About

Endra is a Stockholm-based platform that uses AI to automate mechanical, electrical, and plumbing (MEP) design for commercial buildings, the engineering work that determines how heating, power distribution, lighting, fire alarms, and water systems get specified across every floor of a project. It integrates with Autodesk's Revit, the standard CAD tool used across the MEP industry, so engineers can upload a 3D architectural model, select the building code requirements and system type they want to design, and have the platform generate the engineering model along with the necessary documentation. The pitch to MEP firms, general contractors, and developers is straightforward: a process that traditionally takes two months of specialized engineering work gets compressed to less than a day. This launch marks the company's Series A. Endra raised $50 million led by Andreessen Horowitz , on top of a prior $20 million seed led by Notion Capital with Norrsken VC and a roughly $3.4 million pre-seed, bringing total funding to $74 million inside its first 18 months. The timing matters because the built world still relies on infrastructure software predating some of its users , and large engineering consultancies are now actively rethinking how AI fits into the design stack rather than experimenting around the edges. The four co-founders are Niklas Lindgren (CEO), Anton Juric, David Rydberg, and Gustav Hammarlund. Lindgren and Juric are childhood friends with prior startup experience and roots in MEP consulting, joined by David Rydberg and Gustav Hammarlund, who worked together on Goldman Sachs' low-latency trading desk. That mix of domain empathy and systems engineering shows up in the product surface, which targets the rote, repetitive portion of MEP work (placing devices, running circuits, checking code compliance) so engineers can spend more time on analysis and design intent.

ok wait, a wine cellar with no heat in Stockholm? that's not a founding story, that's a hostage situation with extra steps.

Tomás Vidal1d ago

the best products are built in rooms cold enough to keep you honest. congratulations on the wine, even if you never drank it.

Femi Akindele1d ago

MEP plans on-chain when? imagine HVAC ducts as NFTs, each elbow joint its own collectible.

Mira von Berg1d ago

the cold open with the empty wine cellar shot was genuinely cinematic, but the cut to the office b-roll felt like 4 seconds too long. tighten that and it's a banger.

Han Woo-jin1d ago

hot take: MEP is the most underrated wedge into AEC software and nobody outside the industry will understand why this matters for another 18 months.

Rahul Venk1d ago

love it, now add a clash detection mode that explains in plain english why the duct can't go there. would close 10 enterprise deals next quarter.

quick question, does it actually read existing Revit families or does the engineer still have to rebuild the library from scratch? asking because my last internship that was the dealbreaker.

Noor Hadid1d ago

the demo videos always look magical until you load a real-world messy as-built PDF from 1987 and the whole thing crumbles. happy to be proven wrong though.

Lukasz Or1d ago

every AEC tool claims they'll replace the MEP engineer and every one of them ends up being a glorified Revit plugin. prove me wrong.

Kofi Asante1d ago

curious what the underlying approach is for code compliance reasoning, is this constraint solving on top of an LLM or something closer to a graph-based representation of the building systems?

Elif Demirkan1d ago

3 weeks out from launching something adjacent and watching this announcement is making me question every life choice in the best way.

Prash B.1d ago

founded in an unheated wine cellar, raised from a16z, the pipeline from suffering to term sheet remains undefeated.

Sigrid Halvorsen1d ago

this might genuinely be one of the last MEP tools that ships without an autonomous agent doing the routing. enjoy the click-to-confirm era while it lasts.

Camille N.1d ago

compared to the last handful of AEC launches in this category the production value here is in a different tier. most of them look like they were edited in Google Slides.
