Sigma for modeling

Model every lever on live data

Change an input and the whole model recalculates on live warehouse data, so your team stops rebuilding it every week.

How it works

Build a model in 3 steps

  1. 1
    Set the assumptions

    Set rate bands and driver weights in an Input Table. Every value lands in the governed warehouse.

  2. 2
    Compare scenarios

    Duplicate the inputs, change 3 drivers, and see both versions on one chart in seconds.

  3. 3
    Lock and publish

    Approve the version, then share the model as an app. Audit history shows who changed which input.

Set the assumptions. Compare scenarios. Lock and publish

Version history

Every version keeps its own inputs

v11approved
The signed baseline
v12 draft2 of 3
3 inputs changed since v11
v12locked
Rate band, accelerator, payout cap

A reviewer can open any version and see which value went in, who changed it, and when it locked.

Built for real modeling depth

250+ functions in one workbook

Sigma keeps the formula freedom people expect from a spreadsheet, with 250+ functions and lookups on live tables. Custom SQL and Python run in the same workbook, so the logic stays together.

  • Write formulas, SQL, and Python against the same live tables
  • Query the warehouse live so no result rides on a stale extract
  • Prototype in a sheet, then ship the same logic as an app
02Act

Editable inputs with a full audit trail

The people who own the assumptions type them in, and writeback lands in the warehouse. Approvals lock a version, and the audit trail answers which value went in.

  • Type an override, lock the approved version, and trace every change
  • Keep production tables untouched with row-level inserts
  • Work from one governed metric definition across scenarios
03Govern

Governed AI in the loop

Sigma ships no model of its own. You point the workbook at your own LLM provider or a warehouse-native model, so every AI call runs inside the stack you already govern.

  • Route every AI call through the provider you already approved
  • Ask the Assistant which inputs drove a number
  • Review an agent's scenario, then accept or reject it

Always on the newest trusted data

Sigma queries your warehouse live, so a workbook reads what landed a moment ago.

Governance stays in the warehouse

Sigma queries live tables on Databricks and Snowflake, and others like BigQuery and Amazon Redshift, under your roles.

Live query, no extracts

Every calculation reads the warehouse at run time, so the model and the source never drift apart.

Row-level security inherited

Each contributor sees only the rows their warehouse role allows. One set of rules governs the model.

Audit history on inputs

Input Tables keep a full change history, so a reviewer can see which value went in and when.

Common modeling questions

Make modeling a standing capability
