Our co-founder Sophie spent six months in Asia at the end of 2017 – and by chance discovered the "Uterus Warmer" in a store. Since she herself suffered from severe period pain, especially since she stopped using hormonal contraception, she immediately grabbed it. Impressed by its effectiveness, she bought several packs – for herself and her friends.

Back home, Sophie told her partner and now co-founder Patrick about her discovery. As supplies soon ran out, the question arose: Why not organize more supplies—and perhaps make this help available to other women in Switzerland?

It quickly became apparent that many women wanted a little helper like Tummzy – but one that was modern and stylish. So Sophie and Patrick began searching for a suitable manufacturer.

After numerous failed attempts, dubious offers, and what felt like a thousand emails, they finally found their dream producer.

Now it was time for the details – the packaging. Together with their good friend Laura, Sophie and Patrick developed the corporate design, the packaging, and the layout of the patch. After many hours of work and intensive discussions, the result finally met their high standards.

In spring 2019, Sophie and Patrick traveled to China to gain first-hand experience. They toured the factory, spoke with the employees, shared their vision, and laid the foundation for a long-term partnership.

Back in Switzerland, final adjustments were made – and production started in September 2019.

Exactly on New Year's Day 2020, Sophie and Patrick held the first finished products in their hands – an unforgettable moment!

Since then, the Tummzy Uterus Warmer has been available and accompanies women through their periods – with strengthening warmth. We are infinitely grateful for your support. 💜

In 2021 and 2022, Tummzy grew steadily – not only through enthusiastic customers, but also through increasing media attention. Numerous magazines, online portals, and lifestyle platforms reported on our mission to remove the taboo from menstruation and empower women.

In 2023, we reached a new milestone with Tummzy: Over 14,000 customers already trust the Uterus Warmer. Tummzy is also available in almost 350 pharmacies and drugstores, as well as from select gynecologists throughout Switzerland – an important step toward providing even more women with easy access to warmth and well-being.

In February 2024, another significant step followed: the collaboration with Steinberg Pharma . This enabled distribution to be professionalized and expanded – with the goal of making Tummzy even more widely available and continuing the success story. Tummzy - Uterus Warmer is now available in over 650 pharmacies and drugstores throughout Switzerland.

In the summer of 2025, the Tummzy website was completely redesigned. With a fresh design, clear structure, and modern user experience, we want to better inform, inspire, and support our community—while continuing to break the taboo surrounding menstruation.
