phagos

Phagos is a Paris biotechnology company founded in 2021 by Alexandros Pantalis and Adèle James that develops AI-enhanced bacteriophage therapies for bacterial disease, with an initial focus on animal health where antibiotic resistance constrains livestock productivity. Its patented AI analyses phage and bacterial genomes to predict interactions and design adaptable, personalised phage treatments; the company has obtained authorisation to market personalised phage-based veterinary medicines. In October 2025 Phagos raised a €25 million Series A co-led by CapAgro, Hoxton Ventures, CapHorn and Demeter, with Acurio Ventures, Citizen Capital, Entrepreneurs First, Founders Capital and Station F participating, to scale veterinary deployment, advance the AI platform and expand the team toward broader markets including a longer-term path to human health.
