What ZaiNar does

ZaiNar is a private Belmont, California-headquartered deep-tech company founded in 2017 that builds a sub-nanosecond time synchronization platform transforming existing wireless infrastructure — 5G, WiFi, private cellular, and IoT networks — into spatial sensing systems for Physical AI applications. The platform operates entirely on the network side, using the Sounding Reference Signal (SRS) that connected devices already transmit 100-500 times per second, delivering sub-10cm positioning accuracy at ranges up to 1.5km with 100-500 position updates per second, without adding hardware, software, or compute to the tracked device.

The company's product is a single unified platform rather than a suite of point products. It is sold via direct enterprise sales to two primary buyer types: (a) telecom carriers and network operators seeking to monetize existing 5G infrastructure through location-based services, with an estimated $1-2B per-city-per-carrier revenue opportunity; and (b) large enterprise operators in healthcare (equipment and staff tracking, estimated to eliminate 20-30% of staff search time), construction (live equipment tracking, dynamic safety zones, progress monitoring), autonomous operations, industrial environments, and smart cities. Revenue is generated through recurring subscription contracts and memoranda of understanding, with over $500M in such agreements disclosed across multiple continents as of April 2026.

ZaiNar emerged from nine years of stealth in February 2026 with a $100M funding round at a $1B+ valuation, backed by Steve Jurvetson, Jerry Yang, Tom Gruber, Jaan Tallinn, Nicholas Pritzker, and advised by Andreas Weigend (former Amazon Chief Scientist) and Nishant Batra (former Nokia CSTO). The company has filed 100+ patents with 90-95+ issued and zero rejections. By April 2026 it had opened its first APAC hub in Tokyo, selected for the Tokyo Metropolitan Government's GX-Related Foreign Company Market Entry Support Program. Forward applications identified in public communications include data center throughput optimization and GPS-resilient positioning for defense.

Revenue model

1. Network Location Services to Carriers: ZaiNar enables telecom carriers to offer location-based analytics and advertising as products in their own right, across the operator's footprint, sourced from infrastructure already owned. Estimated addressable revenue of $1 to $2 billion per major city per carrier based on early estimates from carrier conversations. Carriers and enterprises gain direct access to sub-10cm location data on every phone, robot, car, or IoT device on their networks.
2. Enterprise Location-as-a-Service: Provides real-time spatial awareness as a service to enterprise customers (healthcare, construction, logistics, smart city operators) enabling operational efficiency improvements such as equipment utilization, staff time savings, and asset tracking. Contracts and memoranda of understanding already secured at over $500 million across multiple continents.
3. Data Center Throughput Optimization: Sub-nanosecond synchronization applied to data center operations to shrink packet buffer gaps, potentially doubling throughput without additional bandwidth or power — a future monetization stream.

Core offering

ZaiNar develops and sells a sub-nanosecond time synchronization platform, marketed as the Physical AI Platform, that transforms existing 5G, WiFi, private cellular, and IoT wireless networks into spatial sensing systems. The platform performs positioning entirely on the network side using the Sounding Reference Signal (SRS) that devices already transmit 100-500 times per second, achieving sub-10cm accuracy across ranges up to 1.5km without satellites, cameras, dedicated hardware, or device-side software or OEM cooperation.

Product overview

ZaiNar offers a single unified Physical AI platform that turns existing wireless infrastructure into spatial sensing systems. The platform consists of the core positioning technology (Physical AI Platform) that achieves sub-nanosecond time synchronization across 5G and WiFi networks to deliver sub-10cm positioning accuracy. The platform operates entirely on the network side, requiring no software on devices being located. It is protocol-agnostic and works across 5G, WiFi, private cellular networks, and future wireless standards. No separate modules or add-on products are named - the single platform offering provides the sensing capability as a network function for carriers and enterprises.

Direct peers

• NextNav: NextNav operates a terrestrial 'pseudolite' positioning network intended to complement or replace GPS, targeting indoor and urban positioning. It is the closest publicly analogous peer because it also sells 3D location services sourced from terrestrial wireless infrastructure rather than satellites.
• Locata: Locata provides a terrestrial positioning alternative to GPS using time-synchronized 'LocataLite' transceivers. Highly comparable in approach — leveraging sub-nanosecond time synchronization across terrestrial transmitters — though focused on dedicated hardware rather than existing 5G/WiFi.
• Polaris Wireless: Polaris Wireless delivers high-accuracy location services to telecom carriers using network-based techniques, including for E911/regulatory use cases. It shares ZaiNar's carrier-channel GTM and network-side architecture philosophy.
• u-blox: u-blox designs positioning and wireless modules and chips for GNSS, cellular, and short-range. While chip/device-focused rather than network-side, it is a comparable positioning-tech vendor serving IoT, automotive, and industrial customers.

Broad incumbents

• Qualcomm: Qualcomm integrates positioning into its 5G modems and Snapdragon chipsets, including 3GPP-defined NR Positioning. Competes in the same accuracy-vs-network-location battle but from the device/chip side rather than the network-side.
• Ericsson: Ericsson supplies RAN equipment with built-in positioning support and works with carriers on 5G NR Positioning features. As one of the dominant RAN vendors ZaiNar must interoperate with, it could absorb the same functionality into its own stack.
• Nokia: Nokia's Networks business includes carrier-grade positioning features for 5G; the company's former CSTO (Nishant Batra) is now a ZaiNar advisor. Nokia competes as a RAN incumbent and potential integration partner.
• HERE Technologies: HERE provides location data, mapping, and location-based services to enterprises and automotive OEMs. Compares as a broader location-services incumbent with whom carriers and enterprises may bundle versus ZaiNar's higher-accuracy network-side offering.
• Trimble: Trimble provides high-accuracy GNSS and positioning solutions across construction, agriculture, geospatial, and logistics. Comparable in targeting construction/industrial use cases that ZaiNar explicitly addresses, though primarily GNSS-based.
• Broadcom: Broadcom supplies networking, timing, and synchronization semiconductors (including PTP/SyncE silicon) and could integrate sub-nanosecond timing features into telecom silicon that overlap with ZaiNar's network-side solution.
