Go Fractional vs Neurons Lab: 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.

Neurons Lab

Neurons Lab was founded in London in 2019 and keeps a small core staff while drawing on a distributed network of more than 500 engineers, according to its site. That arrangement makes it easy to buy a specialist for a short stretch or part of each week, which an employer-only model makes harder. Its clients include banks and insurers, and it holds an AWS generative AI competency. Continuity is the trade-off, because network members are not employees.
