Products

Selected offerings — the AI products recorded here, not the vendor's full catalogue.

• AI Data Platform Platform

  Appen's data platform (ADAP), where automation and human oversight run together to produce expert-validated training data across six lines: frontier alignment, agentic AI, speech and audio, multimodal, physical AI and model integrity.

• MatrixGo Platform

  MatrixGo is Appen China's enterprise data annotation platform, offering image, point-cloud, video, text and speech annotation tools with project management, configurable workflows and AI-assisted pre-labelling, sold as public-cloud SaaS or private-cloud on-premises deployment.

• Off-the-Shelf Datasets Data service Sold on its own

  Appen's licensable catalogue of pre-labeled training data — over 300 audio, image, video and text datasets in more than 80 languages, sold as-is rather than collected to order through ADAP.

• Appen Agentic AI Data service Sold on its own

  Training and evaluation data services for AI agents: task/verifier design, trajectory and failure-mode analysis, golden-trajectory creation, RL environment design, RAG evaluation, and SWE-driven deep evaluation -- verified live with six named sub-services.

• Appen Frontier Alignment Data service Sold on its own

  Produces data services for frontier-model alignment.

• Appen Model Integrity Data service Sold on its own

  Evaluates model factuality, safety and integrity.

• Appen Physical AI Data service Sold on its own

  Collects and annotates training data for physical AI (robotics and embodied-agent) systems.

Total funding

Checked — none published

Listed on the ASX; equity funding history is not the relevant figure for a public company and none is published as a total.

Market cap

Not found · 4 Sep 2026

Market capitalisation is A$290.01M (2026-09-04) — quoted in Australian dollars. This column stores raw USD, and converting would mean choosing an exchange rate this record cannot cite, so it is null rather than a self-made conversion.

Employees

Wikipedia · 4 Sep 2026

Infobox: "1000 (2024)". A 2024 figure, carried as the most recent one published anywhere reachable — appen.com/investors/ publishes results only as downloadable presentations.

Founded

Not found · 4 Sep 2026

The infobox gives 1996, but it is not corroborated on Appen's own site and this record does not carry a founding year on one aggregated infobox line alone.

Revenue

Not found · 4 Sep 2026

A$361.92M trailing twelve months (2026-09-04), again in Australian dollars — same conversion problem as valuation. Wikipedia's US$273.0M is a 2023 figure and three years stale.
