South Korean AI chip designer Rebellions said on June 30 that it is acquiring AI inference optimization company SqueezeBits, as part of an effort to become a full-stack AI infrastructure provider rather than a chip designer alone.
The deal gives Rebellions' in-house software to sit alongside its neural processing unit (NPU) hardware, and the company aims to offer AI infrastructure that spans hardware, software optimization, and inference serving on a single platform, covering everything from receiving a request to running the model and returning a result.
As AI services move into wider commercial use, how efficiently a model runs in production is becoming as important to competitiveness as the model's raw performance, and Rebellions framed the acquisition as a way to bring that system-level capability in-house.
A deep-tech startup with global partners
SqueezeBits was founded in 2022 by researchers from Seoul National University, KAIST, and POSTECH. The company builds technology that compresses and lightens AI models, speeding them up and lowering operating costs across different hardware environments. It has built working relationships with Intel and Nvidia and has drawn investment from the venture arms of Samsung Electronics, Naver, Kakao, and Posco, according to Hankyung.
Rebellions and SqueezeBits are not new partners: the two companies have worked together since 2024 on model lightweighting technology and dedicated software for Rebellions' NPUs, and have jointly hosted events and workshops on vLLM, an open-source inference optimization framework, for Korea's developer community — work that Rebellions said helped build an NPU-based open-source AI ecosystem.
That track record gives Rebellions confidence that the two teams can produce results quickly once SqueezeBits formally joins the company, which will be structured as a comprehensive, cashless share swap. Rather than merging SqueezeBits into its existing operations, Rebellions plans to run it as an independent subsidiary.
Big picture: sovereign AI push
The acquisition comes as Seoul pursues a broader effort to build a domestic NPU ecosystem. Rebellions was named in March 2026 as the first direct investment target of Korea's National Growth Fund, a role the company has tied to the government's ambition to cultivate a domestic AI chip champion.
Rebellions described the SqueezeBits deal as an extension of that effort beyond hardware, into building out the wider AI industry ecosystem and what it called sovereign AI infrastructure.
It is Rebellions' first acquisition since its 2024 merger with Sapeon Korea, which combined two domestic AI chip companies. Rebellions said it plans to keep pursuing combinations of this kind as it builds scale and competitiveness globally.
"We believe Korea's AI infrastructure ecosystem opens up new possibilities when technical capability and exceptional talent come together across the boundaries of individual companies," said Rebellions CEO Sunghyun Park.
SqueezeBits CEO Hyungjun Kim said his company's inference optimization technology will expand the reach of the Rebellions NPU ecosystem and help customers run AI services on Rebellions NPUs more economically.
