Temelion provides an artificial-intelligence platform that removes bottlenecks in pre-construction by automating repetitive tasks such as document crunching, requirements tracking, and technical documentation generation. The software synchronises requirements, documents and deliverables, helping engineering consultancies make faster bid/no-bid decisions and conduct more precise contractor evaluations. Future product extensions include trade-specific workflows for Mechanical (HVAC), Electrical and Plumbing, creating a comprehensive toolkit for building design engineers. Founded in 2025 by Jérôme Joaug, Rodolphe Héliot and Sébastien Gilles, the company is led by serial entrepreneurs with deep experience in scaling high-growth ventures. Temelion’s vision is to free engineers from mundane work so they can deliver faster, error-free outputs that reduce costs and raise quality across the built environment. The company recently secured €3.2 million in seed funding, which will finance product refinement, commercial rollout in France, customer onboarding and integrations with industry-standard tools.
