About UHoo

uHoo provides comprehensive indoor environmental quality (IEQ) monitoring solutions for both business and residential clients. The company was founded in 2014 by Dustin Jefferson S. Onghanseng and Brian Lin. The inspiration for the company stemmed from their personal experiences with asthma and allergic rhinitis, which were exacerbated by the poor indoor air quality in their dormitories while they were pursuing their MBAs at the Hong Kong University of Science and Technology. This firsthand experience motivated them to develop a solution to help people understand and manage the air they breathe.

Read full description

The company's core business revolves around its smart indoor air quality sensors and a software-as-a-service (SaaS) platform. For individual consumers, uHoo offers a smart air monitor that detects nine distinct air quality factors: temperature, humidity, carbon dioxide, carbon monoxide, nitrogen dioxide, dust (PM2.5), volatile organic compounds (VOCs), ozone, and air pressure. This device, roughly the size of a coffee mug, connects to a mobile app, providing users with real-time data, alerts, and personalized recommendations to improve their home environment. The business model for consumers is based on the one-time purchase of the device, which retails for around $329, with an optional premium subscription for more advanced features.

For the business-to-business (B2B) market, uHoo targets a wide range of sectors including property developers, healthcare, hospitality, manufacturing, and government entities. Its enterprise solution, uHoo Business, features the uHoo Aura device, which can track at least 13 and up to 16 environmental parameters. This is coupled with the uHoo Business Dashboard, a platform that allows for centralized monitoring of multiple locations, data analytics, and integration with existing building management systems (BMS) for automated control of ventilation and air conditioning. This service helps businesses enhance employee well-being, achieve green building certifications like LEED and WELL, and optimize energy consumption. The B2B revenue model consists of device sales and an annual subscription fee for access to the enterprise platform and its features.

Since its founding, uHoo has raised a total of $3.7 million over six funding rounds from investors including Wavemaker Partners, East Ventures, and Menarco Development Corporation. The company's technology is patented and provides a comprehensive view of indoor air quality, setting it apart from competitors that may only measure a few parameters. The platform is designed to be user-friendly, translating complex data into actionable insights for creating healthier and safer indoor spaces.
