EU-Startups has learned that Spain and U.S.-based Modern Relay, a shared foundation for enterprise AI, has raised a €2.5 million ($3 million) funding round along with releasing its first open-source product, Omnigraph – a Git-style graph database built for a world where agents are first-class operators.
The round was raised with participation from Point Nine, Emerge, Amino Collective, Common Magic, and angels including Charlie Songhurst (board member at Meta), Michael Boehler (former BioNTech executive), and Thomas Clozel (co-founder of OWKIN).
“Every company will soon rely on a growing number of agents across all departments,” says Ragnor Comerford, co-founder of Modern Relay. “Without a shared foundation connecting them, those systems create more fragmentation than leverage. We’re building the layer that lets organisations preserve context, coordinate work, and stay in control.”
Related funding activity in AI infrastructure and adjacent tools from 2025–2026 includes:
- Germany: Cognee in Berlin raised €7.5 million to scale enterprise-grade memory technology; Interloom in Munich secured €14.2 million to build AI agent knowledge infrastructure; and Blockbrain in Stuttgart raised €17.5 million to strengthen security and governance and expand its enterprise AI agents platform.
- Spain: Galtea in Barcelona raised €2.7 million for its AI evaluation platform; and SLNG.ai in Barcelona secured €3.3 million for speech AI infrastructure.
- Other: Kestra in Paris landed €21 million to expand its orchestration platform; and Rerun in Stockholm raised €15.6 million to build multimodal data infrastructure for Physical AI.
Together, these rounds amount to over €81 million, giving a sense of the capital flowing into the sector and giving context to today’s announcement.
Set against that backdrop, Modern Relay’s €2.5 million round fits a clear pattern of investor interest in the foundational software needed to make enterprise AI systems operational, governable, and interoperable across organisations.
The strongest overlaps are with companies building memory, orchestration, evaluation, and knowledge layers for AI systems rather than end-user applications alone. There is also a relevant geographic angle: Galtea and SLNG.ai show comparable AI infrastructure activity from Spain, and specifically Barcelona, which is worth calling out given Modern Relay’s base there.
“We backed Modern Relay because Ragnor and Aaron understood the fundamentals of this new reality early,” says Ricardo Sequerra, Partner at Point Nine. “The bottleneck has moved from model capability to organizational infrastructure. They’re building the operational backbone for how AI actually works inside a company.”
Founded in 2025 by Ragnor Comerford and Aaron Go, Modern Relay builds the shared foundation for enterprise AI. Its context graph helps organisations coordinate work across people, software, and agents while governing how knowledge and operations evolve over time.
The company says that organisations are already running multiple agents to draft research, ship code, and handle day-to-day operations. The moment those agents touch anything cross-functional, they hit the same wall: organisational context is scattered across documents, chats, legacy databases, and knowledge that was never written down.
Without a shared layer where people and agents can work from the same facts and rules, every department automates in isolation.
Modern Relay is building the infrastructure to address this. Its system gives organisations a shared foundation for how the company actually works (its people, policies, data, and decisions) so that software and teams coordinate from the same reality.
That makes it possible to route the right information to the right actor at the right time, while governing what changes, who approves it, and how work evolves over time.
Modern Relay believes that as AI embeds deeper into enterprise operations, that foundation becomes the most valuable asset a company has.
“Nothing this central to how a company operates should live inside someone else’s platform, which is why Modern Relay runs entirely on infrastructure the customer owns,” said the company.
