ANELLO Photonics, a developer of silicon photonics–based inertial navigation systems for GPS-denied environments, announced a $25 million Series B-2 extension round led by MESH, with participation from Washington Harbour Partners and existing investors including Lockheed Martin Ventures.
The oversubscribed financing will support global expansion and accelerate deployment of resilient navigation solutions for autonomous systems across land, air, and sea.
Technology and Market Need
Global Navigation Satellite Systems, including GPS, remain critical infrastructure but face increasing risks from jamming and spoofing. ANELLO addresses these vulnerabilities with silicon photonics – based inertial navigation technology that delivers high-precision positioning without reliance on external signals.
The company’s SiPhOG™ platform provides fiber-optic–class performance in a compact, scalable form factor, enabling reliable navigation in contested and GPS-denied environments.
“MESH is excited to invest in ANELLO because they have built a truly differentiated, defensible navigation platform for a world where GPS cannot be assumed. By delivering fiber-gyro class performance in a chip-scale, manufacturable form factor - and pairing it with real traction in mission-critical defense and dual-use markets - ANELLO has the potential to become foundational infrastructure for the next generation of autonomous systems. We believe this is a rare combination of breakthrough technology, execution, and timing,” said Tony Fai, Partner at MESH.
Growth and Deployment
The new funding will enable scaling of production, continued product development, and broader adoption across industries requiring secure and precise navigation capabilities.
“Reliable navigation is fundamental to autonomy, safety, and mission assurance and we are excited to have MESH and Washington Harbour Partners as new investors in ANELLO,” said Dr. Mario Paniccia, Co-Founder and CEO of ANELLO Photonics. “This additional $25 million in funding will enable us to scale production, accelerate innovation, and deliver resilient navigation capabilities to meet the rising global demand. In addition, it will allow us to deliver more products to more customers operating in increasingly contested and GPS-denied environments.”
Industry Outlook
As autonomous systems expand and electronic warfare risks increase, navigation without GPS is becoming essential. ANELLO positions its chip-scale photonics platform as a scalable solution for next-generation resilient navigation infrastructure.
