Global AI agent startup Rainer said on Thursday it will pursue an AI full-stack solution business with Rebellions by combining AI agent technology with neural processing unit (NPU)-based infrastructure.

Rainer and Rebellions are also participating together in an SK Telecom consortium for the Ministry of Science and ICT’s project to develop a homegrown AI foundation model. The two companies will sign a memorandum of understanding and expand existing technical cooperation into the commercialization stage for an AI full-stack solution business.

The companies will seek ways to cut service operating costs by linking homegrown NPUs with AI agents, moving away from an AI infrastructure structure centered on foreign graphics processing units (GPUs). They also plan to offer solutions for public agencies, local governments and private companies that can address data sovereignty and security requirements.

They will also pursue joint business in global markets. Rainer has secured 13 million users in more than 220 countries worldwide. It is also supplying an AI search engine to the platform of HUMAIN, an AI company under Saudi Arabia’s Public Investment Fund (PIF).

Rebellions is expanding its AI semiconductor business in overseas markets including the United States, Japan and the Middle East. The companies plan to cooperate across global business efforts, including finding partners, discussing technology and winning orders, using their respective overseas networks.

Rebellions CEO Sung-hyun Park (박성현) said, "This cooperation is meaningful in that it achieves technological self-reliance through to the actual service stage with a full-stack solution," adding, "We will complete a competitive full-stack solution and deliver results in major global markets."

Rainer CEO Jin-woo Kim (김진우) said, "If Rebellions’ high-efficiency NPU is added to Rainer’s technology, we can present a solution to the global market that has both performance and cost competitiveness," adding, "We will prove the competitiveness of K-AI in global markets such as the Middle East, beyond Korea."
