Circadian Optics Net Worth 2025: Inside Their $750K Shark Tank Success Story
The story of Circadian Optics' current net worth seems unreal considering it began with a bold pitch on Shark Tank. The founder asked for $750,000 for just 10% equity, putting the company's value at $7.5 million. This light therapy lamp company stands as one of the show's most remarkable success stories.
The Sharks couldn't help but notice the impressive numbers Amber Leong brought to the table. Her company had already generated $4 million in sales and boasted a 70% profit margin. She also revealed the company's lifetime sales had reached $7.4 million at the time she appeared on the show.
Circadian Optics has grown substantially since their memorable Shark Tank appearance. The company's net worth has reached approximately $9 million with a steady 20% yearly growth rate. Some sources point to a possible $13 million valuation based on the company's estimated sales of $5.6 million for 2019.
Let's take a closer look at Circadian Optics' experience from a simple Shark Tank pitch to a thriving multimillion-dollar business. We'll explore their current valuation and see how this innovative light therapy company changed the market.
Circadian Optics Net Worth in 2025
Circadian Optics' current net worth stands at approximately $9 million in 2025. Some market analysts believe it could be worth closer to $7 million based on recent performance metrics. The company has changed from a promising startup into a major player in the light therapy market since its memorable Shark Tank appearance.
How much is Circadian Optics worth today?
The company makes approximately $4-5 million in annual revenue. This shows considerable growth from the $652,000 revenue during their Shark Tank appearance. Their profit margins remain strong at around 25%, which brings in about $1.3 million in profit each year.
Thrasio, a company that buys Amazon-based businesses, acquired Circadian Optics in 2021. The deal was worth $1 million, though they didn't reveal all terms publicly. This business decision has without doubt shaped the company's market position and growth potential.
Their success on Amazon shows in the numbers – over 6,140 reviews for their light therapy lamps. This proves both their market success and customer satisfaction. Their products have also earned more than $10,000 five-star reviews from customers of all types.
Growth since Shark Tank appearance
Circadian Optics has grown remarkably. Their numbers before Shark Tank were:
- Lifetime sales of $7.4 million
- Annual revenue of around $4 million
- Profit margins of 70% on products with an average sale price of $57.99
Mark Cuban and Lori Greiner's original investment was $750,000 for 20% equity, which valued the company at $3.75 million. Amber's first ask valued the company at $7.5 million, but they adjusted this significantly.
The business expanded beyond online sales to Walmart and Best Buy. Their retail presence and online growth have helped maintain a steady estimated annual growth rate of about 20%.
Estimated valuation based on sales and market presence
The light therapy market helps put Circadian Optics' valuation in perspective. The light therapy lamp market was worth about $10 billion in 2023. Experts project it will reach around $25 billion by 2030, showing a strong compound annual growth rate of 14%.
The Circadian Optics Light Therapy Lamp market revenue reached $100 million in 2024. Estimates suggest it will grow to $250 million by 2033, with a CAGR of 10.5%. People now understand light therapy benefits better, and more cases of Seasonal Affective Disorder, which affects about 5% of the U.S. population, drive this growth.
The company's market position looks promising. Remote work popularity and better awareness of circadian rhythm disorders create more need for light therapy solutions. About 70 million Americans struggle with sleep disorders, which puts Circadian Optics in a great position to serve this growing market.
Amber Leong's Experience to Entrepreneurship
Circadian Optics' impressive $9 million net worth tells the story of its founder Amber Leong. Her path from Malaysia to Minnesota—and eventually to Shark Tank—shows how personal challenges can lead to business breakthroughs.
Early life and move to the U.S.
Amber Leong grew up in Malaysia in a middle-class family with big dreams. Unlike many entrepreneurs who started their business in the United States, her story began thousands of miles away in a tropical climate where seasonal affective disorder wasn't part of her daily life.
Amber made a life-changing choice to study in America at age 20. Her parents believed in her dream so much that they took out their retirement savings of $20,000 to fund her education. Their sacrifice showed just how much faith they had in her future.
Minnesota's environment was completely different from her tropical upbringing. The harsh winters and short daylight hours later became the spark for her business idea. She landed a corporate job and started building her life in America after graduation, but adapting to the new environment proved tougher than she expected.
Health crisis and motivation to start Circadian Optics
Life took an unexpected turn when Amber faced a serious health crisis. Doctors diagnosed her with Toxic Shock Syndrome, a rare but dangerous bacterial infection at age 25. Her health got worse fast, and in the hospital, doctors gave her a 50-50 chance to live.
This close call changed everything. After getting better, Amber looked at health and well-being differently. She studied ways to optimize health, especially sleep quality and natural body rhythms.
The short, dark winter days in Minnesota led to symptoms of Seasonal Affective Disorder (SAD). Her research showed how light therapy could help circadian rhythms and overall wellness. The light therapy lamps available looked too clinical, had poor designs, and weren't practical for everyday use.
She saw an opportunity. People needed stylish, effective light therapy lamps they'd want to display in their homes and offices. That's how Circadian Optics was born.
Original challenges and product development
Building Circadian Optics came with its share of obstacles. Amber and her husband used their savings to start the company. They had no contacts in manufacturing or product design and learned everything from scratch.
They spent endless hours studying light therapy specifications, creating prototypes, and finding manufacturers who could bring their vision to life at reasonable costs. Their first designs focused on three things missing from existing products: good looks, usefulness, and affordable prices.
Their first product launch on Amazon showed promise, but growing brought new challenges. Managing inventory, handling customer service, and marketing costs stretched their budget thin.
Amber's dedication to creating beautiful, effective light therapy solutions pushed the company forward. By the time she pitched on Shark Tank, Circadian Optics had already achieved amazing sales. This proved that customers wanted well-designed health products.
The company's growth from Amber's health scare to a multimillion-dollar business shows how finding gaps in markets—mixed with personal drive—can create remarkable business success.
The Shark Tank Pitch Breakdown
Circadian Optics delivered an unforgettable Shark Tank pitch. The company showcased strong business metrics and struck an emotional chord with the Sharks. Their pitch valuation laid the groundwork that helped them reach their current estimated worth of $9 million.
Original ask and company valuation
Amber Leong stepped into the Tank with confidence. She asked for $750,000 for 10% equity in Circadian Optics, which put her company's value at $7.5 million. The Sharks raised their eyebrows at these ambitious numbers.
Her sales figures backed up this bold ask:
- Total revenue hit $7.4 million since launching in 2016
- Sales reached $4 million in 2018
- She expected $5.6 million in sales for 2019
- Products sold at $57.99 on average
- The company enjoyed 70% profit margins
The numbers spoke volumes. Amber earned $652,000 last year and expected $1.3 million this year, even with tariffs eating into profits.
Sharks' reactions and questions
Kevin O'Leary stayed true to his style with direct questions about investment returns. Amber explained her plans to scale up and use the money to boost inventory.
The mood shifted when Lori asked about Amber's background. She shared her story of growing up in Malaysia without basic amenities like indoor plumbing. Her parents emptied their retirement savings to fund her American college education. Her health struggles touched the Sharks deeply.
Mark Cuban couldn't hold back his emotions. "You represent to everybody in America… the American dream. It doesn't matter where you come from. If you put your mind to it, anything is possible."
Guest shark Rohan Oza admired Amber's journey and business acumen. He passed on making an offer because he felt he couldn't add enough value to her company.
Final deal with Mark Cuban and Lori Greiner
The negotiations heated up with two competing offers:
- Mark Cuban and Lori Greiner proposed $750,000 for 20% equity
- Kevin O'Leary and Barbara Corcoran came in with a similar offer
Cuban and Greiner sweetened their deal. They added a $50,000 gift for Amber's parents to honor their sacrifice.
Amber knew she should negotiate as any entrepreneur would. Yet gratitude won over strategy. "I'm here for Lori and Mark. You have a deal," she declared. She accepted double the equity she planned to give up.
The deal valued Circadian Optics at $3.75 million. Though lower than her initial ask, partnering with two powerhouse Sharks helped push the company toward its current valuation.
What Makes Circadian Optics Stand Out
Circadian Optics has built its $9 million net worth by creating unique product features that set them apart from traditional light therapy competitors. Their fresh take on light therapy has reshaped an industry that was full of clinical, uninspiring designs.
Design and usability of the lamps
The bold, modern esthetic turns Circadian Optics lamps into conversation pieces rather than medical devices. Amber Leong created these stylish alternatives because existing light therapy products looked too clinical and unappealing. The company pioneered LED therapy lamps that "work as great as they look" and serve as statement pieces for any desk or living space.
These lamps come with one-touch operation and three brightness settings that let users customize their therapy sessions. The LEDs last 50,000 hours. This accessible design helps most people feel benefits within just one week of regular use.
Health benefits and circadian rhythm regulation
The science behind Circadian Optics' soaring win tells a compelling story. Their lamps produce full-spectrum 5500K light that matches natural daylight without harmful UV rays. This light profile helps keep healthy 24-hour body cycles in check. Users feel more awake during the day and sleep better at night.
Early morning exposure to these lamps reduces melatonin levels, fights sleepiness, boosts alertness, and enhances performance. Clinical research shows that light therapy can substantially lower depression scores after just one hour of use.
Comparison with other light therapy products
Circadian Optics stands out with their 4-Year EasyReplace Policy. They replace lamps at no cost if anything goes wrong. Their Minnesota-based customer service team provides reliable support.
Tests against other light therapy products reveal Circadian Optics lamps' unique features. To cite an instance, the Lampu model's lux output increases over time, while competing products typically dim.
The company blends function with form beautifully. They've turned light therapy from a purely medical treatment into an available wellness tool. This approach supports their growing market position and adds to their impressive valuation.
Post-Shark Tank Growth and Business Updates
Circadian Optics' net worth reached approximately $7 million by 2025. A major ownership change altered the map of the company's growth after its memorable Shark Tank appearance.
Retail expansion and online sales
Circadian Optics expanded beyond direct-to-consumer channels after securing the Shark Tank investment. The brand made its way into Walmart stores, which helped Amber Leong achieve her vision of broader market reach.
Amazon sales remain exceptional, where their flagship product—the Lumos 2.0 Light Therapy Lamp—has earned over 6,000 ratings with an average of 4.6 out of 5 stars.
The company's trajectory took a new direction when Thrasio acquired it during 2020-2021. Thrasio specializes in buying successful Amazon businesses that generate $1 million to $100 million annually. The company changed its focus toward an Amazon-centric strategy, and by mid-2022, their website redirected to Amazon.
New product lines and innovations
Circadian Optics kept developing state-of-the-art products during this transition. Their lamp collection grew with diverse designs that offered different esthetics and functionality. Each lamp maintained the essential 10,000 lux brightness and full-spectrum 5500K light.
Market trends show manufacturers now add advanced features like smart technology integration. Users can control settings through mobile apps. These improvements create individual-specific experiences that address the growing need for personalized health solutions.
Media coverage and customer feedback
The company's lamps have collected more than 10,000 five-star reviews online. Major publications such as The Wall Street Journal, CNN, Inc., Architectural Digest, Bustle, Forbes, and Vogue have featured their products. Customers consistently report better mood, energy levels, and sleep quality.
A customer shared, "Working a 9 to 5 desk job indoors for many years now has had a most important effect on my health and happiness although I didn't realize the full extent of it until I started using this lamp". Another customer reported feeling "more energized and alert during the day".
Amber Leong left the company in December 2021. She took a break before joining General Mills to co-found their internal venture capital arm, G-Works Venture Studio.
Conclusion
Circadian Optics is a remarkable success story with a net worth of about $9 million in 2025, though some analysts point to figures closer to $7 million based on recent performance. The company's path from a bold Shark Tank pitch to a multimillion-dollar acquisition shows how creative thinking and personal passion can create extraordinary business outcomes.
The company grew rapidly after securing that $750,000 investment from Mark Cuban and Lori Greiner. Amber Leong's solution to her own seasonal health challenges became a brand with strong retail presence online and in major stores like Walmart and Best Buy.
The acquisition by Thrasio in 2021 was a major milestone that moved the company toward an Amazon-centric approach while keeping its core product breakthroughs.
Without doubt, Circadian Optics succeeded by filling a real market gap – stylish, effective light therapy lamps that people wanted to display in their homes. Their products struck a chord with consumers who suffered from seasonal affective disorder and sleep issues because of their sleek design, scientific backing, and genuine health benefits.
Their thousands of positive reviews and media features showcase both product quality and smart brand positioning.
Amber Leong's personal story adds another compelling layer – she moved from Malaysia to Minnesota, overcame a life-threatening illness, and ended up creating a business that solved her own health challenges. She has moved on to new ventures, but her effect on the light therapy industry lives on through the products she designed.
The light therapy market shows promising growth potential, with projections reaching $25 billion by 2030. Circadian Optics' strong position in this expanding market points to continued opportunities as people become more aware of circadian rhythm disorders and remote work grows more common.
Their success reminds us that great businesses often start by solving personal problems and can grow into multimillion-dollar enterprises that improve countless lives.
