Pasteur Labs Buys AI Startup FOSAI

Pasteur Labs, developer of simulation intelligence (SI) technologies and applications that natively integrate AI/ML and physics simulation, reports its acquisition of FOSAI, a provider of space systems and autonomy solutions for the aerospace and defense sectors.

 

The acquisition positions Pasteur Labs to bring its AI-driven simulation capabilities to more real-world applications, powered by FOSAI's experience in mission-critical deployments, Pasteur Labs reports.

FOSAI is a partner for US Space Force, DARPA, and various commercial aerospace companies and defense primes. The company's expertise centers on creating digital platforms for system integration, offering plug-and-play solutions and data services integration.

"This acquisition represents a natural evolution of our mission to bridge the gap between breakthrough simulation-based R&D and real-world impact," says Alexander Lavin, CEO of Pasteur Labs. "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 enables human-machine teams to explore exponentially larger spaces of industrial R&D hypotheses and solutions, in sectors from aerospace and automotive to nuclear energy and datacenters. Now with FOSAI's knowledge in systems architecture, Pasteur aims to address integrating next-generation AI-native digital engineering into legacy operational systems.

"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," says Gregory Falco, CEO of FOSAI. "Pasteur Labs' approach to combining AI with physics simulation creates exactly the kind of foundation our most demanding applications require."

FOSAI's work has historically focused on providing specialized technical capabilities for federal initiatives. While much of their work involves confidential applications due to the sensitive nature of defense and aerospace requirements, their publicly acknowledged projects demonstrate expertise in creating scalable platforms that can handle challenging integration scenarios.

The acquisition comes as Pasteur Labs prepares for a public launch of its platform later in 2025, with a lineup of data generation products and end-to-end physics-AI applications to follow. The company's international team includes industry veterans from NASA, Tesla, NVIDIA and Ansys.

"We're not just acquiring a company—we're gaining access to the practical wisdom that comes from successfully deploying advanced technologies in the most demanding environments," addesLavin. "This positions us to ensure that our simulation breakthroughs translate into real and reliable operational advantages."

The financial terms of the acquisition were not disclosed.
