Ranulfo Allen

Ranulfo (Randy) Allen is the co-founder and CEO of Still Bright, a New Jersey deep-tech startup using a vanadium-based electrochemical process to pull refined copper out of ore - and out of mine waste - at room temperature and pressure, no smelter required. A Princeton-trained chemical engineer with a Stanford PhD and a Dartmouth MBA, Allen spent years on the other side of the table as a venture investor and startup mentor before deciding to build the thing himself. Still Bright raised an $18.7M seed in 2025 led by Material Impact and Breakthrough Energy Ventures, betting that the looming copper shortage is solvable if you stop burning rock and start running electricity through it.
