- Alloy
Led · Equity · Jun 2026
Alloy operates a telehealth platform that links women with physicians trained in menopause care, offering clinician community support and annual in-person training for its providers. The company emphasizes capital-efficient growth, claiming near-zero physician attrition and zero recruiting costs because clinicians join organically. Alloy reached profitability around its Series A in November 2024 and has since reinvested earnings into growth rather than hoarding cash. Its leadership, including co‑founders and co‑CEOs Anne Fulenwider and Monica Molenaar, positions the company as deliberately disciplined compared with better‑funded peers. The broader market context cited in reporting notes roughly 1.3 million U.S. women enter menopause each year and a global menopause market valued at about $17.8 billion in 2024. Alloy is pursuing a retention- and unit-economics-driven expansion rather than rapid, capital-intensive scaling.

It is led by CEO Siew-Veena Sahi and was founded in 2021. The company’s first product is a urine-based self-test for chlamydia and gonorrhea that delivers lab-quality results in less than 30 minutes. Testmate positions the device for use anywhere at any time and emphasizes diagnostic accuracy. The startup raised $6M in Seed funding to support development of the OTC STI self-test. Its team comprises experts in sexual health and diagnostics. Testmate Health is developing a rapid urine self-test that delivers at-home results in minutes for the four common sexually transmitted diseases and digitally connects users to healthcare professionals for consultation and prescription if needed. The company is finalizing its prototype, plans small-batch in-house manufacturing, and will enter pre-clinical studies at the Hopitaux Universitaires de Genève. Testmate recently closed a seed round (amount undisclosed) and received additional support from the Biopôle Start-up Fund. It will use the 90k Biopôle funds toward lab and office infrastructure, hiring commercial and regulatory consultants, and equipment to begin small-batch production of test kits.

Testmate Health is an award‑winning spin‑off of the University of Geneva building a rapid digital at‑home urine test for common STDs.

Its product aims to let customers skip clinic visits and avoid multi‑day waits by offering a simple, immediate self‑test. The start‑up closed an oversubscribed seed financing round totaling CHF1.6 million, with a first closing earlier in the spring and an extension to bring in additional investors. Proceeds will be used to accelerate product development and complete pre‑clinical studies of the device ahead of commercialisation. The financing also brings experienced advisers onto the governance team to support the next stages of development.
