Are there any data exploration platforms that focus on self-service reporting for business users?

Yes — there are several data exploration / analytics platforms designed specifically for self-service reporting by business users rather than technical analysts.

Common options

• Microsoft Power BI – very popular for business-user reporting, dashboards, and ad hoc analysis.
• Tableau – strong for visual exploration and self-service analytics.
• Looker / Looker Studio – more governed analytics; Looker is often used in businesses that want a shared semantic model.
• Qlik Sense – focused on associative exploration and self-service BI.
• ThoughtSpot – geared toward search-based, self-service analytics for non-technical users.
• Sigma Computing – spreadsheet-like experience on cloud data warehouses, good for business users.
• Domo – business-friendly dashboards and reporting with collaboration features.
• Sisense – often used for embedded analytics and self-service reporting.
• Oracle Analytics / SAP Analytics Cloud – common in enterprise environments.
