Once an AI recruiting marketplace, it is now largely a staffing engine placing doctors, lawyers and scientists with AI labs, paying its expert network over 2 million dollars a day. Employers pay around a 30 percent placement fee; joining as talent costs nothing. The San Francisco startup hit a 20 billion dollar valuation in July 2026, with contracts and data handled from the US.

Ideal for HR teams replacing gut-feel screening with evidence, especially where the EU AI Act is raising the bar on fair, explainable hiring.
Why choose TestGorilla over Mercor?
The decisive argument is data jurisdiction. Mercor is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
TestGorilla removes that overhead. As a Netherlands-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
