Self-service that stays inside your warehouse
Your teams already get answers from exports, spreadsheets, and AI chat. Sigma gives them that speed on live, governed warehouse data.
Ask in plain language
Sigma Assistant answers from live warehouse data and shows which data it used.
Explore past the dashboard
Filter, pivot, and drill to the row in a spreadsheet people already know.
IT sets the rules once
Permissions, badges, and audit logs come from IT, so self-service stays governed.
Trusted by 2,000+ leading enterprises around the world
Self-service people use daily
Teams at Duolingo and Vanta answer their own questions on governed data.
“Using Sigma, I was able to make a dashboard in under two hours that got the answers. The AI features let our team move faster than ever before.”How Duolingo Democratized Data Access While Protecting Sensitive Information
“We can do it all ourselves in seconds. It's saved us hours of manual work per campaign.”How Vanta Tripled Campaign Performance with SigmaYour teams already self-serve where IT can’t see it
Spreadsheet copies and AI-built dashboards, apps, and agents spread faster than anyone can track.
Today
With Sigma
Sigma gives every workaround a governed home
IT sets the controls once, in the warehouse. People ask, explore, and build on live data with their own permissions, and IT sees all of it.
Trusted numbers
Everyone gets the same current number
Sigma queries your warehouse directly, and data models hold your shared metric definitions. Dashboards, Sigma Assistant, and agents answer from today’s data with the same logic.
- Live queries, no extracts
- dbt metrics and warehouse semantics
- Open Semantic Interchange launch partner
Same permissions
Permissions you set once apply everywhere
Queries run in your warehouse, and with OAuth, as each person’s own warehouse role. There are no extracts to copy out and re-secure by hand.
- Row-level and column-level security from user attributes
- SSO and SCIM keep users and teams in step
- No extracts to secure
Your way
Work the way you already work
Prompt Sigma Assistant, build in a spreadsheet, or write Python and SQL in the same workbook on live data. A quick question can grow into an analysis the team reuses.
- Prompts, spreadsheet formulas, Python, and SQL side by side
- Each path runs with the person’s own permissions
- Explains any chart in plain language
Full detail
Go from the total to the transaction
Filter, pivot, and drill on billions of rows in the spreadsheet interface people already know. Save the view for next time.
- Spreadsheet functions and pivots on live data
- Drill into any published chart
- Saved views that leave the original untouched
Add context
Add what only your team knows
Type forecasts, comments, corrections, and plans into a table beside the live data. Entries save to your warehouse with a change history, so the next report already includes them.
- Stored in Snowflake, Databricks, BigQuery, or Redshift
- Who changed what, and when
- What-if scenarios you can rerun
Work anywhere
Build on trusted data from anywhere
Connect Claude, ChatGPT, Cursor, or your own agents with the Sigma MCP server and CLI. Query your governed data models, or build Sigma apps on them, with each person’s permissions.
- Works with any MCP client
- Build apps from a coding agent
- Same permissions, same audit logs
Governed AI
Choose the model and see each agent
Admins pick the AI provider, including models hosted in your warehouse. Sigma Assistant and agents answer only from data each person can already see.
- Warehouse-hosted models supported
- Answers within each person’s permissions
- Each agent, its owner, and its token use

What changes when people answer their own questions
Analysts, product managers, and finance leaders, in five-star reviews on G2 and Gartner Peer Insights.
“The best aspect of Sigma for me is the ease of use for non-technical users. I had someone who had never been able to self-serve data prior to Sigma sending me workbooks within a week of going live.”
VP, Data EngineeringBanking · Gartner Peer Insights (opens in a new tab)“The application provides a GUI frontend that leverages users' existing Excel skillsets to generate SQL code on the back end, building queries and datasets without requiring technical or coding skills.”
EngineerTelecommunication · Gartner Peer Insights (opens in a new tab)“This product has allowed us to put effective self-service data back into our business users' hands and alleviated most of the ad hoc requests for data that we receive daily.”

Questions IT asks before rollout
Does Sigma copy our data?
No. Sigma queries your warehouse directly.
How do permissions work?
Sigma connects to your warehouse and can run each query with the viewer’s own warehouse role. Row-level and column-level security apply to dashboards, Sigma Assistant answers, and agents alike, so nobody sees more in Sigma than they could in the warehouse.
How do we keep people on trusted data?
Badge the data models and workbooks people should build on, flag the ones they shouldn’t, and promote changes from dev to prod with version tags.
What license do people who only read dashboards need?
A View license, which is built for report consumers. Your account team can walk through pricing.
Which AI models does Sigma use, and what can they see?
Admins choose the model provider, including models hosted in your warehouse. Sigma Assistant only answers from data the person can already access, and conversations are logged.
How is this different from pasting data into an AI chat?
Data pasted into a chat leaves your warehouse and its controls. Sigma Assistant answers on live data under each person’s permissions, and the Sigma MCP server gives Claude and ChatGPT that same governed access.
Can business users change data?
Only in the Input Tables you allow. Entries are stored in your warehouse with a change history, under the same permissions as everything else.
What can admins see?
Audit logs record who built, viewed, and changed what, along with AI conversations and API calls. Usage dashboards show adoption, exports, and query runtime.
