Insights for teams building Secure Knowledge Infrastructure on foundation4.
We made a decision early on to leverage PostgreSQL and pgvector for our data store instead of a dedicated vector database. Our single-stack architecture allows us to deliver capabilities that split-system architectures struggle to match.
We believe your data is yours and we deliver the secure knowledge infrastructure to keep it that way --- embedding, storage, retrieval, and generation in a single self-managed platform --- engineered so that no proprietary data ever crosses your network boundary.
