Foxglove.dev builds a platform for robotics teams to visualize, annotate, and collaborate on robot data. It lets users view images and 3D point clouds, draw bounding boxes, assign labels, plan movements, and drill into data with plots or raw message views. Recordings can be uploaded to a private data lake for easy storage, search, and analysis. The tool is designed to help teams develop and operate robots faster by providing a single interface for data review and decision making. Compared with others, Foxglove emphasizes experiencing the world as the robot sees it, supports open-source contributions, and combines visualization with data access and collaboration. Its goal is to accelerate robotics development and reduce time to market while improving incident response and data discovery through an accessible platform and community-driven improvements.

Foxglove Raises $40 Million Series B to Power the Future of Physical AI

Foxglove raises $40 million Series B to power the future of Physical AI. Funding led by Bessemer Venture Partners underscores the critical role of data infrastructure and observability in unlocking robotics at scale. Foxglove, the leading data and observability platform for Physical AI, today announced $40 million in Series B financing led by Bessemer Venture Partners, with participation from existing investors Eclipse and Amplify Partners. Physical AI is rapidly transforming critical industries such as manufacturing, logistics, transportation, agriculture, construction, aerospace, and defense. Foxglove 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, from early-stage startups to industry leaders such as NVIDIA, Amazon, Anduril, Wayve, and Dexterity. "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." "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." A platform purpose-built for Physical AI 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 addresses these realities end-to-end: * MCAP: an open-source standard for multimodal logging launched by Foxglove in 2022, widely adopted across the Physical AI ecosystem and included by default with the popular 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. Foxglove will use its 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, cementing its position as the leading infrastructure platform for Physical AI. About Foxglove Foxglove is building the data and observability platform for Physical AI. From simulated environments to high-stakes production settings, Foxglove provides the observability, data, and developer tools needed to scale autonomy in the real world. Founded in 2021, with alumni from Cruise, Aurora, Amazon Robotics, Stripe, and Coinbase, Foxglove powers hundreds of customers across industries including automotive, aerospace, defense, logistics, agriculture, construction, and consumer robotics.
