AIxBlock
AIxBlock gives enterprise AI teams a sovereign data platform for collecting, annotating, and licensing training data across speech, audio, and text modalities. The company delivers speech transcription in 100+ languages, RLHF preference datasets, environmental audio libraries, and call center recordings spanning hundreds of thousands of hours. A self-hosted deployment option runs the full data engine on your infrastructure so sensitive data never sits on AIxBlock servers.
Scale AI and Appen store client data in their own cloud, which creates compliance friction for regulated industries. AIxBlock connects custom collection projects to your storage from day one and cannot resell data it never holds. The self-hosted platform includes annotation tooling, model training, and a GPU marketplace deployable on-premises or in a private cloud with GDPR and HIPAA compliance built in.
AIxBlock serves Fortune 100 companies including Oracle, AWS, Apple, and Uber across banking, healthcare, government, and defense. Developer teams building speech recognition, noise detection, or LLM fine-tuning models use AIxBlock for multilingual data collection with multi-layer contributor verification and consensus-based quality controls.
