ZaiNar just raised $100 million at a valuation above $1 billion. After nine years in stealth, ZaiNar is entering the arena with a tight thesis: wireless networks can become the sensing layer for Physical AI.
The constraint in real world autonomy has never been model quality alone but the absence of continuous, precise, shared location data. Agents can plan routes and generate actions, but they lack a synchronized view of where everything is, especially indoors or in dense environments.
ZaiNar uses the radio signals already emitted by 5G and WiFi infrastructure and synchronizes them at the sub nanosecond level. Radio waves move roughly 30 centimeters per nanosecond. Compress timing error below that and you get sub meter positioning accuracy, without satellites, camera grids, or custom beacon hardware.
That turns existing carrier and enterprise networks into a distributed sensing platform. Devices offload location processing to the network itself. Coordination improves. Battery and edge compute demands fall. The physical world starts to look queryable.
The company reports over $450 million in contracts and memoranda of understanding across healthcare, construction, smart city, and industrial deployments. It has filed more than 100 patents, with 90 issued, around phase based time synchronization and network computed positioning.
