Scale AI

Scale AI has built the critical data infrastructure layer for the AI economy — providing the high-quality human-annotated training datasets and evaluation frameworks that make the difference between a mediocre and a frontier AI model. At a $14B valuation, the company's Remotasks platform employs 100,000+ global annotators who label the images, text, audio, and video that teach AI systems to perceive and reason. Scale's RLHF-as-a-service offering was the key differentiator in OpenAI's GPT-4 fine-tuning process and similar work for government defense applications. CEO Alexandr Wang became the world's youngest self-made billionaire at 25, and Scale AI's contract with the US Department of Defense for the Donovan AI platform represents one of the most significant defense technology relationships in the industry.
