ANELLO Photonics Raises $25 Million to Scale GPS-Denied Navigation Platform

New updates have been reported about ANELLO Photonics.

ANELLO Photonics has raised an additional $25 million in an oversubscribed Series B-2 round to accelerate production and deployment of its silicon-photonics-based inertial navigation systems for GPS-denied environments. The financing was led by MESH, with participation from new investor Washington Harbour Partners and existing backers including Lockheed Martin Ventures and several venture firms, underscoring growing institutional confidence in ANELLO’s technology and defense and dual-use market positioning.

The new capital is earmarked to scale manufacturing of ANELLO’s SiPhOG platform, a chip-scale optical gyroscope that targets fiber-optic performance at lower cost and size, weight, power, and cost (SWaP-C) levels. Management expects the funding to support broader deployment across land, air, and sea platforms that require resilient navigation in contested or jammed GNSS environments, where disruptions are already estimated to cost billions globally. CEO and co-founder Dr. Mario Paniccia said the raise will enable ANELLO to ramp production, accelerate product innovation, and deliver more systems to customers facing increasingly sophisticated electronic warfare threats.

Investors highlight ANELLO’s combination of differentiated silicon photonics technology, manufacturability, and demonstrated traction in mission-critical defense and commercial applications as a foundation for becoming core infrastructure for next-generation autonomous systems. ANELLO’s integrated photonic system-on-chip architecture, backed by more than 80 issued or pending patents and an AI-based sensor fusion engine, positions the company to compete directly with legacy fiber gyros while offering a more scalable cost structure. As autonomy expands and reliance on GPS faces mounting security and reliability concerns, ANELLO’s strategy centers on establishing its SiPhOG-based navigation stack as a standard for resilient positioning, with this latest funding round providing additional runway for growth, customer acquisition, and potential defense and industrial partnerships.
