Rerun

Rerun (operating at rerun.io) is a data visualization platform engineered for physical AI teams. Founded in 2022 by Nikolaus West, Emil Ernerfeldt, and Moritz Schiebold, and headquartered in Stockholm, Sweden, Rerun bridges the gap between raw multimodal data and actionable insights. Unlike traditional tools like ROS rosbags, which are niche to robotics, Rerun offers a unified data layer for visualizing complex, time-series data—including 2D/3D imagery, text, tensors, and time-series metrics—across computer vision, robotics, and autonomous systems. Under the hood, its SDK enables real-time ingestion, querying, and streaming of multi-rate datasets, allowing engineers to debug, review, and extend workflows with custom annotations. This empowers researchers and developers to iterate faster on physical AI projects, from fleet logs to human-data rigs, while reducing the friction of disparate data sources. Backed by a privately held structure, Rerun’s revenue reached $7.5M in annual recurring revenue (ARR) as of 2025, reflecting its growing adoption in AI infrastructure.
