Telmai
AI-driven data observability for open lakehouses with autonomous Data Reliability Agents
If you run a large lakehouse and need AI agents to handle data quality at scale, Telmai's Data Reliability Agents and natural-language interface deliver. But the lack of transparent pricing and no free tier turn smaller teams away. A demo is worth it for enterprises dealing with petabytes in Iceberg or Delta Lake.

Skip Telmai if you're a small team needing a free tier or low-cost entry, need on-premises deployment, or require sub-second real-time alerting—Telmai is a SaaS platform for enterprise-scale lakehouses.
Telmai doesn't publish pricing, so you'll need to contact sales for a quote—budget for a likely six-figure annual contract.
Telmai's contact-based pricing targets enterprise lakehouse teams, so it's not cost-effective for small teams—competitors like Great Expectations (open-source) or Soda Core offer free entry points. For enterprises with petabytes in Iceberg/Delta, Telmai's automation may justify the premium.
In short
Telmai — AI-driven data observability for open lakehouses with autonomous Data Reliability Agents. Best for Enterprise data engineering teams managing multi-cloud data lakes, AI/ML teams needing trustworthy data for model training and agentic workflows, Data governance and quality teams seeking automated validation and lineage.

About Telmai
Telmai is an AI-powered data observability platform built for open lakehouse architectures. It continuously validates structured, semi-structured, and unstructured data as it lands in cloud data lakes, generating context-rich quality metadata that both humans and AI agents can consume. Enterprise data teams use Telmai to automate pipeline validation, detect anomalies, and resolve incidents without manual effort. The platform features Data Reliability Agents including Orchestration, Validation, Incident Diagnosis, Lineage, Data Insight, Help, and Routing agents. It also offers a Data Health Dashboard, natural-language querying, and support for open table formats like Apache Iceberg, Delta Lake, and Parquet. Telmai integrates with 250+ tools and partners with Databricks, Google Cloud, and Microsoft OneLake. Recent developments include a partnership with iLink Digital and deeper integration with Google Cloud Lakehouse. Telmai is recognized as a G2 High Performer and trusted by companies like ZoomInfo, DataStax, PropertyGuru, and Clearbit.
Behind the Verdict
Telmai stands out in the data observability space by focusing on open lakehouse architectures, specifically supporting Apache Iceberg, Delta Lake, and Parquet. Its Data Reliability Agents—Orchestration, Validation, Incident Diagnosis, Lineage, Data Insight, Help, and Routing—automate many tasks that traditionally require manual effort. The platform's natural-language interface lets both technical and business users set up monitors and query data quality issues without deep SQL knowledge. Context-rich metadata generated by Telmai can be accessed by AI agents via MCP, which is forward-looking for teams building agentic workflows. However, Telmai is SaaS-only, meaning on-premises deployment isn't possible, and pricing is not public, requiring a sales conversation. For smaller teams or those needing a quick, low-cost solution, Telmai may be overkill. But for enterprises managing petabyte-scale data lakes with complex pipelines, Telmai's weighted validation, anomaly detection, and incident diagnosis can significantly reduce alert fatigue and improve data trust.

Real-world workflow fit
Concrete scenarios for the personas Telmai actually fits — and what changes day-one when you adopt it.
Set up monitoring for new streaming pipelines without writing custom scripts
Outcome: Use Validation Agent to auto-suggest rules, detect schema drifts, and get notified of anomalies in plain language—reducing setup time from days to hours.
Investigate a drop in sales metrics
Outcome: Use Incident Diagnosis Agent to identify root cause, see lineage graph, and generate a summary in plain English to share with stakeholders.
Give AI agents access to trusted data context
Outcome: Enable MCP server so agents can query Telmai's metadata and validated data to decide if data is fit-for-purpose—streamlining autonomous decision-making.
Use Cases
- Automate data quality validation across petabytes of Iceberg tables in a data lake.
- Detect schema drifts and anomalies in real-time streaming pipelines without custom scripts.
- Enable business users to ask natural-language questions about data health and get explanations.
- Reduce incident resolution time with AI-driven root cause analysis and lineage graphs.
- Ensure compliance and trust in data used for AI agent workflows with context-rich quality metadata.
- Monitor business metrics (e.g., total sales, average transaction) for drift across millions of dimensions.
- Use Data Reliability Agents to automate onboarding, rule suggestion, and incident routing.
- Integrate with Microsoft OneLake to continuously validate data for AI and analytics.

Where the pricing makes sense
The company stage and team size where Telmai's pricing actually pencils out — and where peers do it cheaper.
Telmai's contact-based pricing targets enterprise lakehouse teams, so it's not cost-effective for small teams—competitors like Great Expectations (open-source) or Soda Core offer free entry points. For enterprises with petabytes in Iceberg/Delta, Telmai's automation may justify the premium.
Setup time & first value
How long it actually takes to get something useful out of Telmai — broken out by persona, not the marketing-page minute.
For existing lakehouse teams, basic monitoring can be set up in a day using native Iceberg/Delta integrations; full configuration with Data Reliability Agents may take 1-2 weeks for complex pipelines. Business users can start querying in plain English immediately after onboarding.
Switching to or from Telmai
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Great Expectations: Recreate your validation rules in Telmai's SQL or no-code interface, then let the Validation Agent auto-suggest rules based on trends.
- →From Soda: Use Telmai's connectors to connect to the same data sources and import existing monitors via API or manual setup.
- ↗To Great Expectations: Export your validation rules and adapt them to GX's Python API—Telmai's metadata can inform your expectations.
- ↗To Monte Carlo: Recreate monitors and alerts in Monte Carlo's UI; lineage data can be exported for reference.

Featured Head-to-Head Comparisons
Telmai vs Presto Voice
Presto Voice and Telmai serve entirely different domains: drive-thru AI automation vs. data observability. Choose Presto Voice if you run a QSR chain seeking voice AI to boost revenue and efficiency via upselling. Choose Telmai if you manage enterprise data lakes/lakehouses and need AI-powered data quality, anomaly detection, and lineage. There is no overlap; the decision hinges on your industry: restaurant operations vs. data engineering.
Telmai vs Truleo
Choose Truleo if you're in law enforcement needing to connect siloed data (RMS, CAD, jail calls) and automate lead generation. Choose Telmai if you're an enterprise data team managing multi-cloud data lakes and need AI-driven observability. No overlap in use cases, so pick based on your domain.
Telmai vs Screenplayiq
If you need to predict box office returns from a script or get structural feedback, ScreenplayIQ is your only choice—its free tier and affordable Pro plan make it accessible for indie screenwriters. For enterprise data teams ensuring quality across lakes and lakehouses, Telmai offers deep observability with AI-driven agents, but it lacks a free tier and is SaaS-only. Choose based on whether your problem is creative storytelling or technical data reliability.
