Maki vs Mercor: Which Fits Your Hiring Stack?
Maki and Mercor are built to do different things. Maki positions itself as hiring intelligence end to end (AI agents, assessments; EU/GDPR angle). Mercor positions itself as AI-vetted talent marketplace (now focused on AI-lab expert talent). The practical difference shows up in four places: whether the tool sources candidates, what an interview actually looks like, what evidence sits behind a score, and whether pricing is published. Each section below is drawn from what the two companies state publicly. The Cognitive publishes this comparison and competes with both.

Does Maki or Mercor source candidates?
| Half of the pipeline | What it has to deliver | Maki | Mercor |
|---|---|---|---|
| Sourcing (outbound) | Candidates who have not applied, with contact details that resolve | Not offered | A marketplace — you hire from their pool |
| Screening (evaluation) | A judgement about ability, with evidence behind it | Structured tests and assessments | Vetting inside their own pipeline |
| Evidence | Something a rejected candidate or an auditor can be shown | Test scores | Their vetting, not yours |
| Cost visibility | A number you can size before a sales call | Published, EU/GDPR positioned | Marketplace fees, not software pricing |
Candidate sourcing is the outbound half of recruitment: searching for people who have not applied, checking them against the role, revealing contact details and opening the first conversation. Screening is the half after that — deciding which of the people in front of you is worth a hiring manager's hour. Tools in this category tend to be built for one half or the other, and a shortlist that mixes them up buys the same half twice.
Maki's published position on sourcing is: Not offered. Mercor's is: A marketplace — you hire from their pool. On the interview side, Maki states: Structured tests and assessments; Mercor states: Vetting inside their own pipeline. Where a row reads "not stated publicly", treat it as an absence of a public claim rather than as evidence the capability is missing — ask in the demo.
Choosing between them
- Pick Maki if your bottleneck matches its strength: Large skills-test library (150+) and science-based assessment approach
- Pick Mercor if your bottleneck matches its strength: Pioneered AI-interviews-at-scale for marketplace vetting
- If pricing visibility matters to your process, compare the two rows above before booking either demo — one of these vendors publishes a number and the other may not.
- Neither choice is permanent. The row that usually decides it is "evidence behind a score", because that is the one your hiring managers argue about 6 months in.
A third option: cover sourcing and interviewing in one pipeline
Most shortlists that include Maki and Mercor are really choosing between two halves of the same problem — finding candidates and evaluating them. The Cognitive covers both: candidate sourcing across ~900M profiles with contact details enriched from 30+ sources, then a live, two-way AI video interview with a real face and voice. Every rating on the scorecard ties back to a quote and a timestamp, and it works inside the ATS you already run rather than replacing it.
