WaterSmart Software, a green tech startup that's frequently compared to the energy management startup OPower has closed a $900,000 round of seed financing led by Menlo Incubator and joined by Sand Hill Angels , Draper Fisher Jurvetson and Physic Ventures . The company's co-founder Peter Yolles explained the concept of the technology in an interview with TechCrunch ahead of the funding announcement: "...Most residential consumers don’t understand how much water they use and where it goes in the home. We’re trying to create a way for them to ask and answer questions like: how do I compare to my neighbors, in terms of water use? What are the two or three best things I can do in or around my own home to save water? What costs me the most money?"
