HumanSignal is a San Francisco-based software development company that helps data science teams build AI models aligned with their own data and human feedback. As generative AI evolves, the firm emphasizes differentiating foundation models by guiding them with proprietary data and human input. It is the creator of Label Studio, a widely used open source data labeling platform, and offers Label Studio Enterprise as a cloud service that adds security, automation, quality review workflows, and performance reporting for teams including Bombora, Geberit, Outreach, Wyze, and Zendesk. The Label Studio ecosystem has grown to more than 250,000 users who have collectively annotated over 100 million pieces of data. In late 2025, HumanSignal expanded its data capabilities through the acquisition of Erud AI and the launch of Frontier Data Labs for novel data collection.
