Building persistent, high-performance infrastructure in the sky
Radical’s StratoSats are autonomous platforms that provide satellite-like services on demand. They fly within Earth’s atmosphere to provide persistent, high performance infrastructure across applications in earth observation, connectivity, and more. Unlike satellites, StratoSats navigate freely without the need for rocket launches or orbits - reducing costs, increasing flexibility, and ensuring customers get the targeted coverage they need.
Radical builds autonomous, solar-powered StratoSats that fly continuously in the stratosphere to provide high-performance connectivity and observation. Their platform aims to offer flexible, targeted coverage without orbital constraints and includes the Evenstar aerial platform for efficient, cost-effective operation.
StratoSats are autonomous solar-powered aircraft that operate in the stratosphere, designed for persistent flight without landing. They are optimized for connectivity and observation, enabling high-resolution imagery, maritime domain awareness, wildfire monitoring, 5G direct-to-device connectivity, secure borders and approaches, search and rescue support, and climate/emissions monitoring. Evenstar is described as the most efficient, cost-effective aerial platform that increases flexibility, reduces cost, and provides targeted coverage when and where needed.
Who it’s for: Organizations requiring persistent high-altitude connectivity, surveillance, and environmental monitoring, including government/mederal agencies, maritime and border security, disaster response, and large-scale data collection operations.
Some press coverage and prototype flight news; ongoing product announcements and career/newsroom pages indicate active development and signaling traction
AmazonCo-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).

Solar aircraft for connectivity, observation, and sensing, from the stratosphere
Radical builds high-altitude solar-powered aircraft that fly continuously in the stratosphere at ~70,000 ft to provide long-duration coverage for applications like connectivity, imagery, sensing, meteorology, and emergency response. The post announces ongoing hiring and collaboration with customers to deploy and operate these aircraft for months without landing.
