Value proposition
Reduces the time required for building engineering from weeks to minutes, addressing the global shortage of engineers while improving design accuracy and reducing construction costs.
Products and solutions
Generative MEP Design Engine (Automated layout of piping, ductwork, and electrical systems), AI-Driven Engineering Workflow Automation, Automated Compliance & Building Code Integration, Material and Energy Optimization Dashboard
Unique value
Unlike traditional CAD software that acts as a digital drawing tool, Endra uses generative AI to autonomously 'solve' engineering problems, creating optimized system layouts based on building constraints without manual drafting.
Target customer
Mechanical, Electrical, and Plumbing (MEP) engineering firms, construction companies, and large-scale real estate developers.
Industries served
Construction, Architecture & Engineering (AEC), Real Estate Development, PropTech
Technology advantage
The platform utilizes proprietary computational geometry and high-performance infrastructure built by a technical team with experience in Goldman Sachs' high-frequency trading systems, allowing for rapid processing of complex physical constraints.
How they differentiate
Endra differentiates by moving beyond simple 'generative drafting' to 'autonomous engineering.' Utilizing high-performance infrastructure and computational geometry (developed by a team with Goldman Sachs high-frequency trading backgrounds), it solves complex physical constraints in MEP systems rather than just providing visual layouts.

Major milestones
Successfully exited stealth mode in May 2025 with a €3M pre-seed round led by Norrsken VC., Secured a strategic partnership with Rejlers to pilot AI-driven MEP design (Sept 2025)., Closed a record-breaking $20M seed round in December 2025 led by Notion Capital., Announced strategic collaboration with AFRY for AI in building design (April 2026)., Closed $50M Series A led by Andreessen Horowitz with Notion Capital and Norrsken VC (June 2026), bringing total funding to ~$74M., Opened offices in New York, San Francisco, and London (July 2026); Epoch electrical-module launch event in Las Vegas (Sept 14, 2026).
Growth metrics
Raised $74M in ~13 months culminating in $50M Series A (Jun 2026); converting 600+ company waitlist (90+ countries) to commercial users with reported 10x+ YoY revenue growth; expanding hiring across Stockholm, NYC, SF, and London; team grew into the tens (Caplight ~29 as of Aug 2026).
Market positioning
Premium AI-automation disruptor in the AEC (Architecture, Engineering, and Construction) sector.
Geographic focus
Global: HQ Stockholm; North American HQ New York, West Coast office San Francisco, UK office London (opened Jul 2026); early access EU/UK/US; expanding continental Europe and Middle East.
Patents and IP
Proprietary generative AI models and trade-secret algorithms; no specific public patent filings disclosed as of late 2024.
About Niklas Lindgren
Niklas Lindgren is a serial entrepreneur who previously co-founded Sectragon, a physical security and access control company that was acquired by Prosero Security Group. He has a background in law and business development, and he founded Endra to solve the manual inefficiencies he observed in building engineering workflows.
