Data Labeling & Annotation for ML Training

No machine learning model is better than the training data it's built on, and most teams either burn far too many hours labeling data by hand or trust fully automated labeling that quietly bakes errors into the model from day one. This service builds a hybrid labeling pipeline that uses AI to handle the volume — pre-labeling, flagging low-confidence cases — while your subject-matter experts or our trained annotators review and correct the cases that actually need a human judgment call, producing training data that's both fast to generate and genuinely high quality. We set up the labeling guidelines, inter-annotator agreement checks, and quality sampling so you can trust the resulting dataset rather than hoping it's good enough. It solves the real chokepoint in most ML projects: not the model architecture, but the unglamorous work of getting enough correctly labeled data to train it on.

How We’d Approach This

A clear, staged plan — not a black box

  1. 1

    Define labeling guidelines and taxonomy with your team, including the edge cases that cause the most disagreement

  2. 2

    Pilot the hybrid AI-plus-human labeling workflow on a sample batch, measuring inter-annotator agreement and AI pre-label accuracy

  3. 3

    Review disagreement cases and guideline gaps with your team, refining instructions before scaling to full volume

  4. 4

    Run the labeling pipeline at production volume with ongoing quality sampling and a feedback loop to catch guideline drift
