Kosaint

Kosaint is a Europe-based company in the early stages of developing propulsion and advanced manufacturing systems for next-generation aerospace and defence. Its mission is to help create faster, more scalable ways to design, manufacture and deploy advanced systems, beginning with propulsion. The company brings simulation-driven design, metal additive manufacturing and rapid iteration together in a single development workflow, with a long-term vision spanning propulsion hardware, industrial production and European strategic capability.

Kosaint’s active domains are air and space. Its work includes air-breathing propulsion and unmanned air systems, as well as additive-first propulsion hardware for space applications. Sea and land programs are listed as in development. The company’s capabilities cover high-performance propulsion systems, advanced manufacturing methods for rapid development and scalable production, and production systems designed for repeatable industrial deployment. Its stated engineering principles include minimal part counts, additive-first structural design, repeatable performance, distributed manufacturing and short iteration cycles. Kosaint also welcomes contact about partnerships, research and collaboration.
