What Arent does
Arent Inc. is a Tokyo-based digital technology company founded in July 2012 (originally as CFlat Corporation) that focuses on digital transformation (DX) of the construction industry. The company is organized around two pillars: a DX Business delivering end-to-end consulting, proof-of-concept, and system development services to enterprise construction clients, and a Product Business that develops and commercializes proprietary AI-powered SaaS. Arent is publicly listed on the Tokyo Stock Exchange Growth Market (ticker 5254) since March 2023 and operates through wholly-owned subsidiaries in the United States (Arent Solutions Inc., San Diego, established November 2025), Spain (Arent Software S.A., November 2025), and Vietnam (Arent Vietnam, data processing and operational support).
The company's core technology integrates AI with BIM (Building Information Modeling), 3D CAD, and mathematical optimization to automate construction industry workflows. Its product portfolio combines core proprietary offerings — PROCOLLA (AI cloud process management co-developed with Obayashi Corporation), Lightning BIM AI Agent (a Revit add-in enabling AI to operate Revit), PlantStream (3D CAD with automatic pipe routing at 1,000 pipes per minute), KageMee (AI meeting assistant with real-time construction terminology support), and BizGenie (generative AI platform) — with specialized add-ons and a portfolio of acquired brands covering cost management (Dot Genka, ranked #1 in Japan for seven consecutive years), progress management (Genba Navi, chosen by 80% of major general contractors), structural design, and field work attendance. Documented performance outcomes include a 90% reduction in rebar arrangement work (Lightning BIM Automatic and Optimal Rebar Layout), 1,000 pipes/minute routing speed (PlantStream), and two granted patents covering construction progress management and Setting Optimization Technology.
Arent's business model is anchored in enterprise SaaS subscriptions (annual, predominantly quote-based for enterprise SKUs, with one product publicly disclosed at ¥840,000/year ex. tax), DX consulting and project-based professional services engagements, and channel/training revenue via a partner program that trains 'accompanying construction DX human resources' (notably with World Corporation). Go-to-market combines enterprise field sales targeting Japanese major general contractors (Obayashi, Shimizu, Takenaka, Taisei, Daito Trust, Kanadevia, Kinden, and others), product-led growth via dedicated product websites (procolla.com, lightningbim.com, plantstream3d.com, kagemee.com), strategic channel partnerships for international expansion (Tecnoconsult in the Americas), and direct in-market presence via the new US and Spain subsidiaries.

Arent competitors and assessment
Company assessmentEmerging players
- ALICE Technologies: ALICE Technologies applies AI-driven optimization to construction project scheduling and what-if scenario planning. Comparable to Arent's AI Boost strategy and process optimization work (rebar layout, pipe routing), though focused on schedule rather than physical design automation.
- Buildots: Buildots uses AI computer vision to compare 3D BIM models with on-site reality capture for progress tracking. Comparable to Arent's PROCOLLA and Genba Navi progress management offerings - both target general contractors seeking automated progress validation and BIM-to-site reconciliation.
- OpenSpace: OpenSpace uses AI and 360° site capture to automate construction progress tracking and as-built documentation. Comparable to Arent's PROCOLLA progress management vision - both apply AI/capture technologies to address information sharing delays and progress tracking on construction sites.
- Holcim Solutions and Products (incl. legacy construction tech) / DroneDeploy: DroneDeploy provides reality capture, drone mapping, and site analytics for construction and infrastructure. Comparable to Arent in applying digital capture/AI to construction sites for progress and quality insights, though DroneDeploy is more site-capture-led while Arent is more process- and BIM-led.
Broad incumbents
- Procore Technologies: Procore is a leading construction management SaaS platform covering project management, quality, safety, and financials for general contractors and owners. It is broadly comparable to Arent in serving Japanese-style general contractors with cloud project workflows, though its footprint is global and its scope is wider than Arent's BIM/process-management focus.
- Nemetschek Group: Nemetschek is a major AEC software group whose brands (Graphisoft, Bluebeam, Solibri, dRofus) cover BIM, design collaboration, and model coordination. Comparable to Arent in serving the BIM-heavy design and construction ecosystem, particularly as a competitor in BIM add-in and workflow tooling.
- Trimble Inc. Trimble offers a broad construction technology portfolio spanning BIM, project management, estimating, and field solutions (e.g., Trimble Connect, Viewpoint). Comparable to Arent in targeting general contractors and project-based workflows, but at much larger scale and global footprint.
- Bentley Systems: Bentley Systems provides infrastructure engineering software (OpenRoads, OpenPlant, ProjectWise) widely used in plant, transportation, and civil infrastructure. Comparable to Arent's plant design vertical (PlantStream, ASPO) where both address process plant piping and infrastructure project workflows.
- Autodesk Construction Cloud: Autodesk is the dominant provider of BIM software (Revit, AutoCAD Plant 3D) on which Arent's Lightning BIM, PlantStream, and ASPO products are layered. As the underlying platform owner, Autodesk is the most important peer/ecosystem partner and competitor for Arent's core workflow products.
Direct peers
- RIB Software (Schneider Electric): RIB Software (now part of Schneider Electric) provides construction-specific SaaS including estimating, project management, and BIM-based workflows (iTWO). RIB is a direct competitor to Arent in serving construction firms with integrated estimating and project management software, with comparable target customers.
