Participated · Series A · Jan 2026
Aviwell develops microbiome-based animal nutrition products that use native bacterial ecologies to enhance health, performance, and robustness in livestock. Powered by its proprietary Aneto AI-driven discovery platform, the company designs targeted microbial communities with clearly defined modes of action. Its initial commercial focus is on poultry and aquaculture, two sectors facing mounting sustainability and antibiotic-resistance challenges. To date, Aviwell has secured €11 million in Series A funding to accelerate R&D, validate and scale its microbial ecologies, and broaden access to its Aneto platform as a service. The fresh capital will also support deeper commercial engagement with partners and customers. Aviwell operates from headquarters in Toulouse, France, and maintains an additional office in Lowell, Massachusetts.
