Company Overview

Clairco is the trade name of Aliferous Technologies Pvt Ltd, a Bengaluru based company that develops IoT and AI enabled systems for indoor air quality management and HVAC energy optimisation in commercial buildings. It was founded in 2018 by Aayush Jha, who serves as chief executive, and Udayan Banerjee, who serves as chief product officer. The name is short for Clean Air Company.

The company began by retrofitting existing air conditioning and ventilation units with air purification capability, offered as a monthly subscription so that customers avoid upfront equipment spending. Over time its focus widened to include energy optimisation, using occupancy and air quality data to adjust how heating, ventilation and cooling systems operate. It now describes its offering as clean air and energy efficiency as a service.

Its core technologies combine networked environmental sensors, thermal and people counting sensors, a proprietary AI engine, a web dashboard and filters designed for low resistance to airflow. The company describes its air filtration and energy optimisation technologies as patented.

Clairco states a vision of helping transform buildings into net-zero emission structures through IoT and AI. Its work is directed at owners and operators of commercial properties, and its chief executive has contributed to HVAC industry publications and webinars on efficiency and air quality.

Why These SDGs Matter

Good health and well-being is directly relevant because the company monitors and filters pollutants such as fine particulates and volatile organic compounds inside occupied buildings, where people spend much of their working day.

Affordable and clean energy applies because its occupancy based HVAC control is designed to lower cooling energy use, which is an efficiency outcome under this goal.

Industry, innovation and infrastructure fits because the company upgrades existing building systems with patented filtration and AI driven controls, improving the resource efficiency of infrastructure already in use.

Sustainable cities and communities is relevant to the air quality element of urban life, since indoor air conditions in commercial buildings are shaped by the polluted outdoor air of Indian cities.

Climate action is supported because reducing HVAC electricity consumption lowers the emissions associated with operating commercial buildings, which is the stated purpose behind the company’s decarbonisation vision.

Business Challenges Solved
  • High HVAC energy consumption in commercial buildings
  • Cooling and ventilation running without regard to actual room occupancy
  • Poor indoor air quality in air conditioned offices and retail spaces
  • Upfront capital cost barriers to adopting air purification
  • Need to improve air quality without replacing existing HVAC equipment
  • Lack of continuous, measurable indoor air quality data
  • Unplanned filter clogging and reactive filter replacement
Approach & Methodology

Clairco’s delivery model rests on three layers: sensing, analytics and retrofit hardware, sold under a subscription arrangement.

At the sensing layer, sensiAIR monitors measure particulate matter, carbon dioxide, carbon monoxide, total volatile organic compounds, temperature and humidity in real time. clairPOINT thermal occupancy sensors detect movement and heat patterns without cameras or personal data, and clairCOUNT sensors record foot traffic. Together they give zone level views of both air quality and space use.

At the analytics layer, readings feed a proprietary AI engine and a web dashboard. The company states that the engine produces forecasts as well as current insights and uses occupancy and heat load information to adjust HVAC operation. Air quality data is also used to predict filter condition, so cleaning or replacement can be scheduled before performance drops. A 2025 industry article by the chief executive also describes integration with building management systems.

At the hardware layer, low pressure drop filters are retrofitted into existing air handling units so that installed equipment stays in use and airflow is not restricted. The company describes its NanoClair filters as nano-tech air purification.

Commercially, the offering is structured as a service. Customers pay a recurring fee, and the company has described air quality commitments tied to service level agreements agreed with each client. It also states that savings from its energy optimisation service are intended to offset the cost of air quality management.

Market Position

Clairco operates in the commercial building technology segment, where indoor air quality management and HVAC energy optimisation are increasingly treated together. Its customers are owners and operators of commercial real estate, including office campuses and shopping centres, and it sells to businesses rather than individual consumers.

Its positioning rests on retrofit compatibility and a subscription model that avoids upfront capital spending. In its Nasscom Emerge 50 entry, the company describes the pairing of nano-tech filtration with AI driven IoT energy savings as distinct from conventional integrators. Tracxn classifies Clairco as a seed stage company, and CB Insights lists building automation firm 75F among comparable companies.

Procurement Considerations
  • Confirm compatibility with your air handling units, including filter frame sizes and available static pressure
  • Ask for a baseline energy audit and an agreed measurement and verification method for any energy savings
  • Review service level terms: air quality metrics, thresholds, sensor placement and remedies
  • Clarify subscription pricing, contract term, and who handles filter replacement and disposal
  • Request test reports and compliance documents for sensors and filters
  • Check dashboard access, building management system integration and how occupancy data is handled
  • Confirm on-site service coverage and response times for each of your locations
  • Request references from comparable commercial installations
Funding, Recognition & Ecosystem
  • Angel funding of Rs 4.2 crore announced in March 2021, led by Anicut Angel Fund with participation from Max Group and AngelList
  • Selected for the 2022 REACH Australia scale-up program run by Second Century Ventures, the strategic investment arm of the National Association of Realtors
  • Winner of the Nasscom Emerge 50 awards in 2023, recognised for sustainability
Natnavi Analysis

HVAC systems are a major source of energy use in commercial buildings, and indoor air quality is often procured separately from them. Clairco matters because it treats the two together, which is relevant in Indian cities where outdoor air pollution and cooling demand are both high.

Its main strengths are a retrofit approach that works with existing equipment and a service model that moves cost from capital budgets to operating budgets. Selection for the Nasscom Emerge 50 awards in 2023 and for the 2022 REACH Australia program indicates external review of its technology and business model at an early stage. Its sustainability contribution lies in reducing HVAC energy demand and improving indoor conditions in buildings that already exist, which is where much near term decarbonisation potential sits.

Buyers should note that outcomes under performance linked contracts depend on baselines, measurement design and building conditions, so contract terms deserve careful attention. Clairco is a startup with a compact team, and procurement teams with many sites may wish to confirm delivery capacity through references from comparable installations.
