Temelion

AI copilot for bid/no-bid, technical proposals, and contractor bid comparison

Temelion is an AI copilot for building engineering firms (bureaux d'etudes techniques) that reads tender documents to score bid/no-bid viability, auto-drafts technical proposals from a firm's own bid history, and produces side-by-side contractor bid comparisons with flagged inconsistencies. An "Electric Pack" workflow also synchronizes electrical engineering deliverables with HVAC and environmental data to catch cross-specialty conflicts.

€3.2M (seed, announced September 2025; led by 360 Capital with ISAI Build Venture, SE Ventures, and Kima Ventures) raised Early Stage
Founded 2025 · In beta with "major engineering and architecture firms" in France as of the September 2025 seed announcement; specific firm names and customer count not publicly disclosed

WHY IT EXISTS

Why This Tool Exists

The Problem

Building engineering teams (bureaux d'etudes techniques) spend hours manually screening dense tender documents for bid/no-bid decisions, assembling technical proposals from scratch, and comparing contractor pricing schedules line by line in spreadsheets — work that eats into already-thin design margins and slows bid turnaround.

The Solution

Temelion's AI reads tender documents, contracts, and technical specs to score bid/no-bid viability against required skills and team workload, auto-drafts technical proposal sections from a firm's own proposal history, and generates side-by-side contractor bid comparisons with flagged pricing and technical inconsistencies — with human review built into each workflow before submission.

Exactly what this tool uses and how

Input
What it needs
Required: Tender/bid documents, Technical specifications
Optional: Contractor pricing schedules and technical proposals, Bills of Quantities, Past technical proposals / project history, Custom Go/No-Go evaluation grid
Formats: PDF, Word (.docx), Email, ZIP
Output
What you get
Format: Workflow-specific reports reviewed in-app before download (bid/no-bid analysis, comparison tables, auto-drafted proposals); exact download file formats not publicly specified
Fields: Bid/no-bid recommendation with risk flags, Tender/contract summary, Contractor bid comparison table, Flagged technical and pricing inconsistencies across bids, Auto-drafted technical proposal sections, Electrical deliverable conflict flags vs. HVAC/Environment data
Algorithm
How it works
Model: Proprietary "vertically trained agents" for construction/engineering workflows (underlying LLM not publicly disclosed)
Accuracy: Vendor claims (not independently verified): 10x faster tender analysis, 1.7x faster bid/no-bid decisions, -90% contractor-comparison process time, +25% projects responded to, +20% win rate
Privacy
How your data is protected
Retention: Vendor blog states it will "clearly communicate how long Temelion retains project data" but does not publish a specific retention period
Training: Vendor blog states data may be used "to improve models or service features" and commits to disclosing this to clients, without a definitive yes/no on training its own models on customer data; vendor states it scans, labels, and blocks sensitive information before sharing with third-party AI tools
Compliance: Not publicly specified (no SOC 2, ISO 27001, or other compliance certification found on official sources)
API
Integration
Endpoint: Not publicly available
Method: Not applicable
