# Temelion: AI-Powered Pre-Construction Engineering
Temelion is an AI platform that automates repetitive workflows for building design engineers, enabling them to generate technical documentation, manage project requirements, and streamline pre-construction deliverables with greater speed and accuracy[1][2]. The company serves engineering consultancies and design firms during the pre-construction phase, addressing a critical pain point: engineers spend excessive hours on document-heavy, repetitive tasks that distract from higher-value design work[2].
Founded in 2025 by Jérôme Joaug (Chief Product Officer), Rodolphe Héliot (CEO), and Sébastien Gilles (Chief Technology Officer), Temelion closed a €3.2 million seed round in September 2025 led by 360Capital, with participation from ISAI Build Venture, SE Ventures, and Kima Ventures[2]. The company is based at Station F in Paris with an additional office in Toulouse[1]. The founding team comprises serial entrepreneurs with decades of experience in high-growth companies and multiple successful exits, bringing deep expertise in both technology and the built environment[1][2].
Temelion operates at the intersection of construction technology (ConTech) and enterprise AI automation, riding two powerful trends: the digitalization of traditionally analog construction processes and the deployment of AI to eliminate knowledge-worker drudgery. The timing is particularly relevant as engineering firms face labor shortages and pressure to deliver projects faster while maintaining quality—problems that automation directly addresses[2].
The company's focus on pre-construction workflows targets a less-saturated segment of ConTech compared to on-site project management tools, positioning it as a specialized solution for a specific but high-value pain point. By automating the upstream engineering phase, Temelion influences how quickly and accurately projects move from design to execution, with downstream implications for construction timelines and costs[1][2].
Temelion is well-positioned to capture market share among French engineering consultancies in the near term, with the €3.2 million seed round explicitly earmarked for commercial expansion in France and product refinement across trade-specific workflows[2]. The company's next phase will likely depend on successful integrations with industry-standard tools and demonstrated ROI metrics that resonate with design firm economics.
The broader opportunity extends beyond France: as engineering firms globally grapple with the same document-heavy bottlenecks, Temelion's playbook could scale internationally. Success will hinge on whether the platform can maintain accuracy and compliance—critical in regulated construction environments—while genuinely freeing engineers from repetitive work. If executed well, Temelion could become a foundational tool in the pre-construction phase, much as project management software became essential on-site.
