## Overview
AIxBlock provides enterprise-grade training data for speech recognition and large language models. The platform offers comprehensive services including speech collection, transcription, dialogue annotation, RLHF-style feedback, and ready-to-license call center audio datasets spanning over 100 languages. The company operates a global network of professional contributors and has served Fortune 100 companies for seven years.

AIxBlock distinguishes itself through data sovereignty guarantees—for custom collection projects, clients can connect their own storage directly, and the company never stores copies of collected data. This approach eliminates resale risks. The platform includes multi-layer contributor verification and layered quality controls with consensus validation, audits, and validation loops. Additionally, AIxBlock offers a self-hosted platform for AI development, allowing organizations to deploy on their own infrastructure with a data engine, training capabilities, and GPU marketplace integration.

One limitation is that the tool requires direct engagement and consultation for most custom projects rather than offering self-service pricing models, necessitating sales calls to understand specific costs.
