Strider vs Harnham: overview
Strider
Strider was founded in 2021 by Neal Kemp and Nicole Barra Conde and is registered in Delaware, connecting U.S. companies with remote developers in Latin America. It covers sourcing, vetting, onboarding and retention. The company says every candidate is screened for English, background, culture fit and technical skill through role-specific technical and soft-skill assessments. It lists ML engineers among its hiring categories, but its pool is mostly general software talent, so ML-specific depth should be tested in your own interviews.
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.
