Mark White manages Future Planet Capital's fusion investment area, backing companies like Tokamak Energy while also looking at the control systems, materials, photonics, and magnet technologies that fusion research produces along the way. He often gets involved before a company even exists, drawing on his experience rebuilding NESTA's investment operations into one of the UK's most active tech seed investors and managing science assets tied to public research bodies like Culham Centre for Fusion Energy and Porton Down.
