Sift provides a unified data platform that ingests audio, video, logs, and high-frequency telemetry and automatically transforms raw sensor data into structured, queryable formats for engineers and AI systems. The platform is used as a system of record by customers including ULA, Astranis, K2 Space, Parallel Systems, and undisclosed enterprise defense programs to diagnose anomalies, validate designs, and maintain fleet-wide visibility. Founded by SpaceX alumni Karthik Gollapudi and Austin Spiegel, Sift aims to enable fleet-scale operations by automating anomaly detection and providing unified observability across thousands of machines. The company has about 70 employees and plans to nearly double its team, relocate to a larger Marina Del Rey headquarters, and expand platform capabilities. Financially, Sift has raised a total of $67 million following its $42 million Series B.
