Sema

Product: Sema is a semantic layer for enterprise AI that connects databases, infers data meaning, and answers business questions in plain English with governance.
Querying: Sema asks clarifying questions, shows the SQL it ran and graph nodes traversed, and automatically selects a chart for the answer.
Semantic graph: Tables, joins, metrics, and business terms are represented in a typed graph, and verified inferred joins can be reused by future answers.
Reports and alerts: Users can save and schedule reports for email delivery, and create scheduled threshold or deviation alerts on metrics.
Security: Sema says it uses TLS in transit and encryption at rest, role-based access, restricted-column masking, workspace isolation, and an append-only log of queries, plans, and configuration changes.
Compliance: Sema’s trust page says SOC 2 Type II is in progress, GDPR-ready data processing terms are available, and HIPAA support with a BAA is available for eligible plans on request.
Deployment: Sema says it can run in the customer’s VPC or its own environment; its self-hosted Kubernetes deployment uses a Helm chart and customer-provided Postgres and object storage.
Integrations: Sema describes its capabilities as MCP tools for use with Claude, Cursor, or an in-house agent, and supports OAuth2/OIDC identity providers including Okta, Entra, Auth0, and Google Workspace.
Limits: The free Sandbox includes one connector, one user, 100 chat queries per month, five saved reports, and no scheduled delivery, alerts, or signals.
Support: The Pro plan includes email support, Business includes priority support, and Enterprise includes a named customer success manager.
Audience: Sema describes itself as built for enterprise and regulated teams, and its About page says it is designed for warehouses with thousands of tables.
Company: Sema says it was founded in 2025 and is remote-first.
Founded: 2025
Price from: $49/mo
