Temelion Secures €3.2M To Expand AI pre-Construction Platform

The round was led by 360Capital, joined by ISAI Build Venture, SE Ventures, and Kima Ventures.

Temelion’s platform automates repetitive tasks for building design engineers while keeping requirements, documents, and deliverables aligned. It accelerates bid/no-bid decisions, generates accurate technical documentation, and simplifies contractor evaluations. Upcoming trade-specific workflows for Mechanical (HVAC), Electrical, and Plumbing will expand its toolkit, helping engineers deliver faster, more precise, and higher-quality results.

Founded in 2025 by Jérôme Joaug, Rodolphe Héliot, and Sébastien Gilles, Temelion is driven by experienced entrepreneurs with a strong track record in scaling companies. Its mission is to free engineers from repetitive tasks, enabling faster, error-free outputs that cut costs and improve quality across the built environment.

Jérôme Joaug, Co-founder and CPO of Temelion, shared: When we first spoke with engineers, we expected resistance to AI. What we found instead was universal frustration with the hours spent crunching documents work that none of them signed up for, yet dominates their daily lives.

The fresh funding will allow Temelion to grow its engineering team, refine workflows, speed up its commercial rollout in France (targeting building engineering firms), and invest in customer onboarding, support, and integrations with industry-standard tools.
