STAMP is a Madrid-based fintech that lets international shoppers get VAT (tax-free) savings applied instantly at checkout instead of through traditional post-purchase refund processes, while also helping European retailers accept alternative payment methods (e.g. WeChat Pay, Alipay) for global tourists. Founded in 2023, it is a certified B Corp operating across Spain, Italy and Portugal with a tech hub in Valencia. It raised a €4M round in January 2026 led by VC fund Dozen.
