Endra announced Power Studio and the acquisition of Planlabs on 16 September 2026. The release says Power Studio “launches at Epoch, Endra’s own launch event, held in Las Vegas on the eve before Autodesk University” — a conference this newsroom covered the same week. Financial terms of the acquisition were not disclosed, and this newsroom found none reported elsewhere.
Power Studio is the product: an agentic platform for electrical engineering design. Planlabs is the purchase: a Swiss lab, founded in 2024, whose technology the release describes as “geometry, data and physics engines [that] design mechanical systems automatically and check them against physical constraints.” Startupticker, the Swiss startup publication, reported the deal on 17 September and put the team joining at five people.
Put those two facts next to each other and the announcement stops being a product launch. It is a map of how a company intends to get to MEP — mechanical, electrical and plumbing — without waiting to build three disciplines in sequence.
One Letter at a Time
MEP is an acronym that hides how separate its three parts are in practice. Electrical design, mechanical design and plumbing design use different physics, different codes and, usually, different engineers. A platform that claims to do MEP is claiming three things, and building all three well at once is a considerably larger undertaking than building one.
Endra’s answer, as of this week, is to build electrical, buy mechanical and schedule plumbing. The release sets out the whole sequence in one sentence: “A plumbing module will follow in 2027, and the acquisition of Planlabs adds mechanical engineering to the roadmap.” Tech.eu reported the same 2027 date for plumbing.
Before Power Studio, the discipline Endra had actually shipped was narrower still. Endra’s own site leads on fire alarm systems, electrical systems, containments and conduits, and lighting, and lists HVAC, plumbing and security as forthcoming. It names the standards it supports by number — SBF 110:8, NFPA 72, BS 5839, DIN 14675 — which is the kind of specificity that is easy to check and therefore worth noticing in a category that often markets itself in adjectives.
Analysis, not reporting: the fire-alarm starting point is a sensible one for automation, because it is the most rule-bound slice of an already rule-bound discipline. Detector spacing and coverage are largely determined by geometry and a code table. That is the part of engineering judgment that is least like judgment — which is also why success there does not automatically transfer to the rest of the acronym.
What Power Studio Claims
The release names five components: Playbooks, which store a firm’s engineering standards; Agents, which take on defined tasks; Simulation, described as physics-engine validation; Type Rooms, which replicate a design across matching spaces; and a document engine producing Revit models, diagrams, schedules and bills of materials.
The headline performance claim, in the release’s exact words: “A code-compliant electrical design for a 500,000 square foot commercial building, work that traditionally takes around two months, can be completed in less than a day.”
That is the company’s figure, and it is reported here as the company’s figure. The release does not say which building, which code jurisdiction, whether the comparison is against a specific benchmark project or an industry rule of thumb, or what proportion of the output required engineer correction. “Code-compliant” is doing a great deal of work in that sentence, and nothing in the announcement establishes who checked.
Chief executive and co-founder Niklas Lindgren framed the Playbooks piece this way: “Endra takes care of the repetitive work, and gives the engineers back the time for judgment and design. A firm’s engineering judgment is its product, and Playbooks let a firm hold that as a standard its whole team designs against, with the engineer setting the requirements and signing off at every stage.”
The Acquisition Is Technology and Five People
Planlabs was founded in Switzerland in June 2024. The release describes it as a technology and talent acquisition, and puts the team at five, with backgrounds in mathematics and computer science. AEC Magazine reported the same team size and the same founding year.
Rea Sodero, Planlabs’ co-founder and chief executive, in the release: “We started Planlabs with the belief that mechanical systems can be engineered fundamentally differently, automatically generating coordinated, collision-free solutions while keeping the engineer in control. With Endra, we have found a team that shares this vision and has the ambition, technology and reach to bring it to engineers around the world. Together, we have the opportunity to build something much bigger: a platform that transforms how every MEP discipline is engineered.”
Five people and a physics engine is not an acquisition that moves a revenue line. It is an acquisition that moves a roadmap — which is the honest reading of a deal where no terms are disclosed and the acquirer announced a $50 million Series A in June.
The Customers Named, and What That Does and Does Not Establish
The release states: “Endra works with enterprise consulting firms including AtkinsRéalis, Ramboll, Buro Happold, Hoare Lea and AFRY.” Endra’s own site displays those same names as logos, alongside Tetra Tech and Rejlers.
Those are large, credible engineering consultancies, and a company does not usually put that set of names in a press release lightly. What the release does not say is what any of them are doing with the software — pilot, single office, single discipline, or production use across the firm — or when they started. A logo establishes a relationship, not a deployment, and this newsroom has not confirmed the scope of any of them.
Where This Sits
Endra’s $50 million Series A led by Andreessen Horowitz, which this newsroom covered in June, bought the company roughly a quarter before it had to show what the money was for. This is the answer, and the interval between raising and shipping is a short one.
The broader pattern is familiar from elsewhere in design software. Motif’s agent-native BIM authoring launch attacked the architectural side of the same problem — a modelling environment designed around agents rather than retrofitted for them — and Autodesk spent its own user conference the same week arguing that the value is in connected project data rather than in the agents themselves. Endra’s bet is narrower and, in one respect, easier to judge: MEP output is drawings, schedules and bills of materials that an engineer either stamps or does not.
What Is Not Known
The release does not state the financial terms of the Planlabs acquisition, and no outlet this newsroom checked reported a price. It names a launch event for Power Studio — Epoch, in Las Vegas — but gives no customer availability date, no pricing and no regional rollout, and does not say whether the product is generally available or in limited release. It gives no accuracy figure, error rate or engineer-correction rate against the speed claim, and no named project behind the 500,000-square-foot comparison. Planlabs’ prior funding and investors, if any, are not stated in the release and were not reported in the Swiss or trade coverage this newsroom reviewed.
The company describes Power Studio as “the first AI platform purpose-built for electrical engineering,” and its site describes itself as “the world’s first purpose built platform for MEP designers.” Both are Endra’s characterisations of its own product. This newsroom has not attempted to adjudicate either and does not repeat them as fact.
The checkable facts are the 16 September 2026 announcement, the Power Studio launch, the acquisition of Planlabs AG of Aarau with a five-person team joining Endra, the undisclosed terms, and Endra’s $50 million Series A led by Andreessen Horowitz with earlier backing from Notion Capital and Norrsken VC.
