Index.dev vs Vstorm: 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.

Vstorm

Vstorm, in Wrocław since 2017, builds LLM agents and retrieval-augmented systems and lends the same engineers to client teams. Its Clutch profile gives buyers the two numbers most providers hide: an hourly band of $100 to $149 and a $10,000 minimum project. The score from verified reviews is 4.9. With 10 to 49 people, it can supply one or two engineers, not a department, and its work is concentrated on agents rather than classic ML.
