Go Fractional vs N-iX: overview

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.

N-iX

N-iX was founded in 2002, lists its registered headquarters in Malta and delivers mostly from Ukraine, Poland and other Central European countries with more than 2,400 engineers. Its 2026 company material sets out three ways to buy: staff augmentation to extend your core team, a managed team for part of a product, or project delivery. ML and data engineers are available under all three. The firm suits enterprise procurement, though AI is a small share of its work and rates are not public.
