Anello Photonics Raises Additional $25M in Series B-2 Funding

The company plans to use the funds to accelerate its growth and expand the adoption of reliable navigation solutions for autonomous systems operating without GPS across land, air, and sea.

Global Navigation Satellite Systems (GNSS), such as GPS, are essential for modern infrastructure in both defense and commercial sectors across land, air, and sea. However, they are becoming increasingly vulnerable to issues such as jamming and spoofing, which can cause major disruptions, cost billions worldwide, and affect everyday activities and critical systems.

ANELLO Photonics’s technology uses silicon photonics to provide a cost effective alternative to traditional navigation systems, offering accurate positioning without relying on external signals like GPS. Its SiPhOG™ platform delivers high performance optical gyroscope capabilities in a compact, scalable design, helping autonomous systems operate reliably on land, in the air and at sea even in challenging GPS denied environments.

As autonomous systems become more common, and electronic warfare advances the ability to navigate without GPS is becoming essential. ANELLO Photonics is leading this shift with its compact, chip based technology that combines high performance with efficiency to deliver reliable navigation at scale.

"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.

"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."
