Endra is a Swedish AEC software startup that uses AI to automate mechanical, electrical, and plumbing (MEP) design for commercial buildings. Engineers upload a 3D architectural model into Endra, select building code requirements and system type, and the platform generates the engineering model along with the necessary calculations and documentation. Endra integrates with Autodesk Revit, the industry-standard CAD tool, and says it can cut the time to design a code-compliant electrical system for a 500,000-square-foot commercial building from roughly two months to less than a day. Founded in October 2024 and launched in August 2025, Endra had a waiting list of more than 600 companies across 90+ countries. In December 2025 it raised a $20M seed round led by Notion Capital with participation from Norrsken VC and angel investors.
