Quantiphi vs N-iX: overview

Quantiphi

Quantiphi, based in Marlborough, Massachusetts and founded in 2013, is the largest company on this page that works only on AI and data, with directory estimates between 3,000 and more than 4,000 people. Its Elastic Staffing program, built with AWS, places generative AI and ML specialists into client teams. That scale is the reason it ranks here: no other AI-only supplier can staff ML, MLOps, data and LLM roles in parallel. Google Cloud named it 2025 AI Partner of the Year for North America. The cost is attention, since staffing is one product inside a large consulting business.

N-iX

N-iX has been in business since 2002, has its registered headquarters in Malta and does most of its delivery from Ukraine, Poland and other Central European countries. Company materials cite more than 2,400 engineers and staff augmentation as one of three engagement models. It is hiring ML engineers in 2026, and one listing seeks a lead computer-vision engineer for an external expert network that conducts technical interviews, which suggests specialists take part in its screening for senior roles. The firm is large and stable, but ML is a fraction of its work.
