What Struck does

Struck (legal entity Struck.Build B.V.) is an Amsterdam-based AI software company founded in 2023 by Max van Riel (CEO, ex-ING/Payconiq/Eagle Eye Networks) and Nikhil Nagaraj (CTO, ex-ML6). The company operates a SaaS platform called Unravel that applies generative and retrieval AI to building regulation compliance, allowing architects, developers, municipalities, and consultants to query a consolidated library of national, provincial, and municipal building codes and receive cited, legally traceable answers in natural language.

The product suite is anchored by four modules: an automated Permit-Free Check (Vergunningsvrij Check) that compresses manual review from approximately 30 minutes to 30 seconds; a Technical Regulations AI Assistant that answers building code questions with source citations; 3D Zoning Plan lookup with downloadable DXF files; and a Regulation Library exposing 2M+ pages of building legislation across nine European countries (Netherlands, UK, Spain, Germany, Denmark, Poland, Norway, Belgium, Switzerland). Differentiated features include a Revit plugin for Bbl Article 4.147 daylight compliance, an overheid.nl Regelzoeker integration, automated monument and protected-townscape recognition, multilingual chat support, automated municipality letter generation, and a proprietary "Super Prompts" structured-prompting layer designed to enforce consistent, citation-grounded outputs. The platform is ISO 27001 certified and GDPR compliant.

Struck operates a freemium-to-enterprise SaaS model: free self-serve permit-free checks feed a sales-led enterprise motion with demo-based conversion, team/collaboration features, and organization-branded PDF reports. GTM combines direct enterprise sales, event presence (Vereniging BWT Nederland, InterGarant Groep roadshow), and channel/reseller distribution via partners including Centric, InterGarant, and VNG. The company reports 5,000+ users and has raised approximately €2.25M cumulatively across a €100K Antler pre-seed (May 2024), a €150K Rabobank Innovation Loan (May 2024), and a €2M seed round led by Value Factory Ventures (November 2025) earmarked for European expansion.

Scale indicators13 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Procore: Procore is the leading construction management SaaS platform serving general contractors, owners, and specialty trades. While not specialized in regulatory compliance, its broad AEC footprint makes it a natural incumbent that could expand into building code intelligence to defend its position.
• Autodesk Construction Cloud: Autodesk Construction Cloud is the dominant BIM and construction management platform, including Revit (which Struck integrates with via plugin). As the broad incumbent in AEC software, Autodesk could bundle compliance features or pre-empt Struck's Revit daylight plugin expansion.

Emerging players

• Archdesk: Archdesk provides SaaS tools for architects and engineers to manage projects, drawings, and specifications. It targets Struck's primary persona (architects) and could integrate or build competing compliance features into its document-centric workflows.
• LetsBuild: LetsBuild (formerly GenieBelt) is a Danish construction project management platform. It targets similar general contractors and developers as Struck's downstream users and could expand into AI-driven compliance adjacent to its current scheduling and quality workflows.
• nPlan: nPlan applies AI to construction project scheduling and risk analysis. It serves a different point in the construction lifecycle (planning vs. compliance) but targets the same digitally underserved AEC market with AI-first workflows.
• PlanRadar: PlanRadar is an Austrian SaaS for construction and real estate documentation, defect management, and inspections. It overlaps with Struck on compliance-related workflows for builders and facility managers, though without Struck's AI-native regulatory focus.
• Buildots: Buildots applies AI to construction progress tracking via computer vision on site captures. While focused on execution rather than permitting, it represents the broader AI-for-AEC category and competes for the same construction-tech buyer mindshare.

Direct peers

• Brainial: Brainial is a Dutch AI company explicitly referenced alongside Struck as a comparable AI application in the construction sector. It applies AI to construction-sector document workflows, sharing Struck's vertical-AI approach to AEC compliance.
