Appen

Appen creates value by helping enterprises build, fine-tune and validate machine learning and generative AI systems without having to assemble their own large-scale data operations. The business combines software infrastructure for annotation and workflow management with human-in-the-loop labour orchestration, data asset creation, and specialist evaluation services. Revenue is generated from platform licensing, usage-based processing, and bespoke enterprise projects for data collection, labelling, testing and compliance-oriented model assessment.

Appen is an Australian public company that provides AI training data, data annotation workflows, and model evaluation services to enterprise AI teams. Its core offering is ADAP, a proprietary platform that combines workflow automation with human oversight for labelling, fine-tuning, evaluation and quality control across text, image, audio, video and 3D data. Beyond software, it also supplies managed data services and specialised datasets for multimodal AI, speech, robotics, autonomy and agentic AI use cases.
