How we count
- We read each company's own public job board every day and count the roles open that day. Duplicate postings count once.
- The order is the number of open roles and nothing else. Ties go in alphabetical order. No company pays to be listed or ranked.
- Badges are free. A badge shows the company's real rank this month, and showing one does not change the list.
- Work at a listed company? You can correct its careers page, logo or countries. A correction does not change its ranking. Correct a company's details
- "New" means roles we first saw in the last 30 days. "Remote" means the posting says remote.
- Left out: companies whose main business is not AI (Krafton, Palantir, Snowflake), and AI data vendors listed on our AI training board (CrowdGen by Appen, DataForce by TransPerfect, Flitto, Voithru).
- A country gets its own page once 10 or more AI companies are hiring there. Companies without a public job board are not counted yet.
