Requiem

What Requiem does

Requiem Désinfection is a French specialist biohazard cleaning company headquartered in Feyzin (Auvergne-Rhône-Alpes) and founded in 2016 by brothers Christophe and Emmanuel Mercier. The company consolidates three decades of cumulative field experience accumulated through the founders' earlier venture Vita Environnement (founded 2003), positioning itself as a pioneer of the post-mortem cleaning profession in France and serving as the primary academic case study documenting the emergence of this trade. Its service portfolio centers on (i) post-mortem cleaning and disinfection of residences following deaths, (ii) clearance and remediation of housing affected by Diogenes, Noé, and Korsakoff syndromes, and (iii) pest control and elimination — including thermal bedbug treatment delivered through adjacent subsidiary CTT Désinsectisation. Supporting services include dead animal collection, pigeon droppings cleanup and deterrence, post-squat restoration, COVID-19 disinfection, building clearance, and housing preparation for re-occupancy.

Delivery is grounded in proprietary methodology: a Certibiocide-certified biohazard protocol stack built around ozonation systems, enzymatic misting for odor elimination, thermal pest treatments, and comprehensive PPE for field technicians. The founders authored a "Diagnostic Social" (social diagnostic tool) used before each engagement to assess occupant context, housing condition, infestation severity, multi-party task distribution, and material needs, and Christophe Mercier co-developed pioneering structured bedbug protocols with entomologist Cédric Thenoz. Operational protocols ensure DASRI-compliant biological waste disposal, and a complete intervention report is delivered to clients for administrative, insurance, or succession use — a documented requirement for the company's institutional buyer base.

Revenue is generated exclusively through professional-services fees, priced on a quote basis after a free on-site evaluation with no standardized packages. Average intervention tickets for Diogenes syndrome clearance run €2,000–€5,000 (≈€3,500 typical), with per-room rates starting at €400–€600 and an average of approximately €100/m² for specialized cleaning. GTM is sales-led and inbound-driven through a free 24/7 phone line (0.800.948.118), website contact, SEO-optimized regional landing pages, and referral partnerships with funeral homes, notaries, social landlords (HLM offices), CCAS, guardianship services, and charitable networks (France Alzheimer, Secours Catholique, Les Petits Frères des Pauvres). The company is bootstrapped and founder-owned with no external venture funding disclosed, operating across three French regions: Auvergne-Rhône-Alpes, Auvergne, and Provence-Alpes-Côte d'Azur.

Broad incumbents

• ServiceMaster Restore: Large North American restoration and specialist-cleaning franchise network covering trauma, biohazard and post-incident remediation. Closest international analog to Requiem's post-mortem and extreme-cleaning offering, but US-focused and broader in scope.
• Ecolab: Global leader in water, hygiene and infection-prevention solutions supplying biocides, sanitizers and disinfection protocols to institutional customers. Comparable in the chemistry/protocol layer used by Requiem but at vastly greater scale and as a supplier rather than service provider.
• Paul Davis Restoration: North American franchise network for property damage restoration and specialty cleaning, including biohazard and contents cleanup. Comparable as a restoration/specialty-cleaning peer with a franchise model Requiem could emulate to scale nationally.
• Stericycle: US-listed medical-waste and biohazard services company handling regulated waste disposal (DASRI equivalent) at industrial scale. Comparable on the hazardous biological waste handling side that Requiem performs for post-mortem interventions.
• Anticimex: European pest-control incumbent with significant French operations (acquired several local players). Comparable on the désinsectisation/dératisation side and on commercial pest contracts, but does not specialize in post-mortem or Diogenes interventions.
• Rentokil Initial: Global hygiene and pest-control group operating in France through Rentokil Pest Control and Initial Hygiene. Overlaps directly with Requiem's pest-control and disinfection services but as part of a broad commercial/industrial portfolio rather than a trauma-cleaning specialist.
• Orkin: One of the largest pest-control operators globally with presence across multiple European markets. Comparable on désinsectisation/dératisation work and on recurring commercial pest contracts, though not focused on biohazard or post-mortem services.

Regional players

• Aftermath Inc. US-based biohazard remediation and trauma-cleaning franchise providing post-death, crime-scene and hoarding cleanup. Directly comparable service offering to Requiem but operating in North America rather than France.
