Copper, led by CEO Sam Calisch, is a Berkeley, CA-based appliances company focused on improving electrification. Its first product is a battery-equipped induction stove that plugs into a regular 120V outlet. The stove enables cooks to upgrade from gas to induction without costly, complex electrical upgrades. The company raised $28M in funding. Copper intends to use the funds to continue to scale its technology platform into additional products. The round was led by Prelude Ventures and included participation from Building Ventures, Voyager, Collaborative Fund, Climactic, Designer Fund, Necessary Ventures, Leap Forward Ventures and Climate Capital. Channing St. Copper’s core product is an Energy Storage Enabled (ESE) induction stove that embeds a modest battery into the appliance to deliver high-performance induction cooking on a normal (120V) outlet, avoiding 240V wiring. The stove includes load-shifting capabilities designed to work with power utilities and to create a network of energy-storage-enabled appliances that plug into standard outlets. Embedding batteries into appliances is intended to eliminate permitting, wiring complexity, and labor costs associated with whole-home battery installs, and to lower the installed cost and installation barriers compared with systems like the Tesla Powerwall. The company positions the product as a fast, cheap pathway to retire gas ranges (the article cites 45 million gas ranges in use) and to reduce greenhouse gas emissions while improving public health and safety. Channing St. Copper plans to expand its offering toward whole-home electrification with a suite of ESE appliances including hot water heaters, mini-split/heat-pump air conditioners, and clothes dryers. The LinkedIn post congratulates Eric Wilhelm, Sam Calisch, and the Channing St. Copper team for the milestone.
