HFlow

HFlow is an open source SDK designed for building scalable multimodal data pipelines in robotics and physical AI applications. It enables users to define custom transforms, checks, labels, and enrichments while handling orchestration, storage, versioning, and provenance tracking.

The platform provides data quality inspection and reproducibility features, allowing teams to understand how datasets were constructed. Built by Hebbian Robotics, HFlow is part of Y Combinator's Summer 2026 batch.
