About Dalus

Dalus is an AI-powered systems engineering software to model/validate complex systems for aerospace/defense/robotics and other mission-critical industries. With Dalus, engineers can seamlessly trace requirements, perform analyses, and update information in real-time. This ensures that every team member stays aligned and informed, reducing inefficiencies and enabling faster iterations. With AI at our core, users can analyze hundreds of pages of existing engineering documentation and requirements to generate or retrieve information about the system model they are building in Dalus. We started working together on Dalus in spring 2024 after Eliot quit his job at Aerojet Rocketdyne (L3Harris) where he worked as a test/systems engineer. He experienced first-hand how silos and poor communication reduced the productivity and efficiencies in the teams he worked at. We love working with companies tackling complex engineering systems, whether they be startups just getting their feet wet or large organizations like Israel Aerospace Industries (Our design partner and biggest aerospace/defense company from Israel) Read why we started Dalus: https://dalus.io/articles/why-dalus
