Stockholm-based Endra has raised a $20 million seed round led by Notion Capital, with strong participation from Norrsken VC, just six months after closing its pre-seed. Founded to automate one of construction’s most time-intensive bottlenecks, Endra builds an AI-powered platform that converts architectural 3D models directly into fully designed, code-compliant MEP systems—covering electrical, ventilation, fire safety and cabling—compressing months of manual engineering work into hours. The new funding will be used to scale its engineering and AI teams, expand internationally with new offices, and accelerate product development as it begins onboarding customers from a global waitlist that has grown rapidly since launch, reflecting mounting pressure on the construction sector to deliver faster, more predictable and lower-carbon projects at scale.
Founded by Niklas Lindgren and Anton Juric, Endra is targeting a persistent productivity gap in the global construction sector. While demand for new buildings and infrastructure is accelerating—driven by urbanisation, energy transition requirements and data centre expansion—engineering workflows have remained largely manual and fragmented. MEP design in particular often requires large consultant teams and months of iterative work before projects are ready for construction.
Co-Founder & CEO Niklas Lindgren explains: “The world is entering a period of rapid and unprecedented construction activity. Workflows that currently take many months are completed in a matter of hours with Endra. This marks a clear before-and-after moment for a global MEP engineering sector that represents 5–6% of the total building construction industry.”
Endra’s platform automates this process by ingesting an architect’s 3D model and generating complete, code-compliant MEP designs, including layouts for lighting, power, ventilation, cabling and fire safety systems. The software produces clash-free 3D models alongside drawings and calculations, aiming to reduce both design time and the risk of downstream errors. According to the company, early pilots have demonstrated efficiency gains of up to 70 times compared with traditional workflows.
Co-Founder & COO Anton Juric adds: “Endra is taking on one of the hardest technical problems in the built world. Demand grew so fast that we had to cap pilots and focus on a select group of leading partners. Now that we’re onboarding customers, the momentum is accelerating even more.”
The funding round follows a rapid increase in interest since Endra onboarded its first customers in August. The company says more than 600 engineering and construction firms across over 90 countries have joined its waitlist, prompting it to limit early pilots while it prepared the product for broader rollout. Demand has been particularly strong from firms working on complex projects where speed, coordination and energy efficiency are critical.
Investors point to the scale of the problem Endra is addressing. The construction industry is expected to significantly increase output over the coming decades while simultaneously retrofitting existing buildings to meet stricter climate standards. Yet productivity growth has been minimal for years, and shortages of skilled engineers are worsening in many markets. Automating design stages such as MEP is increasingly seen as one of the few levers available to close this gap.
Norrsken VC Partner Alexander Danielsson says: “Doubling down on Endra only six months after leading their pre-seed was an easy decision. The team has made rapid progress, bringing traditionally 2D workflows into a fully automated 3D environment and attracting exceptional demand from major consultancies.”
With the new capital, Endra plans to expand its engineering and AI teams, open offices in multiple countries and accelerate development of its full product suite. The company is also preparing for wider customer onboarding, moving from controlled pilots to active deployments across different regions and building types.
As pressure mounts on the construction sector to deliver faster, greener and more predictable projects, Endra is positioning its software as core digital infrastructure for engineering teams—one designed to scale alongside a global building boom rather than be constrained by it.
