Rebellions Tech Stack

AI inference chips and full-stack systems built on NPUs

Semiconductor Manufacturing Seoul 201–500 employees Founded 2020 Privately Held
rebellions.ai LinkedIn

Rebellions designs NPU-based AI inference hardware with a software stack supporting PyTorch, aimed at enterprise and sovereign AI deployments. Its stack is heavy on server-management and interconnect tech (IPMI, Redfish, RDMA, InfiniBand, NCCL), and it is adopting Embedded Linux, Yocto and PREEMPT_RT, which points to a firmware migration off RTOS as it moves from chips toward rack-scale systems. Hiring skews toward senior engineering, with a smaller sales push.
