Sift Stack, Inc. is a software company founded in 2022 that builds observability tooling for hardware sensor data. Its platform, Sift, is a unified observability system designed for hardware telemetry, converting messy sensor data into a structured, shareable and trusted source for analysis. The software supports automated data review and real-time anomaly detection, and provides basic insights without requiring users to write code. The company targets organisations working with modern machines that generate terabytes of telemetry data.

The platform serves customers including K2 Space, Astranis, Astrolab and JetZero. Sift Stack operates in the aerospace, defense, robotics, spaceflight and autonomous-vehicle sectors. Its technical work spans hardware telemetry observability, sensor data analysis, real-time anomaly detection, automated data review, telemetry data processing and data infrastructure.

The company was founded by former SpaceX engineers who worked on the Dragon, Falcon, Starlink and Starship programmes. Its stated culture is engineering-first - built by engineers, for engineers - with an emphasis on mission reliability and engineering efficiency, including the elimination of tool juggling in everyday work.
