deepset, the company behind the Haystack open-source AI agent framework, announced on June 18 that it has joined HPE’s Unleash AI partner program. The partnership combines deepset’s Haystack Enterprise Platform with HPE’s infrastructure portfolio to let government, defense, and regulated enterprises deploy multi-agent systems in sovereign, self-hosted, and air-gapped environments.

What the Partnership Delivers

The joint architecture targets organizations that cannot send data to third-party cloud providers. Customers get access to HPE Private Cloud AI and HPE AI Factory (built on NVIDIA hardware) running deepset’s Haystack Enterprise Platform for building, orchestrating, and governing AI agents and RAG applications.

Supported use cases, according to the announcement, include sovereign AI platforms for public sector institutions, intelligence and decision-support systems for classified operations, cybersecurity threat analysis, and AI agents for manufacturing, research, legal, and financial workflows.

“With agentic AI moving into operational deployment, organizations need infrastructure and AI platforms they can control and trust,” deepset CEO Milos Rusic said in the announcement. “The challenge is getting agentic systems into production while maintaining control over infrastructure, governance, and sensitive data.”

Robin Braun, HPE’s VP of AI Business Development, Hybrid Cloud, described the program as helping “organizations deploy AI solutions faster and with greater operational confidence” across “hybrid, sovereign, and classified environments.”

Why deepset, Why Now

deepset was founded in Berlin in 2018 and developed Haystack, its open-source Python framework for AI agents and applications, starting in 2020. The framework provides modular pipelines with explicit control over retrieval, routing, memory, and generation. Gartner named deepset a Cool Vendor in AI Engineering in November 2024.

The company’s existing customer base already skews heavily toward European institutions. According to deepset’s partner page, organizations including the European Commission, Airbus, the German Armed Forces, and The Economist use Haystack in production. The PR Newswire announcement adds the German Ministry of Research, Technology and Space (BMFTR) to that list.

HPE’s Unleash AI program is a curated ISV ecosystem where partner solutions go through validation testing against HPE’s engineered AI systems. deepset joins alongside other validated partners building on HPE Private Cloud AI infrastructure.

The Sovereign AI Demand Signal

The announcement lands in a week dominated by sovereign AI themes. Anthropic’s ongoing export control dispute with the Trump administration has forced organizations relying on US-built frontier models to reconsider their infrastructure dependencies. India’s sovereign AI gap, exposed by the Fable 5/Mythos 5 restrictions, highlighted the risk of building agent applications on top of foreign foundational models without fallback options.

deepset’s positioning is distinct from both the consumer-facing open-source tools (like OpenClaw) and the US hyperscaler agent platforms. Haystack’s value proposition is governance-first: organizations retain full ownership over data, models, and AI operations while deploying agents that run entirely on infrastructure they control. For a European Commission or German defense agency evaluating agent deployment options in mid-2026, the pitch is straightforward: agent capability without sovereignty tradeoffs.

The partnership also reflects HPE’s bet that enterprise AI infrastructure sales will increasingly be driven by agent workloads rather than pure training or inference. By validating deepset’s Haystack against its Private Cloud AI stack, HPE is positioning sovereign agent deployment as a first-class infrastructure category alongside traditional HPC and cloud computing.
