Sciforce vs Mercor: overview
Sciforce
Sciforce was founded in 2015 with R&D offices in Lviv and Kharkiv and a representative office in Tallinn. Its teams cover AI and ML, NLP, computer vision and medical data science, and the company puts weight on ethical AI development. One Clutch reviewer, a Stockholm financial services firm, describes a staff augmentation engagement that ran from 2019 to 2023, with Sciforce recruiting and placing engineers for the client.
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%.
