EcoVent, which plans to sell a “smart thermostat” that controls a room-by-room heating and cooling system, raised almost $7 million in new investor funding, according to a June SEC filing.

The Boston Business Journal reports that the company is backed by 15 investors with a total investment of close to $10 million. Dipul Patel started the business in 2013 while completing his MBA at MIT. EcoVent works through a system of sensors, wirelessly controlled vents and a mobile app.
