About Scale AI

Scale AI is a full-stack AI infrastructure company whose core capability is accelerating the development and deployment of AI systems through high-quality training data, model evaluation, and enterprise AI application tooling. The company's data engine — which combines proprietary annotation tools, quality assurance pipelines, and a global workforce of human labelers — has produced training datasets for some of the most capable AI models in existence, including those used by OpenAI, Google, and Meta. Scale's enterprise products extend this capability to allow organisations to fine-tune foundation models on their own proprietary data using Scale's infrastructure. Scale AI's enterprise offering, Scale Donovan and Scale Spellbook, enables large organisations to build, test, and deploy LLM-powered applications with structured prompt management, model comparison, evaluation harnesses, and integration tooling. Scale Donovan is specifically designed for defence and intelligence applications, providing AI-powered decision support with FedRAMP High authorisation and IL5/IL6 compatibility for US government use cases. This makes Scale one of the few AI companies operating at the highest tiers of US government data security classification. For commercial enterprise customers outside the defence sector, Scale offers data labeling services for computer vision, natural language processing, and multimodal AI tasks, along with Scale GenAI Platform for enterprise LLM application development. The platform supports RLHF pipelines that allow organisations to align foundation models to their specific domain requirements and safety standards — a capability increasingly required by financial services and healthcare regulators who expect AI models to be validated against domain-specific criteria. Data security and compliance are foundational to Scale's business model, given its work with the most sensitive government and commercial datasets. Scale holds FedRAMP Moderate and FedRAMP High authorizations, SOC 2 Type II certification, and ISO 27001 certification. Customer data is isolated per project, with strict access controls on human annotators, cryptographic audit trails, and configurable data residency. On-premise deployment is available for customers with data sovereignty requirements that preclude cloud processing. For compliance professionals evaluating AI development tooling, Scale AI represents a rare combination of enterprise capability and government-grade security posture. Its breadth of certifications, support for on-premise deployment, and track record with regulated government and commercial customers make it a strong candidate for organisations building AI systems that must meet stringent data handling, bias evaluation, and model governance requirements.
