Cognee is a Berlin-based AI infrastructure startup founded in 2024 that converts unstructured data into a persistent, graph-based memory layer for AI models and agents. Its technology enables systems to retain context over time, reason across connected information, and lower hallucination rates, addressing a core limitation of stateless retrieval and short context windows. Originally launched as an open-source project, Cognee has been adopted by thousands of developers, with more than 70 companies already running it in production, especially in knowledge-intensive and regulated sectors. The company is enhancing its core memory and graph engine while adding enterprise-grade reliability and scalability features. Cognee’s team operates across Europe and the United States and is positioning its platform as foundational infrastructure for global AI deployments. The recent €7.5 million raise provides capital to accelerate product development and support rising commercial demand.
