Its services span speech and voice data (collection, transcription, phonetic and emotion annotation), real-world sound and environmental audio for acoustic models, text and dialogue services (conversation annotation, intent and entity labeling, RLHF preference data, LLM fine-tuning datasets), and a large off-the-shelf library of call center audio in accents such as US, India, and the Philippines. Quality is managed through multi-tier QA, consensus mechanisms, blind testing, and layered identity controls including KYC and biometric verification. A key differentiator is a self-hosted platform where clients connect their own storage from day one, so collected or labeled data flows directly to their environment and AIxBlock never retains a copy, removing resale risk for regulated sectors.
With seven years of experience serving Fortune 100 companies and unicorns, EU innovation backing, and ISO 27001 and SOC 2 Type II certifications, AIxBlock targets regulated industries like banking, healthcare, and government. Beyond data, it offers a full AI development platform combining a data engine, model training, workflow automation, and a decentralized GPU marketplace.
