Y Combinator-backed startup Hyper is launching an AI-powered company brain that uses knowledge graphs and large language models to structure enterprise domain knowledge for agentic workflows. The platform stores facts as interconnected subject-predicate-object records in a Postgres database, enabling AI agents to perform dynamic graph traversals to maintain deep business context. Addressing community questions during the launch, founders clarified their strict no-training data privacy policy and explained how the system uses supplementary tool calls to mitigate potential context loss.
