Vstorm vs Data Science UA: overview
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.
Data Science UA
Data Science UA grew out of a 2016 data science conference in Kyiv and now runs recruiting, outstaffing and AI consulting, with a legal base in London. It offers two ways to buy. You can pay a recruiting fee for a permanent hire, which it says takes two to four weeks on average, or take the engineer on monthly outstaffing terms first. Its AI community, quoted at 10,000 to 30,000 people, gives it reach. Screening is done by recruiters, so plan your own technical interview.
