Rebellions is a South Korean semiconductor company founded in 2020 by former Wall Street quantitative engineers and IBM chip designers to build accelerators specialised for AI inference rather than training. Its ATOM processor targets efficiency per watt in data centre inference, and the follow-on REBEL design uses chiplet packaging to scale to large language model workloads. The company merged with Sapeon Korea, the AI chip unit of the SK group, to consolidate the domestic effort against foreign GPUs, becoming South Korea's first AI semiconductor unicorn and working closely with SK Telecom, KT and Samsung Foundry.
