Sigma Computing

Founded in 2016, Sigma lets analysts and non-technical users write SQL queries that run directly against Snowflake, BigQuery, or Redshift without leaving a spreadsheet-like interface. You get live data access and real-time SQL translation, so the query logic stays intact while the UX feels familiar to anyone who's used Excel. The platform handles both ad-hoc exploration and shared, production dashboards in one tool.

Sigma fits data teams who want live data access without extracting and loading into separate BI tools. It's stronger than traditional BI for exploratory analysis since you can drill into data at the table level, but weaker than specialized visualization platforms if you need highly polished dashboards for stakeholders.
