SuperAnnotate Tech Stack

Human-data annotation and evaluation platform for training frontier AI models

Software Development San Francisco, California 51–200 employees Privately Held

SuperAnnotate pairs a managed expert workforce with its own tooling for annotation, model evaluation and RL workflows. The stack mixes a TypeScript/Next.js and Node.js product layer on AWS (Lambda, RDS, CDK, Terraform) with OpenAI, Anthropic and Qwen models, pointing to LLM-assisted labeling. Repeated pain points center on annotation bottlenecks, contractor productivity and QA, so delivery operations, not software alone, are the scaling constraint.
