About

Founded in 2023, Mercor uses AI to automate the most time-consuming and bias-prone parts of technical hiring: sourcing candidates, conducting initial technical screenings through AI-powered interviews, and matching engineers and data scientists with roles based on demonstrated skills rather than resume signals.
