Xwing announced that it has raised $40 million in funding at a $400 million valuation. Led by Blackhorn Ventures, with participation from ACME Capital, Loup Ventures, R7 Partners, Eniac Ventures, Alven Capital and Array Ventures.

Xwing has completed the world's first fully autonomous gate-to-gate demonstration of a commercial cargo aircraft that saw a Cessna Grand Caravan 208B leave the gate, taxi, take-off, land and return to the gate entirely on its own. The flight took place in February 2021 and was remotely monitored from the company's mission control center in Concord, California. All air traffic control interactions were done from the ground.
