Seattle-based Radical says it has raised $4.5 million to support the development of solar-powered, autonomous airplanes that can beam down connectivity and imagery during long-duration, high-altitude flights.
The seed funding round was led by Scout Ventures, with additional funding from other investors including Inflection Mercury Fund and Y Combinator. According to Pitchbook, Radical previously received $500,000 in pre-seed funding from Y Combinator.
Radical’s co-founders are CEO James Thomas and chief technology officer Cyriel Notteboom. Both founders are veterans of Prime Air, Amazon’s effort to field a fleet of delivery drones. They left Amazon in mid-2022 to found Radical — and the aerospace startup is just now coming out of stealth.
Thomas told me that Radical will use the fresh investment to expand its team, which currently amounts to four people. “We’re still a small team, but we’re growing very quickly,” he said. “We’re currently hiring. Those positions are up on our website, with more to come.”
