- Strong data-privacy stance
- Connects to many DBs and warehouses
- YC-backed (W23)
- Pricing not publicly listed
- Small team and product
- Scope focused on SQL analytics
Tellius
Beyond NL-to-SQL — it autonomously investigates why a metric moved, ranking drivers across hypotheses, and returns board-ready memos rather than dashboards.
- Automated root-cause and driver analysis
- Conversational NL analytics (Kaiya)
- Proactive 'missions' monitor KPIs
- Outputs presentation-ready insights
- Enterprise sales motion; no public pricing
- Overkill for simple dashboards
- Smaller ecosystem than BI incumbents
