Three Cal Poly engineers built a clip-on sensor that reads the meter you already have. It cut the average home's water use 14% - and turned drought guilt into a phone notification.
Ceres AI (formerly Ceres Imaging) is an Oakland-based agtech company that flies fixed-wing aircraft over farmland with custom-built spectral sensors, then uses machine learning to turn the resulting imagery into plant-level insight on water, nutrients and crop stress. Founded in 2014 during California's drought, the company now serves growers, agribusinesses, lenders and insurers across four continents.
