What Labelbox is

Labelbox provides tools and services for AI training data, reinforcement learning environments, evaluations, and enterprise agent workflows. Its current offering includes Recursion, a platform for enterprises to run fleets of agents across connected apps. Recursion work can start from schedules, alerts, events, or API calls; agents can plan jobs, run specialist agents in parallel, use sandboxes, and return graded results with evidence. Shown integrations include Slack, GitHub, Linear, Salesforce, Databricks, Google Drive, Box, and Jira. For model post-training, Horizon offers reinforcement learning environments and evaluations focused on reasoning, tool use, and computer use. Labelbox Annotate provides more than 10 editors for multimodal chat, LLM evaluation, prompt and response generation, computer vision, and natural language processing. Expert labeling services cover tasks such as RLHF, supervised fine-tuning, multimodal LLM evaluation, preference ranking, red teaming, and coding and AI agent tasks. Labelbox says its expert network spans over 200 domains and more than 30 languages. A guide states that free-tier organizations receive 10,000 free Labelbox units before the card on file is charged. The company was founded in 2018 and is headquartered in San Francisco.
