Imagine waking up in the middle of the night, drenched in sweat from a sudden hot flush. This is a daily reality for many women going through menopause. Enter Coolzen, a smart wearable device designed to detect and alleviate hot flushes within 45 seconds. Developed by the company Unpause, Coolzen aims to provide instant relief and improve the quality of life for menopausal women.
Coolzen made its television debut on Dragons’ Den Season 22, Episode 8, which aired on February 27, 2025. Founder Nitya Dintakurti pitched the innovative product but left without securing investment.
The Dragons were concerned about the lack of clinical trials. Despite this, the product garnered significant public interest and sold out shortly after the episode aired.
What is Coolzen’s Net Worth?
As of April 9, 2025, Unpause has not publicly disclosed an official net worth. However, the immediate sell-out of Coolzen following its Dragons’ Den appearance shows strong consumer demand. This enthusiasm suggests that the company holds substantial potential value in the growing femtech market. Exact financial figures remain undisclosed at this stage.
How Coolzen Started
Coolzen was developed by Ru Medical Ltd, a startup focusing on women’s health solutions. The idea came from a personal experience. Founder Nitya Dintakurti watched her mother struggle with surgical menopause. This motivated her to create a device offering immediate relief from hot flushes.
Unpause collaborated with institutions like King’s College London to develop Coolzen. The goal was to bring innovative tech to an overlooked area of women’s health.
Journey on Dragons’ Den
During her pitch on Dragons’ Den, Nitya Dintakurti sought £100,000 in exchange for 2.5% equity in Unpause. She demonstrated Coolzen’s ability to detect hot flushes and provide rapid cooling relief.
The Dragons were interested in the concept but raised concerns about the lack of clinical validation.
For medical devices, trials are essential. As a result, no investment was secured during the show.
What Happened After Dragons’ Den?
Despite not receiving funding from the Dragons, Coolzen experienced a surge in popularity.
After the show, the product sold out quickly.
Unpause’s website began offering restock alerts to manage ongoing demand. This interest proves there is a strong market need for effective menopause solutions.
As of early April 2025, there have been no major updates. No announcements about new partnerships, funding rounds, or business expansion have been made.
Revenue Streams and Business Model
Unpause sells Coolzen directly to customers through its official website. This direct-to-consumer approach is their primary sales channel.
The company offers both one-time purchases and a subscription model. Subscribers receive monthly shipments of CoolTac adhesive strips and access to the Unpause app.
There are no confirmed retail partnerships or international deals yet. However, the positive consumer response points toward future growth opportunities.
Challenges and Success Factors
The main challenge facing Unpause is the lack of clinical trials. This was a critical concern for the Dragons and could slow down growth in healthcare or retail markets.
Still, the product’s success after the show shows strong interest from customers. This is a major win for a startup in such a sensitive space.
Coolzen’s strengths lie in its personal story, innovative tech, and focus on a real, widespread health issue.
These factors, along with industry trends, are boosting its early success.
Conclusion
Coolzen’s Dragons’ Den appearance revealed both its promise and its hurdles. The device didn’t win investment, but it clearly won attention.
With growing consumer demand and momentum in femtech, the future looks bright for Unpause.
For now, we’ll be watching to see how they grow, adapt, and possibly attract new funding.
