Oklo Inc.

Oklo Inc. is an American energy company developing advanced fission power plants designed to deliver clean, reliable, and affordable electricity at scale. The company’s core offering is the Aurora powerhouse, a fast-reactor power plant designed to produce roughly 15 up to 75 megawatts of electricity, aimed at customers seeking dedicated, long-lived power generation. Alongside its reactor program, Oklo is commercializing nuclear fuel recycling and fuel fabrication technology intended to convert used nuclear fuel into usable fuel for its reactors.

The company was founded in 2013 by Jacob DeWitte and Caroline Cochran and is headquartered in Santa Clara, California. Oklo became a public company in May 2024, when it listed following a business combination with AltC Acquisition Corp.; the combined entity changed its name to Oklo Inc. that month. Its common stock trades under the ticker OKLO. Co-founder Jacob DeWitte serves as Chief Executive Officer and Chairman, and co-founder Caroline DeWitte (Cochran) serves as Chief Operating Officer and Director.

Oklo positions itself as a builder of “advanced nuclear systems to deliver clean, reliable power at scale,” turning proven science into real-world infrastructure. According to the company, its reactor technology and fuel recycling work are directed at closing the nuclear fuel cycle and providing emission-free power for decades without refueling, an approach the company has described as making reactors people want.

Oklo has reached several regulatory and development milestones. The company received a Site Use Permit from the U.S. Department of Energy, demonstrated fabrication of its fuel, was awarded fuel from Idaho National Laboratory, and submitted an advanced fission license application to the U.S. regulator. It has received grant funding from U.S. government programs and has been backed by investors including Y Combinator.

Beyond reactor deployment, Oklo has expanded through investment and acquisition activity, including investments in other advanced nuclear developers and acquisitions of engineering-related firms. Its stated sector is utilities, with a focus on clean energy, deep technology, manufacturing, and climate technology. Oklo has drawn media coverage from outlets such as Popular Mechanics, Wired, Architectural Digest, POWER Magazine, and Hyperallergic, and has been the subject of a Harvard Business School case and featured in the documentary The New Fire.

Oklo describes its culture through four stated values. Collaboration means bringing diverse perspectives, listening actively, and building trust through transparency and respect across disciplines. Humility means acting for the good of the company and the world and focusing on the mission rather than personal recognition. Ownership means taking pride in the work, being proactive in finding solutions, and seeing tasks through to completion. Pathfinding means charting new ground with curiosity, courage, and creativity while navigating ambiguity.

The company states that it is assembling a team of engineers, operators, and builders who want to solve hard problems that matter and turn proven science into real-world infrastructure. It reports offering benefits including medical, dental, and vision insurance, life and disability coverage, flexible spending accounts, an employee assistance program, a wellness stipend, 401(k) matching, an HSA plan, equity where eligible, flexible PTO, one-week breaks in summer and winter, paid parental leave, a relocation stipend, and remote work opportunities where appropriate. Roles may be based at offices or project sites.
