What Temelion does

Temelion is a Paris-based AI software company founded in 2025 that targets medium-sized multi-disciplinary engineering design consultancies (Bureaux d'Études Techniques, or BET) in France. The company provides an AI-powered workflow and documentation assistant that automates repetitive pre-construction tasks — tender viability analysis, technical proposal generation, contractor bid comparison, and document reconciliation — for engineering directors, technical directors, project managers, and junior project engineers working on electrical, HVAC, thermal, and other building specialties.

The platform is architected as an AI orchestration layer that sits on top of existing BIM/CAD environments (Revit, Rhino, IFC, AutoCAD) rather than replacing them. Its technology combines natural language processing, knowledge retrieval, optimization, multimodal document ingestion, and autonomous agentic AI trained on French and European building codes. Core product modules include Go/No Go (tender viability), the Technical Notice Generator (auto-generated compliant proposals), Contractor Comparison (ACT bid analysis), and an Electric Pack module for electrical engineering deliverables in development. The platform also maintains an internal knowledge repository of past-project best practices to enable content reuse across teams.

Temelion operates a sales-led SaaS business model with quote-based pricing and a structured pilot program targeting French BET firms. It is currently in beta with several large engineering and architecture firms in France, with reported pilot outcomes of 30-50% reduction in technical verification time, 10x faster tender analysis, 90% reduction in contractor comparison time, 20% improvement in win rates, and 25% more projects bid on. In September 2025, the company raised €3.2M in seed funding led by 360 Capital with participation from ISAI Build Venture, SE Ventures (Schneider Electric's CVC), Kima Ventures, and construction-sector angels; the capital is earmarked for market entry, team expansion, and commercial rollout in France with subsequent European expansion.

Core offering

Temelion is an AI-powered workflow and documentation assistant for building design engineering firms (Bureaux d'Études Techniques, BET). It automates repetitive pre-construction documentation tasks — including tender analysis (Go/No Go), technical proposal generation, contractor bid comparison, and cross-specialty data synchronisation — by sitting as an AI layer on top of existing BIM/CAD tools (Revit, Rhino, AutoCAD) without replacing them. The platform targets medium-sized multi-disciplinary engineering consultancies in France and Europe.

Functional benefit

Products and services

• Go/No Go Workflow AI-powered bid/no-bid decision tool that analyses tender documents to surface technical requirements, evaluation criteria, and hidden risks. Compares tender specifications with internal benchmarks, past experience, and resource availability so engineering firms can rapidly decide whether to pursue a project. Enables collaborative real-time decisions with customisable evaluation templates.
• Technical Proposals (Notice Technique) AI module that auto-generates compliant technical proposals by extracting and pre-filling content from tender documents using past projects, team information, and brand assets. Flags missing data or regulatory issues and adapts templates to project size, location, and type (residential, commercial, or public).
• Contractor Comparison (ACT Comparison) AI-powered analysis and comparison of contractor bids. Automatically extracts key offer data (quantities, prices, variants, timelines), generates one-click comparison tables, detects technical or financial gaps between bids, and flags inconsistencies or missing data. Produces a structured bid comparison report ready for client presentation.

Quantifiable outcome

• 10x faster speed of analysis; 1.7x faster Bid/No-Bid decisions
• +7 more outcomes

Emerging players

• Buildots: AI-driven construction progress monitoring that compares BIM models to on-site capture. Similar AEC vertical focus and AI-first approach for design and construction workflows, though focuses on execution-phase progress tracking rather than pre-construction documentation.
• nPlan: AI-based construction project scheduling and risk analytics platform. Comparable in applying machine learning to construction planning workflows, though focused on schedule optimization rather than document and tender automation for engineering firms.
• Alice Technologies: AI-powered construction scheduling and what-if scenario planning. Both target the design-and-engineering phase of construction with AI automation, though Alice focuses on schedule generation rather than document generation and reconciliation.
• Avvir: AI platform that verifies BIM models against actual construction to catch errors. Comparable in serving engineering design workflows with AI verification, though positioned at model-checking during execution rather than tender and proposal automation.
• Briq: AI-driven construction financial planning and predictive analytics. Comparable vertical SaaS approach to construction industry pain points, though specialized in financial forecasting rather than documentation and tender workflows.
• OpenSpace: AI-powered construction site capture and documentation using 360° imagery. Comparable vertical AI SaaS for AEC, though focused on visual site documentation rather than pre-construction tender automation.
• Track3D.ai: AI-based construction progress monitoring and as-built verification. Comparable vertical AI SaaS for AEC, though focused on visual site tracking and progress analytics rather than pre-construction document workflows.

Direct peers

• DocumentCrunch: AI platform that analyzes construction contracts and specifications to surface risks and key terms. Most directly comparable to Temelion's Go/No Go and contractor comparison workflows, applying AI to construction document analysis.

Broad incumbents

• Procore: Leading broad construction management platform with extensive AEC workflows. Represents the incumbent SaaS layer that could expand into pre-construction tender automation or compete with Temelion's integrated workflows.
• Autodesk Construction Cloud: Incumbent suite including Revit, BIM 360, and Construction Cloud that Temelion explicitly integrates with. The most relevant incumbent threat: could add native AI features for tender analysis and document automation.
