POSCO DX COMPANY LTD. advances Agentic AI with ontology technology

[Financial News] POSCO DX COMPANY LTD. is moving to enhance Agentic AI using ontology technology. The plan is to use ontologies to structure employees’ accumulated work know-how and tacit knowledge as knowledge assets, thereby boosting the capabilities of AI agents.
POSCO DX COMPANY LTD. said on the 11th that it had invested 2 billion won in Inhaenseu, a startup that developed AgentOS, an ontology-based enterprise AI operating system, through the “POSCO DX Corporate Venture Capital (CVC) New Technology Investment Partnership,” which it co-funded with POSCO Technology Investment. It also said it had signed a business agreement to build AI agents specialized in executing work.
Ontology is a technology that structures scattered data around its business meaning and relationships, helping AI understand work as a whole. Its strength lies in its ability to convert even tacit knowledge—such as experienced workers’ know-how, handling of exceptional situations and decision-making criteria, which are difficult to clearly capture in systems or documents—into data assets and incorporate it into AI agents.
Inhaenseu is an enterprise Agentic AI company that connects corporate data and work contexts through ontologies and enables AI agents to perform actual tasks. Before this collaboration, POSCO Group applied Inhaenseu’s “AgentOS” to office work within the group and is verifying its effectiveness. Based on this, it is developing AI agents for tasks such as financial profitability analysis and reviewing their potential for practical use.
The two companies plan to expand the ontology-based Agentic AI technology validated in office work across industrial sites, including production, facilities and logistics. POSCO DX COMPANY LTD. plans to combine its business experience and know-how in each domain with Inhaenseu’s AgentOS and gradually complete industry-specific AI solutions for sectors such as steel and logistics.
This initiative by POSCO DX COMPANY LTD. also coincides with the growth of the Agentic AI market. Global market research firm MarketsandMarkets forecasts that the enterprise Agentic AI market will grow at an average annual rate of at least 47% to reach about $46 billion by 2030. It also expects AI to rapidly move beyond simply generating answers and into the Agentic AI stage, in which it performs actual business tasks.
Meanwhile, POSCO Group is expanding and operating CVC funds for venture investment in ways tailored to its business companies, seeking to identify innovative technologies and promising businesses of the future. Through this, POSCO DX COMPANY LTD. plans to make strategic investments this year in companies developing industrial humanoid robots and domestic AI semiconductor startups, among others, and to respond proactively to the spread of AX across POSCO Group and the transformation of industrial paradigms.
