Company overview

Sifflet is the business-aware data observability platform that moves data teams from reactive firefighting to proactive decision intelligence. Powered by an intelligent system of AI agents—Sentinel, Sage, and Forge—Sifflet autonomously detects anomalies, diagnoses root causes, and suggests code resolutions. By enriching technical alerts with full-stack lineage and downstream business usage, Sifflet allows data engineers and leaders to prioritize incidents based on business risk rather than technical severity. Trusted by industry leaders like Carrefour, BBC or Penguin Random House, Sifflet bridges the gap between data quality and business impact, ensuring your data is always safe for executive decisions and AI consumption.
