Sift, a company building an intelligence layer for mission-critical machines, has successfully closed a $42 million Series B funding round. Led by StepStone, with participation from GV and others, the investment brings Sift's total funding to $67 million. This capital will accelerate the development of essential AI infrastructure for hardware systems across the space, defense, and manufacturing sectors.
Addressing a Critical Infrastructure Gap
A fundamental gap exists between the advanced capabilities of artificial intelligence and its ability to operate physical machinery. Modern systems like rockets and autonomous vehicles generate millions of data points per second from numerous sensors. Without a proper framework, this raw data remains unstructured and incomprehensible to AI algorithms.
Sift's platform directly addresses this challenge by automatically transforming complex sensor data into a structured and queryable format. This process creates a unified data layer that both engineers and AI systems can effectively utilize. The technology enables AI to interact with hardware as seamlessly as it does with software code.
From SpaceX to an Industry-Wide Solution
The company was founded by SpaceX veterans Karthik Gollapudi and Austin Spiegel, who experienced this problem firsthand. While building monitoring systems for rockets, they recognized that the hardware industry lacked the sophisticated observability tools common in software development. This insight inspired them to create a solution tailored for complex physical systems.
By serving as a single source of truth for audio, video, logs, and telemetry, Sift empowers engineering teams. It allows them to diagnose anomalies faster and validate designs against real-world performance data. This unified visibility is critical for scaling operations from single prototypes to entire fleets of machines.
Driving Innovation Across Key Sectors
Sift has already gained significant traction and is trusted by leading companies in the aerospace and autonomy industries. Its client roster includes ULA, Astranis, Parallel Systems, and several undisclosed enterprise defense programs. This adoption highlights the platform's effectiveness in demanding, high-stakes operational environments.
Neel Kunjur, Co-Founder and CTO at K2 Space, emphasized the platform's importance for managing large satellite constellations. He noted that Sift will be critical for handling enormous data volumes and automatically flagging anomalies. This capability helps close the design loop by using operational data to inform future improvements.
Fueling Future Growth and Expansion
The new capital injection is earmarked for significant strategic growth initiatives. Sift plans to expand its engineering team to enhance its platform's capabilities further. The company will also relocate to a larger headquarters in Marina Del Rey to accommodate its growing workforce.
With this investment, Sift intends to nearly double its team from its current size of 70 employees. This expansion is crucial for scaling its platform to meet the rising demand from organizations deploying AI-controlled hardware. The funding positions Sift to solidify its role as a foundational technology provider in the industry.
Sift's $42 million funding round marks a significant milestone, highlighting the critical need for advanced data infrastructure in the hardware sector. The investment validates the company's vision of bridging the gap between physical machines and artificial intelligence. As industries increasingly rely on AI-driven automation, Sift is poised to become the essential intelligence layer for the world's most complex systems.
