Highlighting the strategic significance of the acquisition, Alexander Lavin, CEO of Pasteur Labs, stated: “This acquisition represents a natural evolution of our mission to bridge the gap between breakthrough simulation-based R&D and real-world impact. FOSAI’s deep expertise in dual-use software systems integration, combined with their proven ability to deliver mission-critical solutions, gives us the pathway to deploy our Simulation Intelligence Platform where it can create the most value: in domains that demand both cutting-edge innovation and unwavering reliability.”
Pasteur Labs’ Simulation Intelligence Platform already empowers human-machine teams to rapidly explore vast spaces of industrial R&D hypotheses, spanning industries such as aerospace, automotive, nuclear energy, and data centers. With FOSAI’s systems architecture knowledge, Pasteur now seeks to solve a pressing challenge integrating next-generation AI-native engineering seamlessly into legacy operational systems.
Gregory Falco, CEO of FOSAI, emphasized the long-term impact of this collaboration: “The future of autonomous systems in sectors like aerospace and defense depends on our ability to model multi-scale phenomena and their cause-effect mechanisms with unprecedented accuracy and speed. Pasteur Labs’ approach to combining AI with physics simulation creates exactly the kind of foundation our most demanding applications require. Our experience with dual-use customers suggests this is the de facto standard platform for AI-driven simulation they’re looking for.”
