Vstorm vs Go Fractional: 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.
Go Fractional
Go Fractional was founded in 2021 and is based in New York. It matches companies with experienced professionals who work part-time, across engineering, product, marketing and other functions, and it has dedicated pages for hiring fractional AI developers and engineers. It says most companies are matched and onboarding within three days. Fractional work is the whole model here, not an add-on, so it suits buyers who need senior judgment a few hours a week. It is less suited to buyers who need several engineers writing code full-time.
