ANELLO Photonics has secured $25 million in Series B-2 financing round to accelerate production of its silicon-photonics-based inertial navigation systems for GPS-denied and contested environments.
The round was led by MESH, an electronics-focused venture capital firm, with participation from new investor Washington Harbour Partners alongside existing backers Lockheed Martin Ventures, Catapult Ventures, New Legacy Ventures, One Madison Group, IronGate Capital, and Mana Ventures.
The Santa Clara, California company develops the SiPhOG — Silicon Photonics Optical Gyroscope — a chip-scale optical gyroscope designed to deliver fiber-optic-class inertial performance in a compact, lower-cost form factor using standard semiconductor manufacturing processes. The platform targets autonomous systems operating across land, air, and maritime domains where GNSS signals are degraded or unavailable.
“Reliable navigation is fundamental to autonomy, safety, and mission assurance,” 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.”
The Series B-2 follows a January 2026 Army APFIT award of $20 million to accelerate procurement and fielding of ANELLO’s GPS-denied navigation technology. The company’s intellectual property portfolio now spans more than 80 issued or pending patents, alongside an AI-based sensor fusion engine.
