HASH
Open-source workspace for structured knowledge, workflows, simulation, and governed AI agents.
HASH is the current canonical product name.
About HASH
HASH is an open-source workspace for turning operational information into a structured, continuously updated world model. It combines typed entities and relationships with process graphs, so teams can integrate data, automate workflows, run simulations, and give AI agents governed business context from one system. Bitemporal storage and provenance retain how facts and decisions changed, while granular permissions support multi-tenant use. HASH can serve as a source of truth or sit alongside an existing warehouse or lake. The managed service has a permanent Free plan, paid individual and team tiers, and a sales-led Ultra tier. This scope suits organizations that want a shared semantic and operational layer, but adoption requires modeling types and processes. Several collaboration or automation capabilities also sit behind paid tiers or waitlists.
