Founder Xu Min
Country: China | Funding: $100M (+)
Founded: 2025
SunUp Fusion is constructing its first-generation experimental device, compact high-field tokamak codenamed "Morning Light". The startup is pursuing a differentiated technological path centered on a Deuterium-Helium-3 (D-He3) fuel cycle. Its compact D-He3 power plants are designed for flexible deployment near urban centers or data hubs. This strategy would allow them to work in tandem with larger, remote D-T facilities to form an integrated and versatile energy grid.
