OKLO

Oklo Inc.

A developer of small, modular nuclear power plants, Oklo builds the "Aurora Powerhouse," a compact fast-fission reactor designed to run a decade or more without refueling and to power data centers, communities, and remote sites. It was founded in 2013 by two MIT nuclear engineers, Jacob DeWitte and Caroline Cochran, and later backed by OpenAI chief Sam Altman. The company takes its name from Oklo, a region in Gabon, Africa, where nature ran its own nuclear reactors roughly two billion years ago—the only known natural fission reactors on Earth.
