Rerun builds an open-source multimodal data stack and cloud platform purpose-built for "Physical AI" workflows, managing video streams, 3D scenes and tensors for robots, drones and cars. Its tools enable visual debugging so developers can trace agent movements and diagnose failures by importing real-world sensor data for spatial visualization and analytics. The platform has been incorporated into other open-source projects from companies including Meta, Google, Hugging Face and Unitree. The team includes veterans from Apple, AWS, Meta, Unity, Zenly and Zipline; CTO Emil Ernerfeldt is the creator of egui, a major open-source Rust GUI framework. Rerun positions its stack to reduce friction between traditional robotics tools and modern machine learning, aiming to accelerate deployments and a potential data-driven flywheel for model improvement. Financially, the company announced a $17M seed and has raised $20.2M in total to date. Rerun is a Stockholm-based AI platform that helps developers bring AI products into the physical world. The company visualizes complex software over space and time to make it intuitive for humans. It says this approach helps large teams move faster and enables small teams to get off the ground. Rerun targets deployment in sectors such as autonomous vehicles, robotics, agriculture, manufacturing, augmented reality, and medical imaging. The startup raised $3.2 million to hire a founding team of developers to build the first version of its product. Founders are Emil Ernerfeldt, Nikolaus West, and Moritz Schiebold.
