WeavAir

WeavAir provides an enterprise software platform combined with proprietary data acquisition hardware for monitoring air and environmental conditions in buildings and air distribution systems. Its multi-sensor IoT devices measure 20 metrics spanning air quality, HVAC performance, carbon emissions, predictive maintenance and occupancy or people flow, which the company states are captured in real time at 95% accuracy. The accompanying software displays current conditions — air quality, gases and particulates present, filtration effectiveness, heating, cooling and ventilation efficiency, occupancy and a health and safety index — and applies predictive algorithms to detect, diagnose and forecast faults before they escalate, including direct integration with existing ventilation systems to enable automated HVAC operation.

The company positions the offering as "Safety as a Service" and, more recently, as "Sustainability as a Service": a digital platform for direct measurement, reporting and verification of greenhouse gas emissions intended for ESG investment, energy transition implementation, financing and insurance use cases. Data sources are modular and continuous, combining networks of satellites, drones and IoT devices to track greenhouse gas emissions, energy efficiency, maintenance, operations and climate risk parameters. WeavAir states its predictive decision support system is trained on more than 10 years of data, diagnoses and prevents air hazards 200 times faster than comparable solutions, and does not require system recalibration.

Reported customer outcomes include savings of over US$300,000 per installation per year, a payback period of under two years, 30% reductions in operation and maintenance costs and up to 60% energy savings, alongside reduced downtime and lower legal and insurance risk.

Founding story

Co-founder and CEO Natalia Mykhaylova has a background in engineering, chemistry and design. During her PhD she developed low-cost sensor devices and adaptable wireless networks capable of rapidly reporting levels of common air pollutants; these devices were deployed at Toronto's 2015 Pan Am Games to monitor the Air Quality Health Index so athletes with allergies could adjust training times and locations. Through consulting and sensor development work she found that over 75% of ventilation systems were functioning poorly and that existing monitoring technologies were either too expensive or insufficiently accurate and reliable. Mykhaylova, who has founded companies in Canada, South Korea and Hong Kong and worked in business development across Taiwan, Chile, the Netherlands and Austria, has said customer interviews with real estate and HVAC operators confirmed the market need and led her to assemble a team and start the company.

Business model

WeavAir sells recurring subscriptions to its hardware and analytics platform. One subscription covers IoT multi-sensor devices plus predictive AI software for asset owners and operators; a second covers data-driven predictive software and API integrations aimed at contractors, insurance companies and consulting firms.

Recurring subscription revenue for sensors and analytics, across two principal plans: an IoT device plus predictive AI software subscription for asset owners and operators, and a software and API-integration subscription for contractors, insurers and consultancies.

Traction

WeavAir has run pilots and deployments in the U.S., Belgium, China, Taiwan, Japan, the Philippines, Spain, Portugal and Chile, including with Seoul Metro and the Ritz Carlton in Singapore. The company reports customer savings exceeding US$300,000 per installation per year with ROI under two years, and has said it targets $80M+ annual recurring revenue within five years. Its website cites more than 20 awards.

Latest developments

In November 2024 WeavAir was selected for the fourth cohort of the CASSINI Business Accelerator, a European Commission programme running from November 2024 to April 2025, where it was described as serving financial institutions and fund managers assessing ESG performance using satellite imagery, predictive AI models and decision support systems. Its website presents a "Sustainability as a Service" platform for measurement, reporting and verification of greenhouse gas emissions.
