ZaiNar has officially emerged from nine years of stealth with more than $100 million in investment and a valuation exceeding $1 billion, according to its February 19, 2026 press release. The Belmont, California–based company introduced a breakthrough platform that transforms existing wireless networks into a real-time sensing system for Physical AI. By leveraging already deployed 5G and WiFi infrastructure, ZaiNar enables continuous, sub-meter positioning without satellites, cameras, or additional device power. This funding milestone positions the company as a foundational infrastructure layer for intelligent machines operating in the real world. The announcement marks one of the most significant Physical AI infrastructure developments of 2026.
At the core of ZaiNar’s innovation is sub-nanosecond time synchronization across wireless networks. Radio waves travel approximately 30 centimeters per nanosecond, meaning synchronization at the sub-nanosecond level directly enables sub-meter location accuracy. The company states its system can time-synchronize signals thousands of times more accurately than conventional network timing methods. This precision allows connected devices to continuously understand their position relative to other objects in real time. The technology works indoors, outdoors, through walls, and around corners, addressing limitations of traditional GPS and camera-based systems.
The $100M+ investment round includes backing from prominent technology leaders and venture investors such as Steve Jurvetson, Jerry Yang, Tom Gruber, Jaan Tallinn, and Nicholas Pritzker. Their involvement signals strong confidence in ZaiNar’s approach to wireless sensing and spatial intelligence infrastructure. ZaiNar was founded in 2017 and has spent nearly a decade developing its patented synchronization and positioning system. The company reports filing more than 100 patents and receiving 90 issued patents with zero rejections covering its core technology. This intellectual property foundation strengthens its authority in radio frequency engineering and network-computed positioning.
ZaiNar describes itself as the foundation layer of Physical AI, a market focused on intelligent machines that move and operate autonomously at scale in the physical world. According to the company, AI systems have historically lacked centralized, continuously synchronized, sub-meter accurate location data necessary for reliable physical coordination. By converting existing wireless infrastructure into a sensing platform, ZaiNar transforms global connectivity networks into a persistent spatial awareness layer. The system is protocol-agnostic and compatible with 5G, WiFi, private cellular networks, and future wireless standards. This infrastructure-first model reduces the need for additional hardware deployment.
The company also states that it is deployed and operating today across healthcare, construction, smart city, and industrial environments on multiple continents. ZaiNar reports securing more than $450 million in contracts and memoranda of understanding, with additional carrier and enterprise partnerships expected to be announced. The platform enables applications such as locating medical devices in hospitals and improving safety on construction sites through precise positioning. These use cases demonstrate immediate commercial relevance rather than theoretical capability. The announcement emphasizes that the spatial awareness layer required for Physical AI runs on infrastructure already deployed worldwide.
With over $100 million in investment and a valuation above $1 billion, ZaiNar’s emergence signals a major shift in how wireless networks can be used beyond communication. By solving sub-nanosecond time synchronization, the company claims to unlock real-time spatial intelligence at global scale. As industries increasingly demand accurate, low-power, continuous positioning data, ZaiNar’s platform positions itself as critical infrastructure for the next generation of AI-driven systems. The February 2026 announcement establishes ZaiNar as a leading player in the evolving Physical AI and wireless sensing market.
