StackMatch Editorial verdicts

Bylined · No vendor influence
MercorCAUTIOUS-BUY
The AI labs hire here for a reason

Mercor matches engineers and AI specialists to roles via AI-conducted interviews. The OpenAI/Anthropic/Scale customer base validates the model for AI-adjacent talent; the broader engineering placement value prop is less proven.

Choose Mercor if...

AI labs and modern tech companies hiring specialist engineering and AI training talent at scale; teams that need pre-vetted contractors quickly.

Avoid Mercor if...

Traditional enterprise hiring with strict compliance requirements; non-technical roles; companies with mature in-house recruiting they want to amplify (Eightfold or hireEZ may fit better).

Choose 15Five if...

Tech and knowledge-work teams (25–1,500 people) that want a lightweight weekly performance rhythm without heavy review processes.

Avoid 15Five if...

Large enterprises with formal HR-led review processes (Lattice or Workday Talent) or hourly workforces (not the use case).
