Telmai is a data quality and observability platform for teams monitoring data in lakes, lakehouses and connected pipelines. It tracks health measures including freshness, completeness, correctness and uniqueness, and can alert when data is stale or delayed. The product is positioned for mid-market and enterprise teams, with cloud and self-hosted deployment options. Its focus is a fit for organizations that need more than a single freshness check, particularly when data health monitoring needs to connect to investigation and remediation work.

Monitoring covers schema changes such as added or removed columns, as well as drift and anomalies measured against learned baselines. Teams can use built-in monitors, define their own, apply record-validation monitors, and create custom metrics with expressions or SQL. Telmai also maps lineage across sources and targets and supports comparisons between source and target tables. Listed integrations span services and formats including Amazon Redshift, Amazon S3, Databricks, Delta Lake, Apache Iceberg, Azure SQL and CSV; the product details describe 250 integrations. This breadth suits varied data environments, while buyers should confirm that their specific systems and workflows are supported.

Telmai offers alerting, ticketing, investigation and remediation workflows, making it relevant where monitoring needs to feed follow-up actions rather than stop at detection. It is available as public SaaS or for deployment in a customer’s VPC, and its compliance listing includes SOC 2. Pricing uses a contact-sales model, so teams should expect to discuss plans with the vendor rather than select from published tiers. Documentation is the listed support channel. Telmai is worth considering for mid-market and enterprise teams that need flexible checks across data systems; teams seeking transparent self-serve pricing or support beyond documentation may prefer to evaluate alternatives.
