Inversion

Inversion is a Los Angeles-based aerospace and defense company founded in 2021 by Austin Briggs and Justin Fiaschetti, building a new class of highly maneuverable reentry vehicles. Its flagship Arc is an autonomous, reusable, low-cost space-based delivery vehicle designed to store cargo in orbit and deliver it with precision to anywhere on Earth in under an hour, descending under parachutes using non-toxic propellants so crews can approach it immediately on landing. The company also develops hypersonics and space-based interceptor technology and flew its first reentry capsule, Ray, as an early technical demonstrator. Inversion has raised roughly $54M to date, including a $44M Series A led by Spark Capital and Adjacent with participation from Lockheed Martin Ventures, Kindred Ventures, and Y Combinator. It does not currently publish a public developer API; this profile tracks the company for the API Evangelist network.

Inversion is profiled on the APIs.io network. Tagged areas include Company, Aerospace, Defense, Space, and Reentry Vehicles.

Inversion’s developer surface includes engineering blog and 4 more developer resources.
