Harnham
Specialist data and AI recruitment firm placing permanent, contract, and executive talent across the UK, US, and Europe.
Mid-market and larger companies building data science, analytics, AI, or risk-analytics teams that want a niche recruiter rather than a generalist staffing desk.
Buyers that only need a software sourcing tool, a self-serve contractor checkout, or a single CEO retained search with no data-function depth.
Verdict
Harnham is a specialist recruitment consultancy focused on data, analytics, and AI talent. Founded in 2006 and headquartered in London, it runs offices in the UK, US (including New York, San Francisco, and Phoenix), and Europe, with teams organized around niches such as data science, risk analytics, marketing insights, and digital analytics. Services span permanent placement, contract staffing, executive search, and - through the Harnham Group and Rockborne - training and embedded data teams. Public salary guides for data, analytics, and AI roles are a useful free signal for mid-market TA and hiring managers. Fees are quote-led contingent or retained placement economics rather than SaaS seats. For buyers hiring into the data and AI talent market who want a specialist desk instead of a generalist agency, Harnham is a recommend.
Score Breakdown
How Harnham scores in the categories that matter to its buyers.
Pricing
Harnham does not publish a standard buyer fee card. Placement and contract terms are quoted per role and market. As of September 2026.
Model: quote-led recruitment fees on permanent placements, plus contract and executive-search engagements. Contingent and retained structures both appear in the specialist recruiting market; expect a percentage of first-year salary or a day-rate markup that you learn on the briefing call. Salary guides are free market intelligence, not a price list for Harnham's own fees.
