Cognee vs Skild AI
Side-by-side comparison of AI visibility scores, market position, and capabilities
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.
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.
Universal robot brain startup raised $1.4B Series C at $14B valuation in Jan 2026 led by SoftBank with Nvidia and Bezos; $30M 2025 revenue; deployed at Foxconn
About
Skild AI is building a universal robot brain — a foundation model for physical intelligence that can power a broad range of robot types without requiring task-specific training for each deployment. Founded to solve the fragmentation problem in robotics AI, where every robot type and task requires separate model development, Skild's approach trains a single generalist model on diverse robotic data and fine-tunes it rapidly for specific deployments. The company was founded by robotics AI researchers who identified the model reuse gap as the primary barrier to scalable robot deployment.\n\nSkild's generalist robot model has been deployed across more than 30 distinct robot types — spanning manipulation arms, mobile platforms, and humanoid form factors — demonstrating the cross-hardware generalization that most robot AI systems lack. The platform targets robotics manufacturers, logistics operators, and industrial automation companies that need AI-capable robots but lack the internal ML infrastructure to develop foundation models themselves. By offering a model-as-a-service layer, Skild enables robot OEMs and systems integrators to add AI capabilities without building the underlying research infrastructure.\n\nSkild AI raised a $1.4 billion Series C in January 2026 at a $14 billion valuation, led by SoftBank with co-investment from NVIDIA and Jeff Bezos. The round was one of the largest in robotics AI history and reflects institutional conviction in the physical AI market's scale. With $30 million in 2025 revenue and accelerating enterprise deployments, Skild is building the financial foundation to match its valuation. The SoftBank-NVIDIA investor combination positions Skild at the center of the global robotics deployment wave.
