Hidonix Pivots Into Defense With Navigation Tech

A Santa Monica spatial intelligence startup that once focused on helping museum visitors navigate centuries-old Italian architecture is now setting its sights on the U.S. defense sector, and the company says the pivot follows the technology, not the funding cycle.

Hidonix, founded in 2020 by Achille De Pasquale, built its core product around a problem that sounds almost quaint: how do you help visitors find their way through a 13th-century building when you can’t drill a single hole in the walls? The answer, De Pasquale discovered, was geomagnetic field mapping. By reading the unique magnetic signature of a structure, Hidonix’s platform could guide people through indoor spaces without any physical hardware installation.

That technology eventually became ION, short for Indoor Outdoor Navigation, now deployed in hospitals, museums, and convention centers. But the same capability that helps a visitor find the Renaissance wing now has applications that are considerably higher-stakes.

“The transition from the commercial side to the defense side was much longer than just taking advantage of the momentum right now,” De Pasquale said.

That momentum is real, though. Los Angeles tech companies pulled in $8.71 billion in venture capital in 2025, according to PitchBook, and more than half of that total flowed to aerospace and defense firms. With global conflicts accelerating demand for new defense contracting opportunities with the U.S. Department of War, dozens of L.A.-area companies are competing for a piece of that market.

Hidonix combines AI, its proprietary geomagnetic engine, and in-house hardware and software engineering into a platform built around spatial intelligence, the ability to visualize and track activity across a physical space in real time. The company found an intermediate step between museum navigation and defense applications when school districts came calling.

The result was SafeSchool, a platform designed for campus security. The system can track students who wander from designated areas, flag unfamiliar individuals on campus grounds, and coordinate evacuation routes during emergencies including active shooter incidents. It’s the kind of application that sits squarely at the intersection of the mundane and the critical.

“There was a transition period whereby we realized that these technologies that we could use for the schools could be actually applied to other sensitive targets,” said Paolo Casarella, Hidonix’s chief financial officer.

The company is not alone in recognizing how everyday spatial tracking tools can scale toward high-risk environments. Westlake Village-based Occuspace uses similar spatial intelligence technology to help college students check library occupancy before making the trip across campus. The gap between that use case and a battlefield situational awareness application is wide, but the underlying technology logic is not entirely different.

De Pasquale spent most of his career building software for theme parks and video game environments, including virtual reality applications, before founding Hidonix. His fixation on museums came from growing up in Italy, where preserving historic structures meant that interactive and self-guided visitor technology was largely locked out. Strict regulations prohibited any physical modifications to buildings housing Roman ruins or Venetian landmarks. That constraint became the founding design problem.

The defense push puts Hidonix inside a crowded but well-funded Los Angeles ecosystem. The region has spent years building aerospace and defense credibility through companies ranging from established primes to venture-backed startups, and the current funding climate rewards firms that can move between commercial and government contracting. Hidonix enters that competition with a platform already tested in real-world, high-sensitivity environments.

Whether hospitals and school campuses translate cleanly into proof-of-concept for defense procurement offices is the practical question the company now faces. Defense contracts carry long sales cycles, stringent security requirements, and procurement processes that can outlast a startup’s runway several times over.

What Hidonix has going for it is a product that didn’t originate as a defense pitch. ION was built to solve a real commercial problem, then found its way toward security applications through actual deployment. That trajectory tends to produce more credible technology than tools engineered from scratch around a government contract wish list.

The company remains based in Santa Monica, outside the Burbank and El Segundo corridors where much of L.A.’s defense-adjacent tech work concentrates. For now, that’s a geography story worth watching as the company scales.
