Tellius is an agentic analytics platform that connects to 12+ enterprise data sources, including Snowflake, BigQuery, and Databricks, letting business teams ask natural-language questions and get automated root-cause analysis instead of building manual dashboards. It targets data-intensive pharma, financial services, CPG, and retail organizations that need governed, self-service BI without writing SQL.
About Tellius
Tellius is an AI-powered decision intelligence platform founded in 2015 and backed by $36.1M in Series B funding, with SOC 2 Type II certification for enterprise security. It replaces static dashboards with a natural-language interface and agentic AI workflows that investigate performance changes, uncover root causes, and execute multi-step analyses without manual intervention. The platform runs on a dual AI engine built on Apache Spark, combining deterministic analytics with LLM reasoning to analyze billions of data points and connect business questions directly to explainable, auditable actions. Pharma, financial services, CPG, and retail teams use it to move revenue, finance, and supply-chain reporting from reactive dashboards into proactive, autonomous decision-making.
Pricing
Two tiers with custom pricing: Pro (governed conversational analytics + automated root cause investigation, streamlined deployment) and Enterprise (adds proactive workflows, orchestration, SSO/RLS, dedicated support). No per-user fees—pricing based on deployment scope and data volume. No free tier or self-serve trial.
Key Features
- AI Agents & Agentic Flows: Autonomous AI agents that plan, reason, and execute multi-step analytical workflows without human intervention, transforming questions into actions in minutes
- Natural Language Interface: ChatGPT-like conversational interface enabling anyone to ask questions of enterprise data in plain language, with automatic SQL and Python code generation
- Automated Root Cause Analysis: Machine learning-powered investigation that automatically uncovers hidden drivers, anomalies, and key performance correlations across billions of data points
- Semantic Layer & Data Governance: No-code semantic modeling that unifies data sources, enforces consistent KPI definitions, and ensures governed, auditable decision-making at scale
- Predictive & AutoML Modeling: Point-and-click or code-based machine learning for forecasting, anomaly detection, segmentation, and custom model development without data science expertise
- Generative Insights & Narratives: AI-driven narrative generation that auto-writes executive summaries, variance analysis, and board-ready reports with full traceability to source data
Pros
- Autonomous agents run root-cause investigations end to end, so analysts spend less time digging through data and more time acting on it
- No-code semantic layer keeps KPI definitions consistent across departments, so finance and RevOps work from the same numbers
- SOC 2 Type II certification plus row-level security make the platform usable for regulated industries like pharma and financial services
- Explainable output traces every insight back to source data, which builds trust compared to black-box scoring
Cons
- Custom pricing with no self-serve tier, requires a consultative sales process and demo
- Steep initial configuration overhead due to semantic layer setup and data onboarding
- Limited native CRM and workflow automation, pair with separate engagement tools for RevOps use cases
- Relatively young in the agentic analytics category compared to established BI vendors
Frequently Asked Questions
How much does Tellius cost in 2026?
Tellius sells two custom-priced tiers: Pro (governed conversational analytics and automated root-cause investigation) and Enterprise (adds proactive workflows, orchestration, SSO, and row-level security). There are no per-user fees; pricing instead scales with deployment scope and data volume, and every purchase goes through a sales conversation rather than a self-serve checkout.
Is Tellius free to use?
No. Tellius has no free tier and no self-serve trial: both the Pro and Enterprise tiers require a demo and a consultative sales process before you get access. Budget time for implementation too, since the semantic layer has to be configured against your own data before the AI agents can run.
What are the best alternatives to Tellius?
ThoughtSpot is the closest match for agentic, self-service BI and includes a free tier that Tellius doesn't offer. Qlik suits teams that want a broad data integration and analytics platform with a 40,000+ organization install base rather than an agent-first workflow. Pick Tellius instead when the priority is autonomous root-cause investigation with a governed semantic layer.
How does Tellius compare to ThoughtSpot in 2026?
Both build agentic, self-service analytics around natural language, but ThoughtSpot offers a free tier and self-serve pricing starting at $25/month, while Tellius is enterprise-only with custom pricing and no free plan. Tellius leans harder into autonomous multi-step investigation and a governed semantic layer for regulated industries; ThoughtSpot is the easier entry point for smaller teams.
How do you get started with Tellius?
Since there is no self-serve signup, request a demo through tellius.com and come prepared with your data volume and target use case. Sales scopes you into the Pro or Enterprise tier, and onboarding centers on configuring the semantic layer so KPI definitions stay consistent before the agents start running analyses.
Top Alternatives
- ThoughtSpot: Pick ThoughtSpot if you want a free tier and self-serve pricing; pick Tellius if you need a governed semantic layer for regulated, multi-department reporting.
- Qlik: Pick Qlik if you want a widely deployed data integration platform with an established BI community; pick Tellius if you want agent-led root-cause investigation, not just dashboards.
