What they do

Problem

Satellite-like services are costly and inflexible to deploy and cannot easily provide targeted, persistent coverage on demand.

Solution

Radical builds autonomous high-altitude atmospheric platforms (StratoSats) that deliver persistent earth observation, connectivity, and other infrastructure services without rocket launches or fixed orbits.

Who it's for

Governments, enterprises, and operators needing on-demand persistent coverage for earth observation and connectivity.

Founders

James Thomas

Founder

Co-Founder & CEO at Radical (W23) - Radical makes high altitude solar-powered aircraft. Our aircraft are able to fly continuously in the stratosphere without landing. They provide an inexpensive, zero-emissions way to connect and observe earth like never before. Prior to this I worked at Amazon Prime Air for six years (doing aerodynamics and aircraft design for delivery drones).
