Services and software for producing training data: managed human annotation workforces, self-serve labelling tools, programmatic labelling, and synthetic data generation. The marketplace model and the software-only model both live here, and they are bought in completely different ways.
What to compare
Work out first whether you want a managed service or a tool you staff yourself. Check domain expertise if the work needs it, because general crowd labelling and expert annotation are separate products with separate price tags. Then compare quality-control mechanisms, throughput, and where the data is allowed to be processed, which is often the binding constraint.
