Senior Leadership

Ratu Mataira
Founder, CEO
The co-inventor of our key enabling technologies, Ratu founded OpenStar recognising the astronomical potential of the dipole for the future of fusion. Blending his background, a PhD in Physics and a Major in Economics, he is the driving force behind OpenStar’s growth. He has created a world-class company that understands a viable fusion future not only needs physics excellence but a bankable commercial model baked into its core.
