WHO WE ARE
WH4 Inc. was founded on a simple idea: most hard questions come down to Who, When, Where, and What. We build the tools that answer them, combining precision GNSS, modern iOS development, and decades of engineering and security experience. In the lab: Gaussian splatting from 360° field capture, and RTK GNSS beacon hardware.
Based in El Segundo, California.
