Precise, private, AI-native location for every device.
Consumer GPS chips have barely improved in twenty years. Zephr moves the positioning engine off the chip and into software — delivering sub-meter accuracy and full 6DoF orientation on ordinary Android hardware.
Paired with AI-native place data and on-device LLMs, Zephr gives any application a complete understanding of where it is and what surrounds it — without specialized hardware, without data leaving the device.
We've conducted advanced research in government and commercial navigation — enhancing warfighter situational awareness, improving rideshare accuracy, and advancing pedestrian safety in autonomous systems.
