Raised €7.5M seed (Feb 2026) led by Pebblebed with OpenAI and FAIR founders as backers. Open-source knowledge graph + vector memory for AI agents. Claude SDK integration. Prevents hallucinations via persistent structured memory.
Cognee is an open-source knowledge graph and vector memory engine designed specifically for AI agents — providing persistent, structured memory that prevents hallucinations by grounding agent responses in verified organizational knowledge rather than parametric model weights. The company raised €7.5 million ($8.2 million) in seed financing in February 2026, led by Pebblebed and backed by founders from OpenAI and Facebook AI Research (FAIR). Cognee has integrated with the Claude SDK, making it directly accessible to teams building on Anthropic's models.
a2z Radiology AI raised $20M in 2025 for its whole-body AI that simultaneously screens for 24+ conditions across CT scans — from incidental cancers to cardiovascular risk — in a single automated read.
a2z Radiology AI has developed a whole-body CT analysis platform that simultaneously screens for over 24 medical conditions across a single CT scan, including incidental cancers, coronary artery disease, aortic aneurysm, bone density loss, and organ abnormalities. The AI acts as a second reader that radiologists can use to catch incidental findings that fall outside the primary reason for a scan — a major source of missed diagnoses.
