German AI infrastructure startup Cognee lands €7.5 million to scale enterprise-grade memory technology

Berlin-based AI infrastructure startup Cognee has secured €7.5 million in a funding round led by Pebblebed, with participation from 42CAP and angel investors. This capital injection is designated to accelerate the development of Cognee's structured memory layer for AI systems and agents, a critical component for enabling AI to understand context beyond simple text retrieval. The company's focus on foundational AI infrastructure underscores a broader trend in European investment, prioritizing the building blocks for advanced AI deployments. Cognee's technology addresses the fundamental limitation of current AI systems lacking robust, long-term memory. By transforming unstructured data into a persistent, structured memory layer utilizing knowledge graphs and semantic representations, Cognee's solution allows AI to retain context, reason across connected information, and reduce hallucinations. This approach is particularly vital for complex, long-running, and business-critical AI applications. This funding round places Cognee within a growing ecosystem of European startups bolstering the continent's AI capabilities. The investment follows a series of significant funding rounds across Europe, totaling approximately €86.4 million, dedicated to AI databases, agent security, workflow orchestration, vertical AI agents, and cloud infrastructure. Cognee's contribution to this landscape aims to provide a core building block for the global AI stack, emphasizing infrastructure over end-user applications and contributing to Europe's digital sovereignty.
