HumanSignal

We help data science teams build AI models using their own data and human feedback. We offer tools and services to create high-quality datasets and workflows for training, fine-tuning, and continuously validating models.

Our main product, Label Studio, is an open-source data labeling platform used by over 350,000 people. Label Studio Enterprise is available as a cloud service or on-premise. It includes stronger security, automation, quality review tools, and performance reports. Companies like Bombora, Geberit, Outreach, Wyze, and Zendesk use it. The platform handles complex data types like audio, video, sensor outputs, and timeseries data.

We also offer Data Services. Our expert annotators, data scientists, and project managers work with clients to create custom datasets. These services include data collection, creating onsite workforces, expert domain annotation, evaluations, red teaming, and fine-tuning. We ensure secure, compliant workflows with clear human oversight.

Our mission is to help AI learn from human knowledge. We believe AI can’t solve humanity’s biggest problems without human insight. We help data scientists use data to train ML/AI models to make predictions.

Our core values are:

• Open Source: We make data-centric AI accessible to all data scientists through open-source software and community collaboration.
• Domain Expertise: We believe internal teams and domain experts should annotate and curate training data. This helps reduce bias through collaboration and automation.
• Community: We encourage sharing knowledge and experiences to speed up the data-centric AI movement.
