Competitive Landscape

Who Turing competes with, and how they differ.

Scale AI7.6/10

Was the category leader until Meta bought a 49% stake and hired its CEO in June 2025, triggering a client exodus (Google, Microsoft, OpenAI) over neutrality concerns -- the same clients Turing has been courting as a lab-neutral alternative.

M

Mercor8.0/10

Runs the same AI-training-data-plus-vetted-talent model as Turing and is frequently named alongside it as one of the fastest-growing independents picking up business Scale AI lost after the 2025 Meta deal.

S

Surge AI

Bootstrapped RLHF/data-labeling rival that overtook Scale AI in 2024 revenue ($1.2B vs. $870M) and, like Turing, markets itself on lab-neutrality after the Scale-Meta deal.

Eightfold AI7.6/10

Competes on Turing's original line of business -- AI-driven candidate matching for enterprise recruiting -- rather than Turing's newer AI-training-data/evaluations business for frontier labs.
