Foxglove raises $40M Series B to power the future of Physical AI

Physical AI data and observability platform provider Foxglove announced $40 million in Series B financing, led by Bessemer Venture Partners, with participation from existing investors Eclipse and Amplify Partners.

The San Francisco-based company said it will use the Series B funds to deepen its capabilities in visualization and data management, and to expand its platform to support the entire data lifecycle from initial prototype to global deployments.

A platform purpose-built for Physical AI

Foxglove said that Physical AI is rapidly transforming critical industries such as manufacturing, logistics, transportation, agriculture, construction, aerospace and defense.

Foxglove said it empowers developers in these industries to collect, analyze and learn from the vast quantities of multimodal data required to train and deploy robots. Foxglove’s platform is trusted by tens of thousands of developers, including autonomous lawn mowing organization Greenzie.

“Every Physical AI company faces the same challenge: building a flywheel that lets robots capture and learn from vast quantities of data in complex, real-world environments,” said Adrian Macneil, CEO of Foxglove. “Our mission is to build that infrastructure so our customers can focus on solving unique, domain-specific problems. This funding allows us to expand our platform to support the complete data lifecycle across development, testing and operations.”

Foxglove said that Physical AI places unique demands on data infrastructure: multimodal sensor data, massive datasets, bandwidth-constrained edge environments and the need for precise time‑synchronized analysis.

Foxglove said it addresses these realities end-to-end:

• MCAP: An open-source standard for multimodal logging launched by Foxglove in 2022, which the company said has been widely adopted across the Physical AI ecosystem and included by default with the ROS 2 and NVIDIA Isaac frameworks.
• Data Platform: Storage, search and query of petabyte‑scale robotics data, with flexible deployment options across cloud, on-premises and air-gapped environments.
• Visualization: Interactive analysis that brings together 3D, video, audio, GNSS, time-series and other data modalities into a unified workspace for development and debugging.

“At Bessemer, we believe Physical AI represents the next generational platform shift - as impactful as mobile computing or cloud infrastructure,” said Jeremy Levine, partner at Bessemer Venture Partners. “Foxglove is the clear category leader, building the developer tools and infrastructure stack that every robotics company will rely on. We’re proud to partner with Adrian and his team as they accelerate this industry-defining opportunity.”
