Juxta is a technology company based in San Francisco that has developed the Universal Positioning System (UPS), a hardware-free, real-time location tracking solution designed to work anywhere on the planet. Juxta's system enables instant mapping and positioning with sub-meter accuracy indoors and approximately three meters outdoors, leveraging synthetic fingerprinting and advanced machine learning models.
The UPS stands out by not requiring any new hardware or beacons—using only the sensors already present in mobile devices, robots, or other machinery. The platform is offline-capable, resistant to jamming, encrypted, and can be deployed remotely. This allows physical spaces to be transformed into intelligent, trackable environments in minutes, rather than the months typically required by other solutions. Its flexibility and security make it suitable for use in sectors where traditional GPS or tracking solutions may fall short.
Juxta's technology is applicable across a range of industries, including defense, logistics, robotics, and healthcare, where accurate and reliable positioning is critical. By removing the need for satellite connectivity or specialized hardware, Juxta addresses the longstanding challenges of indoor positioning and resilient location tracking.
How Was Juxta Started?
Juxta was founded by John Ferrara, who serves as CEO, and is part of Y Combinator's S25 batch. The company's mission is to provide a GPS alternative that works indoors, offline, and independently of satellites or external beacons. This vision is supported by a small, technically-focused team, including Duru Huseyni.
What Makes Juxta's UPS Different?
- Hardware-free: No new sensors or beacons required; uses existing device sensors.
- Offline-capable and unjammable: Works without internet or satellite connection, and is resistant to interference.
- High-accuracy: Sub-meter positioning indoors, ~3 meters outdoors.
- Rapid deployment: Can set up tracking environments in minutes.
- Encrypted and secure: Designed for sensitive and mission-critical applications.
