London-based Daye, a female-founded gynaecology health startup, announced that it has been granted a new patent covering both the design and manufacturing of its proprietary Organic Diagnostic & Menstrual Tampon.
According to Valentina Milanova, the founder of Daye, the newly patented product works better than the most absorbent synthetic fibre tampons and uses only organic, plastic-free materials.
The product features a protective sleeve that prevents fibre shedding, a dual-surface structure for faster, even fluid absorption, and a cupped tip that expands uniformly to reduce leaks and discomfort.
With the ability to incorporate therapeutic coatings and a scalable, precise manufacturing process, this innovation sets a new benchmark in sustainable, high-performance gynaecological products.
“This is a major win for performance, sustainability, and patient experience — especially since absorbency is still one of the top reasons people hesitate to switch to organic,” says Milanova in a LinkedIn post. “And in the context of diagnostics, with our Diagnostic Tampon, we’re proud to bring sustainability to a space long dominated by petroleum-derived plastics.”
Raised £11K
The announcement comes three months after raising £11,114 through the Bright Friday campaign in just 10 days.
The company used the funds to focus on critical and often underfunded issues in women’s health.
These projects include the development of a new non-hormonal, non-surgical medication for endometriosis pain, the use of menstrual fluid as a diagnostic tool for heavy periods, and investigations into the causes of heavy bleeding related to endometriosis.
Additionally, ongoing research is being conducted into gynaecological cancers, including ovarian and endometrial cancer.
Daye partners with Wellbeing of Women
Daye is focused on improving gynaecological health research and closing the gender health gap. They aim to create better products for women and those assigned female at birth (AFAB), while also advocating for improved care and research.
They have partnered with Wellbeing of Women, a charity that has been leading in women’s health research.
Wellbeing of Women has funded critical research on issues like endometriosis, heavy periods, and gynaecological cancers, which impact millions but often do not receive adequate attention or funding.
Over 40 years, Wellbeing of Women has helped fund research that established the use of ultrasound in pregnancy care. This advancement has allowed for the early detection of conditions such as spina bifida and has improved monitoring for high-risk pregnancies.
They were also involved in the research that identified the link between HPV infection and cervical cancer, which contributed to the development of a national screening program in the UK and the HPV vaccine, resulting in a significant decrease in cervical cancer rates.
