What toumi ag does

toumi ag (legal name: 2me toumi AG) is a Swiss independent building pollutant diagnostics company founded in 2014 by Jonathan Toumi and headquartered in Biel/Bienne, Switzerland. The firm specializes in the identification, measurement, and management of hazardous substances in buildings, offering five core service lines: Bauschadstoffuntersuchung (building contaminant investigation for asbestos, PCB, PAK, heavy metals, formaldehyde, mold, wood preservatives); Raumluftmessung (indoor air quality measurement per ISO 16000 standards); Radonmessung (radon measurement using accredited dosimeters, recognized by BAG as an official measurement point); Fachbauleitung (specialist construction management for remediation projects including cost estimation, tendering, on-site monitoring, and zone clearance per VDI 3492); and Geologie & Altlasten (contaminated sites consulting per AltlV).

The business operates on a project-based professional services model with quote-based service pricing for diagnostic and construction management engagements, and publicly listed CHF-denominated course fees (CHF 450 to CHF 1,950 per participant) for its training programs. Go-to-market is hybrid: direct field sales target enterprise clients including pension funds, real estate administrators, architects, and institutional property owners; an online Offertenrechner (quote calculator) supports self-service lead capture from private customers; and a SUVA-recognized, EKAS-certified training academy at the Biel headquarters delivers continuing education courses including Asbestos Basic, Specialist Asbestos Remediation EKAS 6503, KOPAS, and Certified Building Contaminant Diagnostics.

The company maintains three distinct customer segments: business customers (multi-family building owners, real estate administrators, pension funds), private customers (homeowners and condominium owners), and Weiterbildung (professional training for construction workers, safety officers, and diagnostics professionals). Notable enterprise customers include BKW (nuclear power plant decommissioning support), SBB (Swiss Federal Railways), Swatch Group, and Stadt Biel. As of 2025, the firm employed 10 people, having grown organically from 4 employees in 2016, with no disclosed external funding.

Broad incumbents

• Bureau Veritas: Global TIC (testing, inspection, certification) incumbent offering building-related environmental and asbestos services across Europe. Competitor for larger enterprise and government contracts, though not specialized in Swiss regulatory nuances.
• SGS SA: Geneva-headquartered global testing, inspection, and certification giant with a building sciences and environmental services practice. Provides overlapping inspection, testing, and certification services including indoor air quality and asbestos surveys, but as part of a much broader portfolio.
• Arcadis Switzerland: Global design and consultancy with environmental and contaminated land services in Switzerland, including building-related environmental due diligence and remediation advisory. Larger, broader, but serves overlapping enterprise and government clients.
• TÜV SÜD Schweiz AG: Global TIC firm with a Swiss presence offering building inspections, environmental testing, and certification services. Overlaps with toumi's diagnostic and Fachbauleitung offerings for enterprise and government clients.
• Eurofins Environment Testing Switzerland: Eurofins' Swiss environmental testing arm provides accredited laboratory analysis for asbestos, mold, indoor air, and contaminated site samples. Comparable laboratory/analytical layer behind toumi's diagnostic offering.
