Key Highlights
- Jamie Siminoff pitched his smart doorbell, DoorBot, on Shark Tank, seeking $700,000 for 10% equity.
- Despite a promising pitch, DoorBot (now rebranded to Ring) did not receive a deal on Shark Tank.
- The company was acquired by Amazon in 2018 for around $1 billion.
Imagine pitching your startup idea on Shark Tank, walking away with no deal, and then becoming part of a billion-dollar acquisition.
That’s exactly what happened with DoorBot (now called Ring). Founder Jamie Siminoff appeared on Season 5 of Shark Tank in 2013, seeking investment for his Wi-Fi doorbell camera device.
Siminoff conceived the product when he realised one day he couldn’t hear his front doorbell ring—so he built a Wi-Fi video doorbell so he could answer from his smartphone.
Years later, Ring was acquired by Amazon and has grown into a major home-security brand.
We’ll dig into what’s happened since the Shark Tank pitch, its net-worth today, and what entrepreneurial lessons can be drawn from Jamie Siminoff’s journey.

Net Worth: How Much Is Doorbot/Ring Worth Today?
When Ring was acquired by Amazon in 2018, industry estimates placed the value at about $1 billion. Since then, as part of Amazon’s devices & services ecosystem, Ring’s individual valuation is not publicly separated.
But we can infer that its integration into Amazon’s smart-home portfolio has given it substantial scale and revenue. For example, some sources note early revenue of “$274 million a year” for Ring around 2022.
At its Shark Tank valuation (~$7 million) and acquisition (~$1 billion), that represents over 140× growth in value. The dramatic jump reflects market demand for smart-home security, Amazon’s distribution power, and Ring’s expansion of product lines (doorbells, cameras, alarms).
The company faces various challenges around privacy and regulatory issues.
Jamie Siminoff Net Worth
Jamie Siminoff, the founder of Ring, is estimated to have a net worth of about $300 million as of 2025.
His wealth primarily stems from Amazon’s $1 billion acquisition of Ring in 2018, after he famously pitched the idea on Shark Tank in 2013 and was rejected.

At the time of the sale, Siminoff reportedly owned about 10–15% of the company, earning him an estimated $110–150 million payout before taxes. He also received a portion of the payment in Amazon stock, which has appreciated significantly over the years, further increasing his net worth.
Beyond Ring, Siminoff continues to invest in and advise startups within the tech and smart-home sectors.
After serving as Ring’s CEO for several years post-acquisition, he later became Chief Inventor at Amazon’s subsidiary and has since launched new ventures like Haven, a privacy-focused home security company.
DoorBot Shark Tank Pitch
Siminoff pitched DoorBot (now Ring) as a solution for homeowners who miss visitors or deliveries when they’re not at home. The device allowed smartphone-connected video doorbell interaction—see who’s at your door and speak to them remotely.
Siminoff asked for $700,000 in exchange for 10% equity. The Sharks liked the technology but had reservations.
Lori Greiner questioned uniqueness, Mark Cuban doubted the growth trajectory, Robert Herjavec worried about hacking risk.
Kevin O’Leary made an offer: $700,000 with a 10% royalty (dropping to 7% after repayment) + 5% equity. Siminoff countered but then declined, walking away without a deal.
DoorBot Product Price on the Show
At the time of the pitch, Siminoff mentioned about $1 million in sales within nine months. The retail price then was around $199; cost of goods about $81.
Did Ring Get a Deal on Shark Tank?
No — the founder did not accept any deal from the Sharks. The only offer was from Kevin O’Leary, which was rejected, and thus the company left without Shark funding.
What Happened to DoorBot After Shark Tank
Although no deal was made, the Shark Tank appearance drove exposure and new sales. The company quickly expanded its product line, rebranded to Ring in 2014, and brought on investors like Richard Branson.
Before the Amazon acquisition, Ring raised over $200 million in funding. In 2018, Amazon acquired Ring for around $1 billion. On the flip side, Ring has faced controversies: privacy issues, partnership with law enforcement, data-sharing concerns.

Privacy critiques have grown. The company has acknowledged providing user footage without consent in some cases. With its expanded scale under Amazon, balancing growth with regulatory scrutiny is a key challenge.
How Is DoorBot Doing Today?
Ring remains active — still selling its video doorbells, cameras and ecosystem accessories. In April 2025, founder Jamie Siminoff returned to Amazon in a leadership role for Ring/Blink in an executive role as Vice President.
While Amazon does not break out Ring-specific revenue publicly, the range of product offerings and scale suggest solid performance. Grips Intelligence estimated Ring’s annual revenue for 2024 reached $420.9m.
