What The Fourth Law does

The Fourth Law's autonomy module takes over control for the final stage of a flight using onboard AI rather than a remote pilot, and the company also offers autonomy simulation for training and testing. Its Zerov-8 interceptor is built to catch Shahed-type attack drones in the air.

The secret

Only the last 500 meters of a flight need to be autonomous. Handing that stretch to onboard AI defeats jamming and the loss of the radio link, which is why Ukrainian drone makers now ship aircraft with TFL-1 built in.

Why NZVC invested in The Fourth Law

We backed The Fourth Law because autonomy is becoming the decisive capability for robotic and unmanned systems, particularly where communication links are jammed or unavailable. The founder has built and shipped hardware at global scale before, which is rare and hard-won experience for a company operating at the edge of what autonomy can do. Software that meaningfully raises mission success rates for a small increase in cost is the kind of clear, measurable value that a market moves toward quickly.
