Keynote by Sunghyun Park, CEO & Co-Founder of Rebellions | RAISE Summit 2026
Seoul-based Rebellion, led by CEO Sunghyun Park, is establishing itself as a mass-production alternative to NVIDIA by delivering air-cooled AI server racks that achieve three times lower capital expenditure and superior efficiency through a custom hybrid SRAM and HBM3e architecture. Backed by strategic investors including SK Hynix and Samsung Foundry, the company's full-stack platform currently processes 14 million daily API calls for mission-critical applications at SK Telecom while prioritizing native open-source software compatibility. By optimizing for tokens per second per watt per dollar, Rebellion aims to diversify the global supply chain with a heterogeneous compute solution that scales via modular chiplets for both inference and emerging AGI workloads.
