Zstate delivers RLHF training data, SFT datasets, and evaluations built by credentialed specialists — plus the engineering team to take your models into production.
The industries with the highest stakes — healthcare and financial services — require judgment that commodity annotators simply don't have.
Most data vendors stop at delivery. We built the systems — so we know what good data actually produces.
Expert-annotated training data, SFT datasets, preference data, and evaluations — built by domain specialists who understand what they're labeling.
Production-grade agentic systems for healthcare and financial services — AI-native architecture built from the ground up to scale.
Two industries. Genuine expertise. Not a generalist shop with a landing page claiming verticals.
