Key Points
  • Real Tech Fund invests in HeteroStacks, a heterogeneous-junction power-semiconductor startup
  • Targets AI-era data-center power constraints; power chips are key to efficiency and supply
  • Signals Japanese VC steering capital to AI-infrastructure hard tech, not just applications
Analysis

Don't watch only the application layer of AI: Real Tech Fund backed power-semiconductor startup HeteroStacks, aiming at the tightening power bottleneck in AI data centers. As compute explodes, electricity and cooling become the real ceiling, and power chips set conversion efficiency. Japanese VC funneling money into this upstream hard tech is a useful signal for Taiwanese players in chip materials and equipment. With everyone chasing compute, who solves the power that feeds it?
