Svitla Systems vs Harnham: overview
Svitla Systems
Svitla Systems was founded in 2003 by Nataliya Anon and is based in Corte Madera, California, with Miami as a second U.S. base. It reports more than 1,300 employees, roughly 500 in Latin America and 500 in Ukraine, Poland and Romania. Its staff augmentation work gets good reviews for how well engineers fit into client teams, and its 2026 job ads seek agent and RAG engineers. Some Clutch reviewers say its vetting of senior engineers could be better, which matters for ML roles where seniority is the whole point.
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.
