Madrid-based STAMP has raised €4M in a funding round led by Dozen, with participation from EBISU Digital, Barça Innovation Hub, and a group of international business angels, including Andreas Mihalovits and footballer Thibaut Courtois through his investment vehicle NXTplay.
The company has also secured multiple public grants from the Spanish Ministry of Industry and Tourism, the City of Valencia, the Community of Madrid, and the City of Madrid, underscoring institutional support for digitalisation, tourism innovation, and the modernisation of retail infrastructure.
Fixing Friction In Traditional VAT Refunds
STAMP targets long-standing inefficiencies in Tax Free shopping, where VAT refunds are typically processed after purchase through intermediaries and complex administrative steps.
Its platform enables tax benefits to be applied instantly at the point of sale, embedding Tax Free directly into the payment flow while remaining fully compliant with European fiscal regulations.

A Country-Specific, Regulation-Ready Model
STAMP adapts its solution to national tax frameworks. In Italy, where regulations allow, purchases can be completed VAT-free at checkout. In Spain, VAT remains on the invoice, but international customers receive an immediate discount equivalent to the VAT amount.
The platform validates each transaction, ensures full traceability, and manages tax recovery, including fraud scenarios, allowing merchants to reimburse tax authorities without assuming fiscal risk.
Turning Tax Free Into A Commercial Lever
By removing payment friction and simplifying access to Tax Free benefits, STAMP enables retailers to transform Tax Free from an administrative burden into a sales driver.
Merchants using the platform can increase conversion rates, grow basket sizes, and improve the overall shopping experience for international customers. STAMP’s integrated Tax Free and payments solution connects European retailers with global travellers and acts as a strategic partner for WeChat and Alipay.
Scaling Across Southern Europe
According to CEO Abel Navajas, the funding strengthens STAMP’s ability to execute its roadmap and support merchants in Southern Europe as they serve a growing base of international shoppers.
The company plans to use the capital to expand further across Spain, Italy, and Portugal, while accelerating product development. Upcoming initiatives include enhanced international payment capabilities and a new AI-driven offering designed to optimise Tax Free operations and customer engagement.
