Who We Are

Fidelis Machines builds AI and autonomous systems for defense, critical infrastructure, and industrial security — a small, focused engineering team working at the intersection of signals intelligence, machine learning, and autonomous robotics.

Every solution we build is validated on our 200-acre proving ground in Central Virginia. We integrate our autonomy stacks on field-proven, NDAA-compliant autonomous ground vehicle platforms, bringing software and hardware together as a complete operational solution.

Fidelis Machines operates under Fidelis Farm & Technologies LLC, a Service-Disabled Veteran-Owned Small Business (SDVOB).
