About Labelbox
Labelbox is an AI data factory platform that provides the software and services organizations need to create, manage, and iterate on high-quality training data for enterprise machine learning applications. Founded in 2018 by Manu Sharma, Brian Rieger, and Dmitry Petrov in San Francisco, Labelbox has raised approximately $189 million in total funding and achieved unicorn status following its $110 million Series D in January 2022 led by SoftBank Vision Fund.
Labelbox's platform enables enterprises to label images, video, text, and documents; manage annotation workflows across internal and external teams; and integrate with ML pipelines from training through production. The company serves Fortune 500 companies and major U.S. government agencies — including a landmark $950 million U.S. Air Force JADC2 contract awarded in 2022, one of the largest AI data contracts in history. In 2024, Labelbox partnered with Google Cloud to offer LLM human evaluation services, and in February 2026 it acquired Upcraft to expand its platform capabilities. Labelbox employs approximately 144 people.
Labelbox's Series D was led by SoftBank Vision Fund with participation from Databricks Ventures, Andreessen Horowitz, First Round Capital, Gradient Ventures (Google's AI fund), Kleiner Perkins, B Capital Group, and Lift Ventures — a deep bench of strategic AI and enterprise software investors that validates Labelbox's position at the center of the AI training data market.
