Arista Networks is an American networking company founded in 2004 that sells high-speed ethernet switches and routers for data centres, campus networks and increasingly artificial intelligence clusters. Its differentiator is EOS, a network operating system built on an unmodified Linux kernel with a published state database, which allows programmatic control and streaming telemetry that traditional switch software could not offer. Headquartered in Santa Clara and listed on the New York Stock Exchange, it counts the largest cloud operators among its biggest customers and has taken substantial share from incumbent switch vendors in the data centre.

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.
