What Lee Sormea does

Lee Sormea, which now operates under the trade name Lee Conseil following a January 2024 rebrand, is a privately held French engineering consultancy founded in 1998 and headquartered in Aubière, with additional offices in Lyon (Rillieux-la-Pape) and Clermont-Ferrand (Cournon-d'Auvergne). The firm specializes in mobility and traffic engineering, offering five integrated service lines: mobility strategy and traffic studies, data collection (including road counts, active modes, and Floating Car Data), all-mode traffic modeling and simulation (since 2004), acoustic engineering (measurements and modeling), and project management for complex multi-stakeholder initiatives. It serves primarily French public-sector clients — local authorities, départements, métropoles, and state agencies — alongside private industrial clients requiring traffic, site-access, and acoustic assessments. Notable engagements include restructuring departmental transport for the Département de la Loire-Atlantique, infrastructure work for SMMAG in the Grenoble metropolitan area, and displacement planning for the ZAC Gratte-Ciel development in Villeurbanne.

The company operates with a team of 25 collaborators under the leadership of Matthieu AYOT (Chef d'Entreprise), and is described as bootstrapped with no disclosed institutional investors, funding rounds, or M&A activity. Its core technology stack centers on proprietary survey-data processing software developed in-house and conventional multi-mode traffic modeling tools; it has no disclosed AI/ML capabilities, API platform, or software-as-a-service product. GTM is consultative and relationship-driven, relying on direct engagement with public and private decision-makers, supplemented by a content-marketing website, webinars (e.g., on autonomous mobility and connected roads), and industry event participation. The firm is structured as an independent professional-services business with project-based revenue and custom-quoted engagements, indicating a traditional specialist-consulting model rather than a scalable software or platform business.
