Uvik Software vs Go Fractional: overview

Uvik Software

Uvik Software, founded in 2015 and based in Tallinn with a sales office in Ipswich, sells Python engineers for data, AI and backend work, and it is one of the few providers here whose buying terms you can read before calling. Clutch lists a $50 to $99 hourly band. Squads of three to eight engineers can be scaled up or down on 14 days' notice, and profiles arrive within 24 to 48 hours. All engineers are full-time employees with seven to fourteen years of experience on average. An aggregator mentions a 30-day free replacement, but Uvik's own pages don't confirm it.

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.
