Labelbox, founded in 2018 and headquartered in the United States, builds data infrastructure for artificial intelligence teams. Its full-stack platform combines enterprise annotation tools, data labeling services, and an expert marketplace to help organizations produce the training data that modern AI models require. Use cases span reinforcement learning from human feedback (RLHF), model evaluation, and robotics dataset construction.
Central to the platform is Alignerr, Labelbox's expert marketplace and global network of over one million knowledge workers across more than 40 countries. Alignerr supplies specialized, domain-specific training data and elite expert services at scale - work that standard crowdsourcing pipelines are typically ill-equipped to handle.
The company's customer base runs from Fortune 500 enterprises to research labs, and it counts partnerships with more than 80% of leading AI labs in the United States. Labelbox has raised $189 million in funding from investors including Kleiner Perkins, Andreessen Horowitz, and SoftBank Vision Fund.
