iMerit review: an AI training data provider for expert reasoning data under strict compliance
Answer in brief: iMerit, now an EXL company, is our #12 AI training data provider for labs. For generative AI it supplies expert-led model evaluation, chain-of-thought reasoning data, RLHF, red teaming and alignment. That work runs through iMerit Scholars, which iMerit says has 25,000+ domain experts in 60+ countries, and through the Deep Reasoning Lab in its Ango Hub platform. Its compliance page lists SOC 2 Type 2, ISO 27001, ISO 9001:2015, HIPAA, GDPR and TISAX. Pricing is not public, and the EXL integration may change how accounts are structured.
Bottom line: When your reasoning data touches medicine or other regulated domains, iMerit's compliance stack and curated experts reduce risk.
