As organizations across Europe accelerate AI adoption, many are re-evaluating the infrastructure behind retrieval, analytics and real-time insights. Concerns about vendor lock-in, rising costs and data sovereignty are driving demand for open, community-governed platforms. Recent research on sovereign AI shows that 83% of European leaders view it as a strategic priority, reinforcing the importance of community-driven innovation and technologies.

“Global leaders are taking a more deliberate approach to AI infrastructure,” said Bianca Lewis, executive director of the OpenSearch Software Foundation. “Organizations are looking for platforms that support innovation without sacrificing control, cost transparency or long-term flexibility. As AI agents become more embedded in business workflows, modern search must provide the real-time context, multi-model retrieval and governance those systems depend on. OpenSearchCon Europe gathers the builders and decision makers that are shaping how open-source search, observability and vector technologies will power the next generation of AI applications.”

Keynotes and sessions will explore the future of search and AI with analyst expertise from S&P Global, OpenSearch’s feature advancements and roadmap, real-world OpenSearch migration stories from organizations like the Norwegian Labor and Welfare Administration, and best practices for observability and analytics.
