## About Sift
Sift is a telemetry platform for teams building mission-critical machines, the rockets, satellites, autonomous vehicles, and defense systems whose sensor readings have to be trusted. It brings every channel of test and flight telemetry into one timeline, runs automated checks on every test, and surfaces anomalies while there is still time to act. Sift is the data layer itself, not a dashboard sitting on top of someone else's database, which is how it holds production-scale volume at nanosecond precision (one-billionth-of-a-second resolution). Engineers use Sift for flight test data analysis, hardware-in-the-loop testing, automated validation and verification on hardware telemetry, real-time fleet monitoring, time-series analysis, and root cause analysis. It ingests from test stands, flight systems, and automated runs in formats like CSV, ULOG, MCAP, TDMS, and MDF, and runs in the cloud, in a private cloud, in classified environments, or fully airgapped. Teams including K2 Space, CX2, Reliable Robotics, and Parallel Systems build on Sift. K2 Space scaled from 10 megabytes of telemetry a year to terabytes a day on the platform, and CX2 cut flight analysis from days to hours.
