Weather-modification startup Rainmaker raised $100M from investors including DCVC, Upfront and Lowercarbon. CEO August Doricko explains cloud seeding — dispersing material into sub-0°C clouds so tiny droplets freeze into heavy snowflakes — and claims radar can now, for the first time, measure how much precipitation is manmade. The company plans to scale its research org toward a flywheel of atmospheric data collection and intervention.
