Scale AI

Scale AI was founded in 2016 by Alexandr Wang and Lucy Guo, building infrastructure and workforce management systems for data labeling and annotation, the often labor-intensive process of tagging and categorizing raw data, such as identifying objects in images or evaluating the quality of AI-generated text, that is necessary to train and evaluate machine learning models, a critical but historically underappreciated part of the AI development pipeline that Scale AI helped professionalize and scale considerably as AI model training data needs grew dramatically. Scale AI built particularly strong relationships with major AI labs and technology companies as customers for its data labeling and evaluation services, including significant work supporting the training and evaluation of large language models through human feedback and evaluation processes, positioning the company as important infrastructure supporting much of the broader AI industry's model development pipeline regardless of which specific AI lab's models it was helping to train or evaluate. In a significant 2025 transaction, Meta invested approximately $14.3 billion for a 49% stake in Scale AI, and the company's CEO and co-founder Alexandr Wang joined Meta to lead its newly formed Meta Superintelligence Labs division, a deal structured to give Meta substantial access to Scale AI's technology and leadership talent while Scale AI continued operating with new leadership, an outcome that led to Scale AI's removal from some private company rankings given the transaction's unusual majority-stake-without-full-acquisition structure. Scale AI had raised substantial venture funding from investors including Founders Fund and Tiger Global prior to the Meta transaction, reaching a valuation exceeding $29 billion.
