Train Medical AI
—on Day One
Without a Single Real Patient Record
Zero PHI. Zero IRB delays. Zero hospital approvals. QA-certified synthetic clinical datasets — built for AI teams that ship models, instead of governance paperwork.
WITNESS DATA FACTORY™ generates fully synthetic clinical datasets across nine medical domains, evaluates every record through a deterministic rule engine, and packages each batch in audit-ready JSONL with compliance-grade documentation — ready for labeling pipelines, model fine-tuning, and regulatory review on day one.
We don't just claim synthetic purity.
We document it — so your models,
your auditors, and your clients
never have to take it on faith.
