Telmai is a software development company based in San Mateo, California, focused on AI-powered data quality and observability with an open-architecture design. Its platform aims to provide end-to-end data visibility by evaluating datasets for column-level quality issues and automatically excluding problematic data from AI workloads, reducing wasted compute. It validates and monitors raw data stored in S3, GCS, and ADLS that use open formats such as Iceberg, Delta, and Hudi, enabling governance across data pipelines.

Telmai positions itself in the data observability and data quality space, offering high performance and elastic scaling while aiming to keep cloud costs low. The service runs as a fully managed solution within a customer’s VPC, keeping data in cloud storage and providing secured, zero-copy data handling. In June 2026, Telmai announced the general availability of its workload on Microsoft Fabric, expanding its reach within the Fabric ecosystem.
