os.build ✓

os.build is an AI-powered suite of AEC tools from neoBIM GmbH, and it's worth stating plainly upfront that this product has changed shape since it first launched: it was originally introduced as "neoBIM buildOS" and pitched, including in some of our own earlier coverage, as an AI-first BIM authoring platform built for agentic AI to model alongside humans. That framing has not held up under closer inspection of the vendor's own current site. The company has since rebranded its domain from neobim.ai to os.build, and the product it actually ships today is a different, more modular thing: a suite of separate, purpose-built tools -- Gen, Tender, Insider and Mind -- each solving a specific, narrower AEC workflow problem rather than one unified BIM authoring platform for AI agents. Some earlier trade-press coverage (including an AEC-tech outlet's editorial description of neoBIM's in-development BIM authoring architecture as "replacing static, monolithic files with dynamic, semantic data streams") appears to have been describing an aspirational, not-yet-shipped direction rather than an actual, named, shipping product -- worth flagging clearly, since it's an easy claim to repeat without checking against what's currently live.

The company itself, neoBIM GmbH, is registered in Karlsruhe, Germany (company register HRB 749693, Amtsgericht Mannheim), with its official incorporation dated January 11, 2024. Its Managing Director is Moritz Luck, whose prior credential is genuinely notable: he co-founded Enscape, the real-time rendering plugin that became one of the most widely adopted visualization tools in architecture before Chaos Group acquired it. That's a real, verifiable pedigree in building AEC software that architects actually adopt at scale, which is precisely why neoBIM's early positioning attracted attention from AEC trade press covering AI tools at industry events like the AIA National Conference. Dr.-Ing. Florian Marthaler holds an authorized-signatory (Prokurist) role at the company per its own legal imprint.

Of the four current tools, Gen is the most developed and most clearly the flagship product: it's a site-feasibility and generative-design tool that automatically pulls zoning, density and parcel data for a given site, generates multiple massing variants against that data, runs live compliance checks against zoning rules as a massing changes, and produces a live financial pro forma covering gross development value, yield, cost per square meter and return on investment -- essentially collapsing what would normally be a multi-day feasibility study spanning a planner, a financial analyst and a designer into a single automated first pass. Gen also accepts custom floor-plan uploads and produces renderings, with outputs including a compliance report, financial summary and 3D model; on its Pro tier, it exports directly to Revit and IFC rather than being a dead-end feasibility tool disconnected from the rest of a project's BIM pipeline.

Tender is a narrower, more specific tool: it parses contractor bids submitted as PDFs, emails or scanned documents and turns them into unified price-comparison matrices, automating what's normally a tedious manual process of re-keying numbers from inconsistently formatted bid documents into a spreadsheet for like-for-like comparison. Insider is narrower still and geographically specific -- it monitors more than 250 German municipal council meetings for zoning changes and design-competition announcements, functioning as an early-warning system for firms that want to catch upcoming opportunities or regulatory shifts in specific German municipalities before competitors do; it's hosted on a separate subdomain (neosearch.neobim.ai) rather than fully folded into the main os.build product experience yet. Mind is the most general-purpose of the four: an AEC "knowledge assistant" combining a centralized project dashboard, file and version storage, RFI/submittal tracking, contract risk flagging, team workload visibility and a natural-language AI assistant that can answer questions in plain English against a firm's own project data.

Pricing varies significantly by tool and is, unusually for an early-stage product suite, mostly published outright rather than gated behind a universal "contact sales" wall. Gen has a Starter tier at €99/month (20 reports, PDF output only) and a Pro tier at €499/month (adding Revit/IFC export and custom plans), with Enterprise as a custom quote. Mind has a genuine free tier (40GB storage, limited AI) and a Premium tier at $60/month (unlimited storage, full AI capability), also with a custom Enterprise option. Tender and Insider don't display public pricing, and despite Gen's published price list, both Gen and Insider are described elsewhere on the site as being in waitlist or early-access status -- worth reading literally: a published price on a page doesn't necessarily mean the tool is in unrestricted general availability yet, and firms interested in Gen specifically should confirm current access status directly with neoBIM rather than assuming instant self-serve signup.

On integrations, Gen exports to Revit and IFC on its Pro tier, plus PDF on all tiers, and Mind integrates with Microsoft 365, Teams, Zoom and references Autodesk/BIM 360 as file types it can handle -- though it's worth being precise that handling Revit or IFC files is not the same as a deep, bidirectional platform integration with Autodesk's own construction cloud products, and no such deeper platform partnership is documented on neoBIM's own site. As for customer proof, there is currently none in the form of named companies, case studies or logos anywhere on os.build -- the only social proof on the site is a handful of anonymous testimonials attributed to generic titles like "developer," "Project Manager" and "CEO" rather than named, attributable references, which is a meaningfully weaker form of evidence than the named case studies more established competitors in this catalog publish.

Editor’s takeBIM•STACK editor's take: os.build is a genuinely interesting pivot from an ambitious but vague "AI BIM authoring" pitch toward four concrete, narrowly-scoped tools that each solve a real, specific pain point -- and Gen in particular, collapsing feasibility, zoning compliance and financial pro forma into one automated pass, is a legitimately useful idea for the earliest phase of a development project. The company's founder credibility (Moritz Luck's Enscape track record) is real and should count for something in an evaluation. But firms should go in with clear eyes about where this product actually is right now: no named customers, some tools still in waitlist/early access despite published pricing, and a recent, significant rebrand and repositioning away from the original BIM-authoring pitch. This is an early-stage bet worth watching, not yet a proven platform to build a firm's workflow around.

Because os.build's four tools are narrowly scoped rather than a single sprawling platform, the learning curve for any one of them is relatively shallow -- Gen's workflow (input a site, review generated massing options and compliance/financial output) and Mind's workflow (ask a question in plain English against project data) are both designed around natural-language and guided-input interaction rather than requiring users to learn a complex modeling interface from scratch. Teams already comfortable with a feasibility-study or knowledge-management workflow conceptually should be productive with the relevant tool within their first few sessions, since neither Gen nor Mind expects users to model geometry by hand the way a traditional BIM authoring tool would.

The bigger source of friction for a new evaluator isn't any single tool's interface but understanding the current state of the whole suite: because messaging and press coverage referencing the earlier "buildOS"/agentic-BIM-authoring vision are still findable online even after the pivot to the current os.build tool suite, teams researching the product should be careful to evaluate what's actually live on os.build today (Gen, Tender, Insider, Mind) rather than assuming older descriptions of an AI-BIM-authoring platform still apply. Anyone seriously evaluating this vendor should also confirm current access/waitlist status directly with neoBIM before assuming a listed price means immediate, unrestricted signup, given that Gen and Insider are both described elsewhere on the site as early access despite having public pricing.
