SciForce vs Harnham: overview

SciForce

SciForce has worked on AI and data science since 2015, with R&D offices in Lviv and Kharkiv and a representative office in Tallinn. Directories list 50 to 99 people. The clearest evidence of its staffing work is a Clutch review from a financial services IT director describing an engagement from January 2019 to February 2023 in which SciForce sourced and placed engineering talent and supplied a team of six to ten. Medical data science is a notable specialty, alongside NLP and logistics AI.

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.
