A workforce that levels up.Quality that compounds.

Annotation Platform

Annotation is more than labeling data. It’s about building a workforce that continuously learns, improves, and produces higher-quality data over time.

In Production

What We Run Today

An operating annotation business — not a concept.

Global, in-house

Multi-country, multi-language teams. Full-time, in-house annotators — no outsourcing, no anonymous crowd.

Specialist channels

Dedicated teams for egocentric robotics video — hand tracking, object tracking, and action labels, frame by frame.

Built for scale

20+ global sites, one QA standard.

Methodology

Quality is designed into the process —not inspected in afterwards.

  1. Consensus Labeling

    Multiple annotators, one truth: disagreements surface instead of shipping.

  2. Gold-Standard Checks

    Known-answer tasks seeded through every batch measure real accuracy continuously.

  3. Arbitration

    Experts resolve the hard disagreements — and their rulings become the standard for the whole team.

  4. 1:5 QA Ratio

    One quality lead for every five annotators, on every project.

The thesis

Quality depends on the people behind the data.

The best annotators produce dramatically better data than the average. Most platforms treat every contributor the same.

Building

Not a task management platform.An intelligence layer for human expertise.

Plenty of platforms manage tasks. Thoth is building the intelligence layer around the people — matching each item to the right expert, protecting quality before it slips, and lifting the whole workforce toward its best.

Building

Match

We're building the platform that routes every task to the people most likely to produce the highest-quality annotations.

Building

Protect

We're building the platform that detects fatigue and quality drift before they affect the dataset.

Building

Elevate

We're building the platform that learns from the best annotators and elevates the whole workforce.

The Workflow

The Workforce Intelligence Loop

Every annotation strengthens the platform. Match expertise, monitor quality, and continuously improve workforce performance with every completed task.

Our Mission

Our Mission

“Build an annotation platform where quality is designed into each task, expertise scales across the workforce, and every completed project makes the next one better.”
