Problem: AI developers waste 40–60% of project time sourcing, cleaning, and licensing training data, while facing legal risks from copyright violations and quality issues caused by unstructured or overly large datasets. The end of the free scraping era has created a data supply crisis: 42% of business leaders lack sufficient proprietary data for AI training, yet existing marketplaces require weeks of manual negotiation and do not provide standardised AI-ready formats.
Solution: Opendatabay is the AI Training Data Exchange, where developers instantly access licensed, modality-specific datasets - including text, image, audio, video, code, and agentic trajectories - with clear usage rights and proper provenance. Every dataset comes with a commercial or general AI training license, enabling safe and fast deployment for LLM fine-tuning.
