Coderio vs Harnham: overview
Coderio
Coderio was founded in 2017, is headquartered in Miami and employs around 220 people, mainly in Latin America. It supplies individual engineers or fully managed squads, which it says it can assemble within seven days, in time zones that match U.S. teams. Its AI/ML hiring page says its engineers have production experience rather than only notebook work. AI is one of several areas, and we found no detail on who runs its technical screens.
Harnham
Harnham has recruited for data and analytics roles since 2006 from London, with offices in the U.S. including New York and San Francisco. It places data engineers, data scientists and ML engineers on contract or permanent terms and runs a graduate training arm, Rockborne. As a recruitment agency, it screens through consultants who specialise in data hiring rather than through practising engineers, and contractors are not managed after placement the way a staffing firm's employees are. That makes it better for permanent hires than for managed augmentation.
