What Bio-Gate does

Bio-Gate AG is a Nuremberg-based German health technology company founded in 2000, listed on the German stock exchange (ISIN DE000BGAG981), that develops and commercializes silver-based antimicrobial and antiviral technologies for use across medical, cosmetic, veterinary, and industrial applications. Its two proprietary platforms are MicroSilver BG™, a highly pure, microporous elemental silver additive that can be incorporated into materials and formulations, and HyProtect™, an ultrathin (<200 nm) plasma coating combining pure silver and polysiloxane designed to protect medical implant surfaces against bacterial colonization, including multi-resistant organisms. Manufacturing is conducted in Bremen under DIN EN ISO 13485:2016 and DIN EN ISO 9001:2015, and the MicroSilver BG ingredient carries ECOCERT, COSMOS, and NPA natural product certifications.

The company monetizes through three channels: (1) B2B technology licensing and coating services to medical device manufacturers (notably orthopedic and trauma implant partners, with an FDA-track trauma LOI and a CE-track hip revision RCT of 200+ patients expected to read out in 2027); (2) sale of proprietary consumer products spanning derma cosmetics, wound care, and animal care (including the Silver Honey® line with W.F. Young in North America and horse care SKUs); and (3) accredited microbiological laboratory services through its wholly owned subsidiary QualityLabs BT GmbH, whose CERTIKA methods are recognized by European notified bodies and stored as FDA master files. A veterinary-exclusive joint venture, VetInnovations GmbH, is co-owned with LABOKLIN.

Distribution is hybrid: direct enterprise field sales to global medical device companies combined with multi-channel retail and e-commerce distribution (PetSmart, Petco, Walmart, Tractor Supply, Amazon, Chewy) for animal care, plus pharmacy and drugstore channels for derma cosmetics. The company operates representative offices in Bolton, Ontario (RFH BioTek Inc.) and Guangzhou (WunderTek) to support North American and Chinese business development. FY2025 revenue was 7.4M EUR (+4.9% YoY), with the veterinary segment up 48% and EBITDA loss narrowing 31.3% to -896 TEUR as the company approaches operational break-even.
