Real-world data is the competitive edge in AI.
HumanSignal is a human data partner for companies building AI models and products. Our customers ship better AI, faster, because we partner with their researchers from real-world data creation to annotation to delivery.
We design and create datasets from scratch, recruit and manage the domain experts who evaluate model output, and run everything through our own platform, Label Studio, the open-source standard for data labeling and evaluation, used by over 1 million practitioners worldwide.
We specialize in the operationally complex: real-world data collection, multimodal pipelines, and multi-step workflows. Advanced ML and AI teams use our enterprise platform to run their own data factories, and our services team to extend their reach where in-house capacity runs out.
If you want to do work that materially shapes how the next generation of AI products gets built, we'd love to talk.
Earn up to $500 for a four-hour session performing unscripted, improv-style scenes. HumanSignal is recruiting improv performers, voice actors, and live entertainers to take part in a paid research study. We record people doing everyday tasks and talking naturally so that researchers can study and improve how AI understands real human behavior. If you can hold a scene, think on your feet, and move and talk naturally without a script, you can do this work.
We welcome performers of all backgrounds and experience levels. A wide range of voices, speech patterns, and physical presence makes the research more representative of the real world.
Every participant signs a plain-language research agreement before any recording. It states exactly how your recordings are used, and you can ask us anything about it before you commit.

HumanSignal enables data science teams to build AI models with their company DNA. With the emergence of generative AI, it’s more important than ever to build highly differentiated models by guiding foundation models with proprietary data and human feedback. Creators of Label Studio, the most popular open source data labeling platform, HumanSignal enables data scientists to develop high quality datasets and workflows for model training, fine tuning and continuous validation.
Today, the Label Studio open source community has more than 250,000 users who have collectively annotated more than 100 million pieces of data. Label Studio Enterprise is available as a cloud service with enhanced security, automation, quality review workflows, and performance reporting, used by leading data science teams including Bombora, Geberit, Outreach, Wyze, and Zendesk.
