In a sector marked by the growing complexity of projects and regulatory pressure, technical design offices see the time chronophagous tasks accumulate. It is to this essential link in the construction chain that Temelion is addressed, a young French startup that develops an artificial intelligence platform intended to automate design engineering.
Based in Paris and Toulouse, the company intends to release engineers from repetitive operations, by allowing them to focus on the technical dimension of their profession. Automation of documentation, tenders’ analysis, regulatory compliance and generation of technical proposals are among the first cases of use already integrated. Gradually, Temelion enriches its suite of tools specializing in electricity, CVC and plumbing, in order to offer a complete environment to accelerate design and increase the accuracy of deliverables.
For its founders, the stake is not a saving time. “During our first exchanges with the engineers, we expected a certain form of resistance to AI. Instead, it is unanimous frustration in the face of hours spent processing documents that have been shared to us, a work to which no engineer had ever sucked but which nevertheless occupies a large part of their daily life. Temelion was created to free them from these tedious tasks and allow them to focus on the technical dimensions of engineering they really like, ”explains Jérôme Joau, co -founder and product director.
Rodolphe Héliot, CEO and co -founder, underlines the scope of the project: “This fundraising allows Temelion to bring together the best talents in AI and in building engineering to take up a large construction challenge, the automation of the design. We will accelerate the development of our products and their marketing, with the ambition to quickly become the privileged technological partner of our customers, capable of supporting them throughout the project cycle. »»
Founded in 2025 by Jérôme Joaug, Rodolphe Héliot and Sébastien Gilles, Temelion now announces a fundraising of 3.2 million euros in priming. The Tour was led by 360 capital, with the participation of Isai Build Venture, VEVENURES and KIMA Ventures, as well as Business Angels in the construction sector.
