Scale AI

Scale AI operates as a primary infrastructure provider for artificial intelligence, headquartered in San Francisco since its inception in 2016. The company began by refining data annotation techniques before expanding into a comprehensive suite of tools for labeling, evaluating, and aligning machine learning models. Its operational model depends heavily on a global network of human annotators managed through subsidiaries like Remotasks and Outlier to handle tasks ranging from computer vision to large language model training.

The organization serves a wide array of high-stakes clients including Google, Microsoft, Meta, General Motors, and various government entities such as the U.S. military. A significant shift occurred in mid-2025 when Meta Platforms acquired a 49% stake for over $14 billion. This investment coincided with the departure of co-founder Alexandr Wang to join Meta, leading to Jason Droege assuming the role of CEO.

Recent developments highlight the company's continued expansion within the hardware ecosystem. In October 2026, Scale AI partnered with NVIDIA and Cisco to deploy new pluggable optics designed specifically for their data processing facilities. These collaborations aim to improve throughput for massive datasets while maintaining the rigorous safety standards established by the Safety, Evaluation and Alignment Lab. [edit]
