Uvik Software vs Mercor: overview
Uvik Software
Uvik Software, founded in 2015 and based in Tallinn with a sales office in Ipswich, sells Python engineers for data, AI and backend work, and it is one of the few providers here whose buying terms you can read before calling. Clutch lists a $50 to $99 hourly band. Squads of three to eight engineers can be scaled up or down on 14 days' notice, and profiles arrive within 24 to 48 hours. All engineers are full-time employees with seven to fourteen years of experience on average. An aggregator mentions a 30-day free replacement, but Uvik's own pages don't confirm it.
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.
