EcoFactor is a fast growing start-up that helps homeowners reduce their energy bills. We collect thousands of data points from each home each day. We use this data to calculate heating and cooling strategies save the energy without compromising comfort, and then implement these strategies in real-time. Our optimizations reduce monthly bills, shed peak load, detect faults, and keep homeowners comfortable.

We're a smart and passionate team based in Redwood City, California. Come and help us move home energy management into the future.
