The record

Product: HASH describes itself as an open-source platform that turns organizational information into an continuously updated world model combining a knowledge graph with a process graph.
Purpose: The platform supports analytics, workflow automation, what-if simulations, AI agents, and fine-grained access governance using its organizational model.
Data capture: HASH can ingest connected apps and structured data, infer entities from unstructured sources, and passively capture information from the web.
Graph history: Its bitemporal graph stores transaction and decision time so users can inspect historical states and provenance without destructive overwrites.
Automation: Flows combine triggers, actions, filters, and waits and can run manually, automatically, or programmatically; agents can also take actions and answer questions.
Integrations: The published integration directory includes services such as Slack, Google Drive, Gmail, Notion, GitHub, SAP S/4HANA, Snowflake, and Postgres.
Sync limits: HASH says integrations support two-way synchronization where possible, while some services may only permit read-only sync or one-time imports because of API limitations.
Extension: The browser extension lets agents access websites on a user's behalf, passively collect selected information while browsing, and launch flows from a page.
Self-hosting: HASH can be self-hosted, but its guide says this requires technical knowledge and recommends it for advanced users.
Security: HASH says its information security program follows the SOC 2 framework and that independent third-party assessments, including penetration testing, occur at least annually.
Privacy controls: The security page states that HASH is GDPR compliant, offers EU-only hosting, and is recognized under the EU-US, UK extension, and Swiss-US Data Privacy Frameworks.
Support: The download page directs users to contact support or consult the user guide for help.
Limits: Pricing lists Free manual scraping at 50 entities per job and Plus at 1,000; Team includes one concurrent active scraping job, while Ultra lists unlimited concurrent jobs.
Company: HASH says it is based in London, Berlin, and New York.
Price from: $1.67/mo
