Company Description

TAE Technologies is a company focused on developing commercial fusion power. It has constructed five generations of National Laboratory-scale devices and is leveraging its proprietary science to create innovations in adjacent markets, including power management, energy storage, electric mobility, and life sciences. Founded in 1998, originally as Tri Alpha Energy, the company has raised over $1.2 billion in private capital and filed more than 2,300 patents globally, with approximately 1,400 granted.

Looking forward, TAE Technologies has announced a plan to merge with Trump Media & Technology Group, which would make it one of the first publicly traded fusion companies. Following the deal's expected closure in 2026, TAE intends to begin construction on its first utility-scale fusion power plant, named Da Vinci. This project represents an acceleration of its roadmap, as the company decided to bypass a previously planned intermediate research device. The company is also expanding internationally through a joint venture with the UK Atomic Energy Authority, called TAE Beam UK, to commercialize its particle accelerator technology for use in fusion, cancer therapeutics, and other industrial applications.
