Algoscale vs Mercor: overview
Algoscale
Neeraj Agarwal founded Algoscale in 2014 after working at a data science consulting firm, and the company has stayed in data and AI ever since. It is headquartered in Newark, New Jersey, with its delivery center in Noida, India. The staff augmentation service supplies data engineers, data scientists, ML engineers and analytics experts, with cloud and DevOps people when a project needs them, and the company advertises a no-risk free trial when a new developer starts.
Mercor
Mercor was founded in 2023 and uses AI agents to interview and match contractors, and in October 2025 it closed a Series C at a $10 billion valuation. It began by hiring software engineers, and a spokesperson said in 2025 that engineers were still its most requested talent. More than 90% of its revenue, though, now comes from AI model companies buying expert work for training data. It still places people in full-time, part-time and contract roles with other clients, and an analysis by Sacra puts its recruiting fee at 30%.
