Generate your enterprise knowledge graph and semantic model from source-system metadata
Flow.BI identifies which technical tables across different systems refer to the same real-world entity, and which foreign keys carry genuine business meaning rather than implementation plumbing.
Entities become nodes, relationships become edges, producing a machine-readable, queryable graph of how your business actually fits together — not an idealised glossary.
A semantic model maps your business vocabulary to physical structures, so a question phrased in business language resolves to the right tables and joins.
Every entity and relationship traces back to the source metadata that justified it, which separates a derived graph from a merely plausible-looking one.

An agentic analytics platform that turns questions into governed, trusted answers
Ask a question in plain language and get a reasoned answer with the SQL, charts and tables behind it, available in the Hex workspace, in Slack and from developer tools.
Write SQL, Python and R side by side in one project, then turn cells into interactive, parameterised data apps and dashboards without a separate BI authoring tool.
Centralise metrics, semantics and corporate definitions so answers stay consistent, and see exactly where the agent lacked grounding so you can fix it.
Run graded, rubric-based test suites against the agent to measure answer quality and catch regressions as your data and context evolve.
