Rebellions Raises $400 Million, Valued at $2.3 Billion Ahead of IPO

The South Korean AI chip startup, Rebellions, has recently succeeded in raising $400 million in a funding round. This round, which precedes an anticipated IPO later this year, was led by Mirae Asset Financial Group and the Korea National Growth Fund. This influx of capital coincides with the company's aggressive expansion efforts, as it announced its intention to increase its presence not only in Asia but also in the Middle East and the United States.

Founded in 2020, Rebellions specializes in the development and design of AI chips while outsourcing their manufacturing. The startup's chips are specifically designed for inference, the computation necessary for AI models to respond to user queries. Inference has gained importance as large language models (LLMs) have matured and begun to be deployed commercially at scale.

In 2024, Rebellions closed a $124 million Series B funding round. Then, in November, the company raised an additional $250 million in its Series C. To date, the total amount raised by Rebellions stands at $850 million, with $650 million raised in the last six months. The current valuation of the startup is approximately $2.34 billion, as stated by the company on Monday.

In addition to this funding round, Rebellions also announced the launch of two new products: RebelRack and RebelPOD. The RebelPOD is described as a production-ready inference computing unit, while the RebelRack integrates multiple racks into a scalable cluster designed for large-scale AI deployment, according to the company's specifications.

In a conversation with TechCrunch, Rebellions' Chief Commercial Officer, Marshall Choy, who leads the company's global expansion efforts, stated that Rebellions has recently established entities in the United States, Japan, Saudi Arabia, and Taiwan. Choy mentioned that the company is building its ecosystem of technology partners in the U.S., where it plans to attract cloud providers, government agencies, telecommunications operators, and Neoclouds. However, he declined to comment on the IPO timeline.

"AI is now measured by its ability to operate in the real world at scale, under energy constraints, and with a clear economic return," said Sunghyun Park, co-founder and CEO of Rebellions. "This shifts the focus towards inference infrastructure and the software that makes this infrastructure usable."

Rebellions is part of a new generation of chip startups looking to challenge NVIDIA's once-uncontested dominance in the chip industry. As this dominance begins to wane, other major tech companies like AWS, Meta, and Google — along with this new generation of startups — are also seeking to produce their own chips.
