Starmaker One

Starmaker One is the flagship venture fund of East X Ventures, a London-based deep-tech investment manager. It is the first early-stage fusion energy venture capital fund outside the United States and the first globally to partner with a government as a cornerstone investor, with the UK Department for Energy Security and Net Zero (DESNZ) committing £20M of an overall target raise of £100M–£150M. The fund invests from Seed to Series B across two thesis pillars: fusion power systems (reactor, magnet, laser, and plasma technologies, approach-agnostic) and the enabling supply chain (components, materials, and advanced manufacturing). Portfolio companies span Europe, North America, and Asia. Founders seeking investment are directed to contact the East X Ventures team directly via the firm's website.
