Reditus Space

Founded in 2024 by Stef Crum and Will Sherman, Reditus Space develops the ENOS platform—reusable satellites that carry customer payloads to low Earth orbit, enable in-space operations, and return finished products to Earth. The company targets microgravity manufacturing applications including drug formulation, optical communications, and semiconductor processing, while also providing routine access to Mach 28+ hypersonic reentry conditions for aerospace and defense testing. Backed by Y Combinator and Antler, the Atlanta-based company raised a $7.1M seed round in December 2025 and is onboarded onto the SHIELD IDIQ contract vehicle.
