What Dervenn does

Dervenn is a French ecological engineering firm founded in 2002 in Betton (Bretagne) that operates as a tri-divisional "communauté d'entreprises" delivering biodiversity services to public-sector and private-sector clients in the Grand Ouest and at national level for selected engagements. Its three wholly-owned units are Dervenn Conseils & Ingénierie (DCI) — environmental studies bureau covering regulatory ecological assessments, naturalist expertise, AMO/MOE environmental assistance, water management and biodiversity strategy; Dervenn Compensation Écologique (DCE, founded 2017) — operator of ecological compensation projects covering site search, land securing, measure implementation and ORE monitoring under the French ERC sequence; and Dervenn Travaux & Aménagements (DTA) — field works including natural-space management, ripisylve/hydromorphological restoration, zero-phyto infrastructure landscaping and eco-landscaping. The stack rests on field-naturalist protocols (IPA, IKA, transects, quadrats, SM3 Bats, photographic/video trapping, CARHYCE, IBGN) supported by internal GIS.

The company monetizes these capabilities through project-based professional-services contracts priced on engagement scope, plus a newer Qualiopi-certified training line publicly priced at €850 HT per day per participant. Dervenn targets two primary segments — local/regional public authorities (departments, communes, intermunicipalities, PNRs) and private operators in energy transmission (RTE), construction (Eiffage), mining/materials (Imerys), retail (Intermarché) and renewables (VSB). Named customer logos and the activity footprint (423 projects in 2025, including 62 works projects, with a stated 92% client recommendation rate) indicate a mature commercial book. Dervenn holds Qualiopi, QualiPaysage "Génie écologique," UPGE/UNEP memberships, "Entreprise engagée pour la nature" recognition, and statutory Entreprise à Mission status (2021) anchoring its positioning in the French ecological infrastructure and biodiversity-compliance market. GTM is sales-led through three regional offices (Betton, Saint-Herblain, Péaule) plus trade events (Enviropro, Pollutec), content marketing, and professional social channels. No external funding, M&A, or listed capital structure has been disclosed.
