Bottom line
Braintrust is a freelance talent marketplace plus an AI screening product. Employers pay a published 15% fee on talent payments, and talent pays nothing. It fits companies hiring contract engineers and specialists that want a transparent fee instead of a staffing agency markup.
Stands out for: Braintrust publishes its 15% client fee, which is rare among vetted talent networks. The same company sells AIR, an AI voice interviewer that runs thousands of screens a day and syncs ranked results to Greenhouse, Lever, Workday, iCIMS and SmartRecruiters.
Watch out for: The site now spans three products, including Nexus for operations automation, so the marketplace can be hard to find. The 15% fee also applies to direct hires and conversions within six months, and EOR services cost extra.
