What EVADIES does

EVADIES (legal name SARL EVADIES) is a privately held French environmental consulting firm founded in 2016 by Rémi Merlen and headquartered in Bouillonville, Grand Est. The company operates as an independent expert bureau focused on three integrated service lines: environmental surveillance (detecting and quantifying impacts of industrial, infrastructure, construction, and agricultural activities on air, water, soil, and the biosphere), health risk assessment (evaluating effects of environmental exposure on neighboring populations), and indoor air quality characterization for workplaces and public buildings. Its technical platform is built around a fleet of certified measurement instruments — Leckel SEQ 47/50 sequential samplers, OWEN fallout gauges, Biostation biosurveillance units, Microvol dust samplers, and meteorological stations — supplemented by atmospheric dispersion modeling delivered via a partnership with Numtech.

The company generates revenue primarily through professional services engagements (environmental impact assessments, IEM interpretations, Air Health chapters, regulatory dossier support) and, atypically for a consultancy, also rents measurement equipment and provides measurement subcontracting to other consulting firms and control offices. Pricing is quote-based per project, with multi-year contracts cited. Customer concentration lies with French industrial majors and public-sector clients — Veolia, Suez, EDF, Lafarge, Vicat, Tereos, Eurovia, CSTB, VINCI Autoroutes on the enterprise side, and DGAC, Métropole Grand Nancy, Région Grand-Est, and BRGM on the government side.

Operationally, EVADIES is a micro-firm (approximately 5 employees) deliberately built around senior expertise, with each expert averaging 20+ years of experience in environmental metrology and health risk evaluation. The business model relies on direct B2B engagement, a LinkedIn presence for visibility, and a network of complementary specialist partners (A2L Environnement, Apilab, ENCEM, Odometric). The company reinvests 1% of revenue into local environmental and societal initiatives and has made substantial recent capital investments in measurement equipment.

Broad incumbents

• Bureau Veritas: Global testing, inspection and certification (TIC) major with extensive French operations covering environmental impact assessment, air quality, and industrial compliance — directly overlaps with EVADIES' environmental surveillance and health risk evaluation services, but at vastly larger scale and broader scope.
• SGS France: Global TIC firm with French environmental services including air quality monitoring, impact assessments, and EHS compliance — competes for the same industrial and infrastructure projects that EVADIES targets.
• Apave: French TIC group with environmental and industrial hygiene offerings including air quality measurement and regulatory compliance support — comparable to EVADIES' service lines but as part of a much broader risk-management portfolio across France.
• Eurofins Environment Testing France: Major environmental laboratory network providing air, water, and soil testing services across France — comparable as the analytical backbone EVADIES routes samples to, and a potential substitute for in-house measurement services.

Direct peers

• INERIS: French public expert institute on industrial and environmental risks providing atmospheric dispersion modeling, chronic risk assessments, and methodological guidance — directly comparable technical authority in EVADIES' domains, though operating as a public research body.
• ANTEA Group (France): French environmental engineering consultancy offering air quality studies, impact assessments, and health risk evaluations for industrial and infrastructure clients — the closest direct peer to EVADIES in scope and customer profile.
• Numtech: French specialist in atmospheric modeling, odor dispersion, and air quality modeling — EVADIES' named technology partner and a comparable niche player in dispersion modeling and odor assessment for industrial sites.
• A2L Environnement: French environmental consultancy specializing in odor measurement, air quality diagnostics, and industrial emission assessments — EVADIES' partner with overlapping core services and similar client base.

Others

• BRGM (Bureau de Recherches Géologiques et Minières): French geological survey and public environmental expert — listed as an EVADIES customer and operates comparable soil, water, and environmental assessment services, but as a public agency rather than commercial consultancy.

Emerging players

• Odometric: French niche firm specializing in olfactometry and odor measurement methodology — EVADIES' partner and a comparable specialist in olfactory assessment for industrial sites.
