Realta Fusion raised a $36 million Series A round to bring its fusion technology closer to commercialization, the company announced today.

According to a release, the round was led by Future Ventures with participation from Mayfield, GSBackers, SiteGround, Avila VC and others. Existing investors such as WARF also participated.

“This funding allows us to validate our plasma simulations using real-world experimental data, bringing us dramatically closer to making fusion energy real,” Realta Fusion CEO Kieran Furlong said in a statement. “From there, we will design a prototype fusion device that is as de-risked as you can get it, before we actually go build it. We aim to have it operating by 2028.”

The company plans to use the funding to advance the physics of the experimental magnetic mirror fusion device currently operating at the University of Wisconsin and support the engineering and design of their own prototype CoSMo fusion energy system.
