deepset

deepset is an AI infrastructure company that provides a sovereign AI platform for building, running, and governing custom AI agents and applications with full ownership and control over infrastructure, models, and data boundaries. The company's flagship product, Haystack, is an open-source platform that enables organizations to build context-engineered agents and RAG systems where every step is explicit, inspectable, and modifiable, with no black-box agent loops. Haystack supports visual pipeline design and full-code development in one place, with agent primitives including tools, memory, retrievers, and pipeline components that users can own, swap, and extend without proprietary lock-in. The platform enables deployment anywhere, cloud or self-hosted, with audit logs, role-based access control, and data lineage built in for compliance. Haystack's capabilities span retrieval augmented generation, intelligent document processing, enterprise search, text-to-SQL, data indexing, visual pipeline building, stakeholder testing, governance, and deployment. deepset serves enterprises and government organizations in regulated, high-impact environments, with production deployments including building Europe's sovereign AI platform for the European Commission, context engineering at Bosch scale, and secure AI delivery for the German Federal Ministry. The company recently launched Haystack 3.0 and partnered with Mozilla on a unified sovereign AI stack connecting Thunderbolt AI client with Haystack infrastructure orchestration. Founded in 2018 and headquartered in Berlin, Germany, deepset has raised $45.6M in Series B funding from investors including Google Ventures, System.One, Harpoon, Acequia Capital, Lunar Ventures, Balderton Capital, Tiny, and MK Venture Capital.
