduated with a Bachelor of Science degree from Babson College, majoring in entrepreneurship.

Career Information

Jamie Siminoff launched his investment career shortly after graduating from Babson College. He set up a number of tech companies, including a Voice over IP startup in Bulgaria, an email de-clutter service known as, and a voicemail-to-text converter called PhoneTag.

Although these businesses broke even, they fell short of Siminoff’s greater expectations. Therefore, he folded them and headed back home to think up fresh ideas. It was then that he conceived the idea of Ring (originally known as Doorbot), a smart video-enabled doorbell that could be operated right from the homeowner’s smartphone.

Siminoff came up with Doorbot as an innovative way of preventing home invasions by fooling a potential burglar into thinking that the homeowner was home. Homeowners would be able to remotely see whoever was at the front door and possibly communicate with them.

Convinced that his idea was attractive enough, Jamie Siminoff embarked on a series of funding campaigns. He raised $364,000 through crowdfunding in 2013. The same year, Siminoff pitched his innovation on ‘Shark Tank.’ He received a loan proposition from investor Kevin O’Leary but wasn’t convinced it was what he needed to launch his startup.

Siminoff walked out of Shark Tank disappointed but undeterred. He utilized the funds received so far to launch his company and renamed it Ring. It wasn’t long before the gamble paid off.

Ring began to generate millions in annual revenue only months after its establishment. It also attracted investment from renowned entrepreneurs, including Sir Richard Branson, Goldman Sachs, and Qualcomm Ventures who pumped about $200 million into the company.

On February 27, 2018, acquired Ring for between $1.2 billion and $1.8 billion.

Jamie Siminoff has a net worth of $350 million as at November 1, 2022.

As you might expect, a huge chunk of Siminoff’s wealth comes from his investment in Ring. The actual amount paid to buy Ring remains unclear. But what we know is that Siminoff was the company’s majority shareholder as at the time of this historic transaction. And even if you take a conservative purchase price of $1.2 billion and assume that Siminoff’s share in the company was 51%, you realize that the deal brought him a jaw-dropping $600 million windfall pretax.

Jamie Siminoff’s current net worth is also the sum total of earnings from other ventures undertaken before founding and after selling Ring. These include his and PhoneTag startups.

Lessons from Jamie Siminoff

1. Creative inspiration can come from anywhere

Jamie Siminoff conceived the idea of Ring while working in his garage. A garage is probably the last place such an ingenious concept could ever come from.

2. If one idea fails, abandon it and try something else

Siminoff invested in many startups before founding Ring. Although his initial projects broke even, they proved unsustainable in the long run. Siminoff had no choice but to abandon them and try out something new.

3. Never make rush investment decisions

Jamie Siminoff had the rare opportunity of pitching his Ring startup to sharks on ‘Shark Tank.’ He was so convincing that he received a loan proposition from Kevin O’Leary. But upon weighing his options, Siminoff reckoned that the investment offer wasn’t commensurate with the startup’s growth potential. He declined the proposition and went on to self-launch the company. As they say, the rest is history.

Famous Quotes by Jamie Siminoff

• I liked solving problems, and I liked building products. For me, the most frustrating thing was that I kept building these products that no-one used at scale. An inventor is an artist. You want people to see the artwork and talk about it.

• If you want to be in the business of having your own company and being able to succeed in this way, welcome to the failure game. You’re going to get hit with a lot of things. You’ve got to be able to just move on and do it.

• If you’re building a startup, the amount of decisions you have to make is extreme, and you can’t have a meeting on every decision. You have to make a lot of decisions fast. I think it’s true that making no decision is worse than making a bad decision. Indecision is a really bad thing.

• Once you’re in a business, you can’t turn right and left. You’re on a railroad track. The train doesn’t get to decide where it’s going. And I wanted to be nimble. It was myself, and two interns in my garage. And we just started tinkering.

• One of my strengths is that I make a lot of gut calls, but I make them off of data. I’m not good at a lot of things. But one of the things I’m good at is taking all the inputs that are around me, and being able to spit out decisions quickly based on that.
