The horizontal approach
Thousands of generalist annotators. One-size-fits-all tooling. Quality that's “good enough” for demos but breaks in production. Domain knowledge treated as optional.
The iStarai approach
Curated specialists per vertical. Custom QA per domain. Tooling built around your ontology. Every layer adds depth, not breadth. Your moat, engineered.
From zero to production-grade.
Six phases. Each one eliminates a category of failure. No shortcuts.
Niche Validation
We study your vertical. Ontology review, edge-case mapping, annotator skill requirements. No generic onboarding.
Zero-Code Ops Setup
Custom labeling interface built around your schema. No SDK integration. Upload data, define taxonomy, start.
Pilot Insanity
500 samples annotated with production-grade rigor. You compare against your internal team. We win or walk away.
AI-Assisted QA
Model-in-the-loop pre-annotation. Human verification. Consensus scoring. Automated drift detection.
Internal Dashboard
Real-time quality metrics. Annotator performance. Cost per label. Full transparency, no black boxes.
Scale Workforce
Expand from pilot to production. Dedicated team scales with your data needs. Same quality, any volume.
The two-person rule.
Every label passes through independent verification. Two domain experts. Zero single points of failure. Consensus-driven truth.
Independent verification with interlocking consensus
