The winners of the Internet of Things hackathon at Amazon Development Center in Bengaluru, Akshay Joshi, Jaideep Singh, and Madhusudan Anand founded Datair Technology, whose product is Ambee.

Ambee’s models are fed with sensor data, weather patterns, traffic data, the ratio of diesel to petrol vehicles and even contextual data such as road repair, garbage burning and density of diesel generators. Armed with this information, it is able to predict street-level air pollution.

Recently actress Aishwarya Rai Bachchan, along with her mother, Vrinda KR, has joined the list of investors. The filings sourced by paper.vc show that Mrs. Bachchan has invested ₹50 Lakhs each.

Aishwarya Rai Bachan is known to invest in such pro-environmental projects. Around ten years back she had invested in the wind power projects in Maharashtra, in Dhule and Nandurbar.

Ambee, which is part of the US-based Techstars incubator, is engaging with health and fitness apps that use its data to inform customers of the best time for workouts. It is now hoping to sell the data to local authorities to take on-ground action on improving air quality.

Ambee is also in talks with an e-commerce company to sell air quality data that the firm will deploy to target customers with cosmetics, air purifiers and other related goods based on the air quality locally.
