About Valeria
Valeria is building the future of HR and payroll in Spain. We're an AI-native platform that automates contracts, payroll, and compliance for companies with high employee turnover (hospitality, delivery, events, agriculture). We're rethinking how an entire industry works—moving from manual, error-prone processes to intelligent automation.
We're a fast-growing startup backed by top investors, disrupting a €5B+ industry that's still stuck in spreadsheets and legacy software.
Valeria is an AI-native HR and payroll platform built for the way modern companies actually work. We automate the complex, compliance-heavy work that slows People teams down — so they can focus on what matters: their people.
