Microbiome-mapping system developer raises £9.5m for expansion

Aviwell SAS , a company that uses artificial intelligence to select bacteria that may be used to enhance the health of farmed fish and poultry, has raised €11 million (£9.55m / US $13m) for finance the next stage of its development.

Toulouse-headquartered Aviwell has developed Aneto, an AI‑powered microbiome discovery platform built on decades of research by the company's co-founder, Professor Remy Burcelin.

Aneto maps and decodes the animal microbiome and is designed to identify native bacterial communities that can improve animal health and performance. These insights can be turned into practical microbial solutions for producers by creating tailored bacterial ecologies designed to enhance animal performance, immunity, and robustness.

Feed efficiency

Aviwell says that by combining advanced microbiota analysis with AI and machine‑learning‑driven discovery, it delivers measurable improvements in feed efficiency and immune function support while significantly lowering the cost and complexity of developing next‑generation animal nutrition solutions.

It will use its new capital, raised in a Series A investment round, to advance its poultry and aquaculture microbial ecologies from discovery through validation and scale‑up.

“Aviwell sits at the intersection of two powerful market forces: rising global demand for animal protein, and the accelerating consumer shift toward natural, sustainable, antibiotic‑free production systems,” the company’s president and chief executive, Mouli Ramani, said in a press release.

“With Aneto, we can translate microbiome complexity into practical, scalable solutions - helping livestock and aquaculture producers improve productivity while reducing their environmental footprint. With the support of our new investors, Aviwell will accelerate development in poultry and aquaculture and expand our platform and product pipeline.”

Hatch Blue

The financing round was led by Blue Revolution Fund (BRF), which invests globally in sustainable aquaculture, alternative seafood, and nutrition solutions, and is managed by aquaculture accelerator Hatch Blue.

BRF managing partner Georg Baunach said: “Aneto represents a new generation of microbiome innovation - one that captures the inherent complexity of biological systems. We believe this approach can unlock the next wave of solutions for poultry, aquaculture and livestock in general by delivering meaningful improvements in performance, resilience and environmental footprint.”

The other investors were Blast.Club, a private investment club that invested €125 million in 2025, and SWEN Capital Partners, which has €10 billion in assets under management and advisory.

Revolutionising agri-food

Anthony Bourbon, founder of Blast.Club, said: “We invested in Aviwell for one simple reason: they are revolutionising the agri‑food industry. Aviwell uses AI and life sciences to naturally boost animal growth, without hormones or antibiotics, simply by working on the microbiota.

“That's what we like: impact, innovation and a real long‑term vision. Feeding better, in a healthier, more sustainable way. Changing the rules of the game instead of playing by them.”

Julien Bourret, investment director at SWEN CP, said investing in the microbiome means investing in the future of health and a sustainable economy.

“For us, supporting Aviwell is about building a measurable, sustainable economic model - reducing chronic disease costs and creating responsible, long-term value,” added Bourret.
