Our Story
Built on Manufacturing Expertise. Focused on What Comes Next.
Founded in 1996 by two manufacturing engineers, Aegis was built on the belief that software should solve real operational challenges, not create new ones. What began with engineering and CAD/CAM solutions has grown into a portfolio that spans manufacturing execution, digital twin simulation, advanced planning, operational intelligence, and AI. Throughout that evolution, one principle has remained constant: helping customers make better operational decisions using software grounded in the realities of how work is actually performed.
- 2,200+ factory deployments worldwide
- Built to support operations from a single site to global manufacturing enterprises
- From execution to simulation, planning, intelligence, and AI
