Uvik Software vs Mercor: overview
Uvik Software
Uvik Software has supplied Python engineers since 2015 and gives Tallinn, Estonia as its headquarters, with sales run from Ipswich in the UK. Its profile on Clutch says all engineers are full-time employees rather than freelancers, average seven to fourteen years of experience and pass a three-stage technical and behavioral assessment. Common work includes data platforms on Databricks or Snowflake, LLM integration and production support. Uvik says it presents profiles within 24 to 48 hours and scales squads of three to eight on 14-day terms. An aggregator reports a 30-day free replacement, which we could not confirm on Uvik's own pages.
Mercor
Mercor was founded in San Francisco in 2023 and uses AI interviews to screen applicants. It raised money at a $10 billion valuation in October 2025, mainly on the strength of supplying experts to AI labs for model training and evaluation. Product teams can hire engineers through it, but the platform is built for volume, and Sacra estimates its fee at about 30% of contractor pay. If you want two senior ML engineers for a year-long roadmap, look elsewhere. A firm that employs and manages its people fits that job better.
