Sovrano AI is a Barcelona team that grew out of CareerOS, a 2022 student job startup with a network of 200+ university partners. It connects graduates and domain experts with paid AI evaluation work such as RLHF ranking, multilingual evaluation, fact-checking and red-teaming, and it also posts expert roles that pay for building finished slide decks. Every listing shows its rate before you apply, and many current listings are paid internships.
