Index.dev vs Tribe AI: overview

Index.dev

Index.dev, legally Index Soft Limited, is a London talent platform that its job ads date to 2019. Its buying terms are the clearest of any network here: every placement carries a 30-day trial with a full refund if the match fails. You can contract one engineer, build a dedicated offshore team or hire someone directly. The main pool of more than 30,000 engineers sits in Latin America and Central and Eastern Europe, and a separate AI unit supplies Master's and PhD-level people for fine-tuning and retrieval work. Vetting runs through five stages with human reviewers.

Tribe AI

Tribe AI, founded in New York in 2019, has a core team of about 35 and a network of more than 300 machine learning engineers, data scientists and strategists. You buy its people by the project or part-time, which suits a defined problem such as an architecture review or a short proof of concept. Many network members come from large tech companies and hold other roles, so it is not the place to buy a full-time engineer for a year.
