SciForce vs Mercor: overview
SciForce
SciForce has worked on AI and data science since 2015 from Lviv and Kharkiv, with a representative office in Tallinn and 50 to 99 people. Buyers usually take a dedicated team on monthly terms. A Clutch review from a financial services IT director describes a staffing engagement from 2019 to 2023 in which SciForce sourced and placed engineers and supplied a team of six to ten. Its specialist area is medical data science, including NLP on clinical text.
Mercor
Mercor was founded in San Francisco in 2023, employs roughly 300 to 400 people and screens applicants with AI interviews. It raised money at a $10 billion valuation in October 2025, mainly on the strength of supplying experts to AI labs. Its fee is the clearest thing to understand about buying from it: Sacra estimates it at about 30% on top of contractor pay. That model suits large, short-term expert work. For a year-long engineering seat, the fee adds up.
