What Cleanflow does

CleanFlow Air Technology BV ("Cleanflow") is a privately held Dutch limited company (KvK 85213063) operating from the Netherlands with a 9-person team. The firm provides indoor-climate and ventilation solutions targeted at specialized indoor environments — operating complexes and hospitals, clinics, cleanrooms, laboratories, and (to a lesser extent) offices. Its core technology stack centers on physical air-quality measurement (air volume, temperature and relative humidity, air-tightness per NEN 2686 / NEN-EN-ISO 9972:2015, CO2, and particulate matter) combined with applied knowledge of Dutch Building Decree 2012 ventilation minima, occupational-health (Arbo) standards, and GMP cleanroom requirements. The offering spans three service tiers — Consultancy (on-site inventory and analysis), Measurements (Metlingen), and Service & Maintenance — delivered as a single bundled engagement from advice through installation to recurring maintenance, with no AI/ML or software product evident.

The business model is sales-led B2B professional services. Pricing is quote-based and not publicly disclosed; customers are acquired via direct outreach, the company website (cleanflow.nl), phone, and email. Revenue is generated from per-engagement consultancy fees, measurement projects, installation work, and recurring service & maintenance contracts whose frequency is calibrated to contamination levels in each space. The customer base is segmented vertically across healthcare and controlled-environment facilities in the Netherlands, with offices positioned as a secondary vertical. Distribution is single-country, direct, and bespoke — there is no channel network, no partner ecosystem, and no self-serve digital product. The strategic narrative explicitly ties demand drivers to COVID-19 awareness, the energy crisis, and climate-neutrality commitments, framing Cleanflow as a compliance-gap closer for buildings that fail to meet minimum ventilation requirements.

Strategically, the company is in a founder-stage operating posture: no external funding, no parent or subsidiary, no M&A activity, no documented partnerships, and no disclosed leadership changes. Its five solution verticals and three service tiers together constitute the entirety of its visible product surface, and the website footer dates the business to 2022. The combination of a small team, narrow vertical focus, and heavy reliance on individual consultancy expertise points to a lifestyle/founder-led services firm rather than a venture-scale enterprise, with growth optionality dependent on expansion of the recurring-maintenance book, deepening of the office vertical, or geographic moves beyond the Netherlands — none of which are currently evidenced.

Broad incumbents

• Siemens Smart Infrastructure: Global building automation and HVAC controls provider with extensive IAQ and ventilation management offerings. Comparable as a broad incumbent whose products overlap with Cleanflow's IAQ and ventilation optimization scope.
• Royal HaskoningDHV: Dutch engineering and consultancy firm advising on buildings, healthcare facilities, and clean environments. Comparable as a Dutch incumbent that consults on the same standards-driven, healthcare/lab facility projects Cleanflow serves.
• Honeywell Building Technologies: Global incumbent offering building automation, HVAC controls, and IAQ sensing products. Comparable as a much larger player operating in the same indoor air quality and ventilation regulation space across commercial buildings.
• Johnson Controls: Global HVAC, building automation, and controls incumbent with dedicated IAQ offerings. Comparable as a broad incumbent whose portfolio overlaps with Cleanflow's regulated-environment ventilation and energy-efficiency positioning.

Direct peers

• Swegon: European indoor environment and ventilation solutions provider for hospitals, cleanrooms, and commercial buildings. Comparable because both target IAQ and energy-efficient ventilation in healthcare and controlled-environment verticals.
• Camfil: Global air filtration manufacturer and IAQ solutions provider serving cleanrooms, hospitals, and laboratories. Comparable to Cleanflow because both operate at the intersection of air quality measurement, filtration, and compliance for controlled environments.
• HOMIJ: Dutch technical installation and building services firm specializing in HVAC, electrical, and facility maintenance. Comparable because HOMIJ delivers the kind of ventilation installation, measurement, and maintenance services Cleanflow provides to Dutch healthcare and lab customers.
• Croonwolter&dros: Large Dutch technical services contractor providing HVAC, building automation, and facility maintenance. Comparable because they execute ventilation audits, installations, and service contracts across hospitals, cleanrooms, and offices in the Netherlands.
• TSI Incorporated: Manufacturer of air quality and ventilation measurement instruments (particle counters, airflow, IAQ). Comparable because Cleanflow's core measurement service line uses the same category of instrumentation TSI sells to IAQ professionals.

Others

• Veolia Environnement: Global environmental services group providing facility and building environmental management including IAQ. Comparable as an adjacent ecosystem player that bundles environmental/IAQ services into multi-site facility contracts where Cleanflow could subcontract.
