What dnota does
dnota is a privately held Spanish environmental-technology company founded in 2010 and headquartered in Tres Cantos, Madrid, that designs, distributes and services air quality monitoring solutions. The portfolio combines a proprietary IoT sensor platform — the Bettair line, certified by AIRLAB in 2023 as the world's most accurate air quality sensor — with a full catalog of reference-grade gas and particulate analyzers (NO/NO2/NOx, O3, CO, CO2, SO2, NH3, H2S, BTEX, PM1/PM2.5/PM10, ultrafine and black carbon), particle samplers, portable instruments, tunnel instrumentation, meteorological stations, mobile monitoring units and complete emissions measurement systems (CEMS). dnota also distributes equipment from Thermo Scientific, Fuji Electric, MKS Instruments and Advanced Energy under OEM agreements, and runs an ENAC-accredited ISO/IEC 17025 calibration laboratory for traceability and regulatory-grade measurement.
The company monetizes through four interlocking streams: hardware sales (its own Bettair nodes and third-party analyzers), professional services (turnkey project implementation, multi-brand maintenance, calibration, training, consulting), recurring software/SaaS revenue (cloud Bettair platform, CEMS and immission data management, API access), and usage-based rentals (mobile units and IoT nodes for campaigns). The SaaS/API surface and cloud-based data visualization enable integration with smart city and decision-support systems. Go-to-market is hybrid: direct sales for Spanish and key European government accounts, complemented by an international distributor network covering 70+ countries with named partners in Mexico (Persis), UK (Enviro Technology), Canada (MFE/ES Canada), USA (W5 Engineering), Colombia (CINTEL), China, Greece, Turkey, France and Portugal, plus a wholly-owned Florida subsidiary (dnota airquality Corp) established January 2024.
dnota primarily serves government and municipal authorities (city councils, regional governments, airport and metro-meteorological agencies) implementing EU air quality directives and Low Emission Zones; secondary verticals include industrial and waste-management facilities (e.g., Claystone Waste landfill) and infrastructure operators (e.g., 2026 Milano-Cortina Winter Olympics construction monitoring). Named reference customers include NYC Department of Environmental Protection, Gobierno de las Islas Baleares, Ayuntamiento de Alcobendas, IFEMA/Madrid, Aeropuerto de El Prat (Barcelona) and METEOCAT. The Microbial sub-brand adds food and water microbiology (rapid Salmonella detection kits) as an adjacent offering. The company has 51-100 employees, no external funding rounds disclosed, and CEO Óscar Navarro Cabrera received the 2025 La Razón Executive of the Year award.
