9 years in stealth is not hiding. It is calibration. It is tightening the signal until the noise taps out. ZaiNar, based in Belmont, CA, just surfaced with over 100 million dollars in investment and a valuation above 1 billion dollars. That is not a warm welcome. That is a statement. Physical AI is the arena, and ZaiNar is building the layer most people forgot to imagine. Not another device. Not another dashboard. The air itself becomes infrastructure.
Founded in 2017, ZaiNar began when PhD engineers and MBA business leaders met at Stanford University and decided wireless networks were underachieving. While the world obsessed over apps and satellites, they obsessed over time. Sub-nanosecond synchronization. Phase-based precision. The kind of math that makes GPS look like it showed up late to the meeting.
The platform turns existing 5G and WiFi networks into a spatial sensing system that continuously knows where everything is. No satellites. No cameras. No extra hardware. No drain on device power or compute. Indoors. Outdoors. Through walls. Around corners. If data is the new oil, ZaiNar just figured out the geology of space itself.
Daniel Jacker, Co-Founder and CEO, Philip Kratz, Co-Founder and CTO, and Jake Levy, Co-Founder and COO, built this quietly for nearly a decade before stepping into the light in February 2026. The result is more than 100 patents filed, 90 issued, and 0 rejections. In RF engineering, that is not luck. That is discipline with teeth.
More than 450 million dollars in contracts and memoranda of understanding are already in motion, with deployments across construction, healthcare, smart cities, and industrial environments on multiple continents. Construction crews stay clear of hazard zones. Healthcare teams find critical devices without scavenger hunts. Autonomous systems coordinate with spatial awareness that feels less like guesswork and more like choreography.
The board and cap table are not light reading. Steve Jurvetson, Board Member at ZaiNar and SpaceX. Andreas Weigend, Advisor and former Chief Scientist at Amazon. Jerry Yang of AME Cloud Ventures. Tom Gruber, co-founder of Siri. Jaan Tallinn of Skype and Metaplanet Holdings. Nicholas Pritzker of Tao Capital. When that caliber of mind circles a company, it is not for vibes. It is for velocity.
ZaiNar does not add hardware. It adds intelligence to infrastructure the world already paid for. Protocol-agnostic across 5G, WiFi, and private cellular. A sensing layer built on radio waves already in motion. Physical AI becomes less about robots and more about awareness. Less about dashboards and more about decisions made in real space, in real time.
Physical AI is described as a foundation for one of the largest technology markets ever created. ZaiNar is betting that intelligence will not just live in the cloud or on the device, but in the space between them. In timing. In synchronization. In the quiet math most people overlook.
