Practitioners who evaluate and rank model outputs the way a real professional in that domain would, not just by grammatical plausibility.
Domain specialists who generate and validate training examples with the contextual depth that determines whether a fine-tuned model holds up in production.
Active professionals who surface factual errors and domain-specific edge cases that only a practitioner with hands-on experience would catch.
Verified experts who assess AI outputs against real professional standards, so evaluation performance translates to production performance.
Specialists who author domain-specific Q&A pairs and instruction sets that reflect how real practitioners think and communicate.
Every feature is designed around one principle — the quality of your model is only as good as the quality of the people training it.
From project brief to expert onboarding, Nexus streamlines expert sourcing for AI training, evaluation, and data-focused workflows.

A U.S. research firm needed input from Heads of Operations, Plant Managers, Digital Transformation Leads, and CIOs implementing AI across five industries and three continents, at a volume and consistency that exceeded internal capacity.
Nexus verified 75 domain experts across North America, Europe, and Asia-Pacific using a standardized discussion guide. Localization support applied where needed. Responses clustered by vertical and geography to surface sector-specific patterns.
70+ expert engagements completed across three regions in under three weeks. Structured outputs fed directly into the client's global report, saving an estimated 100 internal hours.

We source experts for the full pipeline: RLHF preference annotation, SFT data generation, adversarial red-teaming, benchmark design, instruction dataset authoring, and ongoing model monitoring.
Most briefs result in matched and verified experts within 24 to 48 hours. Projects requiring highly specific credentials or multi-geography sourcing may take up to 72 hours.
We verify against actual professional records, including clinical licences, bar registrations, and CFA certifications. Self-reported expertise is not accepted.
Every engagement includes NDA execution, MNPI screening where applicable, and domain-appropriate compliance protocols. Additional requirements can be accommodated on request.
Yes. Niche and hyper-specific profiles are a core part of what we do. Our team conducts custom outreach rather than defaulting to database-only matching.
Healthcare and life sciences, finance and investment, strategy consulting, engineering, supply chain, energy, government, and media. Submit a brief if your domain is not listed.
Annotation platforms provide scale. Nexus provides the right person for the task, which matters in domains where getting an output wrong has real professional or regulatory consequences.
