Arsenale is building a neo-industrial biomanufacturing company – one that integrates modular infrastructure, advanced sensing, and AI-enabled design to radically transform how biology is deployed at scale. As Chief Operating Officer, Arnaud Legris is connecting the dots across a complex system, with an evolving role as the company grows.

The Bioyard is our platform for industrial-scale precision fermentation. Traditional biomanufacturing sites are often built around bio-pharma and around legacy infrastructure, which can be rigid, costly, and difficult to optimize. At Arsenale, we wanted to take a different approach.

Scaling precision fermentation isn’t just about engineering microbes—it’s about building a biomanufacturing ecosystem that works at scale.
