Sovrano AI
Barcelona AI evaluation platform connecting European students and domain experts to paid remote RLHF, red-teaming, and model evaluation work.
What is Sovrano AI?
Sovrano AI is a Barcelona-based AI evaluation platform building Europe's expert human-evaluation layer for frontier AI. Launched in 2026 by the team behind CareerOS, Sovrano connects AI labs and model builders with university-verified European talent for RLHF preference ranking, red-team support, expert SFT authoring, multilingual evaluation, reasoning benchmark authoring, and long-form content review. The company positions itself as an accountable alternative to generic crowdsourcing: its network is built through 100+ university partners, 120,000+ verified evaluators, and coverage across the 23 official EU languages plus UK and US English. For contributors, Sovrano offers paid, remote, flexible projects in their field, especially across finance, law, business, marketing, STEM, engineering, operations, and multilingual evaluation. For AI companies, Sovrano supplies pre-vetted evaluators that plug into the customer's existing workflow, with EU data residency, GDPR-aligned processes, and a typical two-week pilot launch.
Mission & values
Build Europe's trusted human-evaluation layer for AI by connecting verified domain experts and students with the labs training and evaluating frontier models.
Qualifications
Sovrano is best suited for students, graduate talent, and early professionals with strong domain knowledge and the ability to evaluate AI outputs carefully. Live roles include MBA AI Operations, AI Evaluation Intern - Finance, STEM & Engineering, Marketing, Law & Regulatory, and General Business. Requirements vary by project: many roles ask for a bachelor's or master's background, bilingual or multilingual ability, and subject expertise in areas like finance, accounting, EU regulatory topics, GDPR, law, data engineering, business analytics, marketing strategy, operations, or engineering. The onboarding flow starts with a free account, then a short assessment interview tailored to the candidate's expertise, followed by matching to paid projects by language, domain, and availability. Work is remote and flexible; university internship formats may run part-time during a semester, full-time during summer, or for academic credit through partner institutions.
