October 2025 Summaries

Headless BI, a modern approach to business intelligence, offers a flexible and powerful way to manage data by separating the semantic layer from the presentation layer, allowing metrics, joins, and calculations to be consistently defined and reused across various visualization tools, dashboards, or apps. Unlike traditional BI tools that bundle everything together, Headless BI enables data to be more dynamic and adaptable, providing teams with confidence and consistency in their analytics stack. This method, championed by Preset, ensures that key metrics are defined once to maintain a single source of truth, allowing data to be integrated seamlessly into different platforms through APIs and integrations. It supports scalability and evolution of the data stack without major overhauls, making it compatible with modern technologies like Snowflake, BigQuery, and dbt. By offering control over data definitions and ensuring they are not fragmented, Headless BI empowers businesses to scale analytics efficiently while maintaining data integrity and consistency.
