Daye

What Daye does

Daye (legal entity Anne's Day Ltd) is a London-based gynecological health company founded in 2017 that combines consumer period-care products with at-home diagnostic services for women and AFAB individuals. Its product platform is organized into three pillars: Vaginal Health (tampon-based microbiome screening, STI and HPV screening kits, ProViotics supplements, nurse consultations), Hormonal Health (at-home hormone testing covering thyroid, perimenopause, and fertility, plus the Period & Pelvic Pain Clinic), and Period Care (organic cotton and CBD-infused tampons, hemp pads, and bundles). Core technology includes a proprietary CBD tampon formulation clinically tested for safety (no TSS toxins, no irritation, no systemic toxicity) and ISO 13485/GMP-compliant manufacturing, with diagnostic samples processed by UKAS-accredited and CQC-registered laboratories.

The company operates a primarily DTC, product-led growth model via its e-commerce storefront (yourdaye.com) with localized versions across the UK, EU, and US, supplemented by subscription recurring deliveries (12-tampon plans from £6 with up to 20% multi-month discounts), a £5/20%-off referral programme, and a five-step ambassador programme. Distribution extends to premium retail (Liberty, Planet Organic, Oliver Bonas), corporate employee perks partnerships (Meta, Monzo), and a U.S. telehealth distribution agreement with Wisp. Daye is supported by EIC co-funding and publicly backs the NHS cervical cancer eradication goal by 2040, and is a member of the Women's Health Visibility Alliance coalition alongside Essity, Clue, Hertility, and Mooncup.

Total disclosed funding is approximately $17.1M across a 2019 seed led by Khosla Ventures ($5.5M, with Index Ventures and Kindred Capital) and a 2022 Series A led by Salica ($11.6M, with Cross-Border Impact Ventures, MMV Europe & Asia-Pacific, and Simplyhealth), plus a Google for Startups grant in 2018. The company is privately held, founder-led by Valentina Milanova, with Hannah Allen as Chief Medical Officer, and operates with a 11–50 person team. No revenue or ARR figures are disclosed in the source data.
