About
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.
Decentralized Web3 infrastructure with RPC node access across 30+ blockchains; globally distributed nodes reduce latency; premium dedicated nodes for apps needing guaranteed throughput.
About
Ankr is a Web3 infrastructure platform offering remote procedure call node access to more than 30 blockchain networks through a globally distributed network of nodes run by independent operators. Unlike centralized providers that operate their own data centers exclusively, Ankr's decentralized architecture routes requests across geographically distributed nodes, improving latency for users in regions underserved by US- or EU-centric infrastructure. Its public free-tier RPC endpoints — available for Ethereum, BNB Chain, Polygon, Avalanche, Fantom, and dozens of others — have made Ankr one of the most widely used infrastructure providers in the multi-chain developer ecosystem.
