What's the endgame? Founded in 2022 by KAIST professor Kim Min-soo, GraphAI builds Akashic DB, an AI-native engine that merges graph, vector, and relational databases into one. The design lets AI query different data types in a single request, so it can grasp both company data and business context at once.
Companies typically run separate databases for structured records, unstructured files, and relationship data — a setup that complicates integration and operations. GraphAI's pitch is to collapse that into a single engine.
The proof points: The company says Akashic DB ran up to 142 times faster than existing graph databases on the LDBC SNB benchmark. Its hybrid retrieval-augmented generation (RAG) technology, developed with KAIST, improved answer accuracy by up to 78% over standard RAG, with results presented at ACM SIGMOD 2026.
Where it's deployed: GraphAI runs projects and pilots with clients including the Agency for Defense DevelopmentDealroom has a profile for this one.

It supports on-premises setups for defense and financial customers that cannot send data to external clouds.
What's the money for? The funding will go toward upgrading the Akashic platform, developing a new product planned for the second half of 2026, expanding overseas, and hiring R&D staff. The plan is to convert pilots into full deployments and use domestic case studies as a base for foreign business.
Why it matters: "The success of enterprise AI depends less on the model than on how well it understands data and business context," said chief executive Kim Min-soo, framing the company's focus on hybrid RAG database engines.
The signal: At ₩17 billion, GraphAI's round sits above roughly 92% of all Series A deals recorded in South Korea, a sign of investor appetite for the data infrastructure layer beneath enterprise AI. Its next markers will be turning pilots into paying contracts and landing customers abroad.
