What Riversen does

Riversen is a French engineering consultancy founded in 2017 and headquartered in Boulogne-Billancourt, operating as a wholly-owned subsidiary of Astek Group. The firm specializes in large-scale project engineering across four vertical sectors — Building (Bâtiment), Environment (Environnement), Energy & Industry (Énergie & Industrie), and City & Transport (Ville & Transport) — delivered through three activity poles covering engineering studies (Études), project management (Projet), and construction execution (Réalisation). Its core technical capabilities span BIM (Building Information Modeling), structural engineering, HVAC design, electrical engineering, and energy performance consulting, with notable specialization in highly complex and safety-critical environments including nuclear new-build, high-speed rail, metro systems, and LNG terminals.

The company's revenue model is professional services-based, priced per project scope rather than via standardized SaaS or product pricing, with no public fee disclosure. Go-to-market is enterprise field sales driven by business developers and engineering managers who recruit delivery teams and engage directly with project owners and general contractors. Marquee engagements include Hinkley Point C (EDF, UK), Grand Paris Express (Société du Grand Paris), HS2 (UK), Tour Saint-Gobain La Défense, the Dunkerque LNG terminal, Daimler/Smart's Hambach factory extension, and the CPE 140 energy performance contract for 140 Paris schools.

Riversen employs approximately 200 people (Riversiens) with an average age of 35, operates from three French offices (Paris, Lyon, Aix-en-Provence), and claims delivery presence across 13+ countries spanning Europe, Africa, Asia, and Oceania. The business inherits ISO 27001, ISO 9001, Top Employer 2026, Index Egalité Femmes-Hommes 92/100, and Handi-Accueillante certifications from the Astek parent, supporting eligibility for regulated and public-sector tenders. There are no disclosed funding rounds, no M&A activity, and no independent equity capitalization; Riversen is fully owned by Astek Group (€730M revenue, ~10,000 employees globally in 2025).
