Sift is an American technology company that provides a unified observability platform for telemetry and sensor data generated by mission-critical hardware systems. Founded in 2022 by former SpaceX engineers Karthik Gollapudi and Austin Spiegel, the company is headquartered in El Segundo, California.[1]
Sift’s platform enables organizations to ingest, store, visualize, and analyze high-volume, high-cardinality machine data without requiring extensive custom software development. Its solutions are designed specifically for industries operating complex hardware systems, including aerospace, defense, transportation, robotics, and energy.
History
[edit]Sift was founded in 2022 by Karthik Gollapudi and Austin Spiegel, both of whom previously held engineering leadership roles at SpaceX. Gollapudi led development on human-rated spacecraft software, while Spiegel managed telemetry systems and Starlink manufacturing innovations.[2]
In November 2023, Sift announced a $7.5 million seed funding round. In June 2024, the company raised an additional $17.5 million in a Series A funding round led by GV (formerly Google Ventures), bringing total funding to $25 million.[1]
Platform and Services
[edit]Sift’s unified platform is purpose-built for modern hardware telemetry and operational observability, addressing challenges such as:
- Managing extremely high-frequency, high-cardinality telemetry streams
- Enabling real-time monitoring, anomaly detection, and root cause analysis
- Creating collaborative review and certification workflows
- Building detailed hardware genealogy and lifecycle traceability
Key offerings include:
- Sift Observability: A no-code platform for engineers to visualize, query, and analyze telemetry without building custom tooling.
- Sift Storage: A telemetry-native backend optimized for the storage, indexing, and querying of massive sensor datasets.
- Rule-Based Anomaly Detection: Customizable alerting and anomaly identification based on mission-specific criteria.
- Hardware Genealogy and Lifecycle Traceability: Tools to map the operational history and relationships of hardware components across missions and time.
- Forward Deployed Engineering: Embedded technical teams that help customers integrate Sift’s platform with minimal disruption.[3]
Applications
[edit]Organizations use Sift to:
- Operate and scale satellite constellations
- Accelerate root cause analysis during hardware development
- Monitor autonomous and robotic systems in real time
- Support compliance and mission certification
- Replace ad hoc telemetry visualization and analysis tools
Customers
[edit]As of 2025, Sift’s customers include:
- JetZero — Aerospace and defense aviation
- K2 Space — Satellite and spacecraft operations
- Astrolab — Planetary mobility and lunar exploration
- Parallel Systems — Autonomous rail transportation
- Reliable Robotics — Autonomous aviation technology
