upstream-data

The standard for evaluating healthcare AI.

Compare Claude, GPT-4o, and Gemini against synthetic claims with deterministic ground-truth payer behavior. Train, test, and prove your RCM agents without ever touching PHI.

Zero PHI. Architectural guarantee.

Upstream Data synthesizes claims from statistical priors and payer-behavior rule models. No real patient records enter the pipeline — ever. The guarantee is contractual and architectural, not just a policy.

Synthesis source

Statistical priors + rule models only

Real data input

None. Zero. Architectural constraint.
