The Spanish fintech has closed a funding round to modernise the global Tax Free industry and advance the development of new technology products, including artificial intelligence–based services.
Madrid-based STAMP has raised €4 million in a funding round led by Dozen, with participation from EBISU Digital, Barça Innovation Hub, and several international business angels, including Andreas Mihalovits and Thibaut Courtois through his investment arm NXTplay.
In addition to private capital, the company has secured public grants from the Spanish Ministry of Industry and Tourism, the City of Valencia, the Community of Madrid, and the City of Madrid, reflecting alignment with public initiatives focused on digitalisation, tourism, and the modernisation of commerce.
STAMP addresses long-standing inefficiencies in traditional VAT refund systems, which are typically based on post-purchase reimbursements, intermediaries, and complex processes. Its technology applies tax benefits directly at the point of sale, digitally integrating them into the payment experience in compliance with European regulations.
The model adapts to each country’s fiscal framework. In markets such as Italy, where regulation allows, purchases can be made VAT-exempt at checkout. In others, including Spain, VAT is included on the invoice, but customers receive an immediate discount equivalent to the VAT amount at the moment of payment. STAMP then validates transactions, ensures traceability, and manages tax recovery, including fraud scenarios, enabling merchants to reimburse tax authorities without assuming fiscal risk.
By reducing payment friction and simplifying access to Tax Free benefits, the platform allows merchants to use Tax Free as an effective commercial tool, supporting higher conversion rates, larger basket sizes, and improved shopping experiences for international customers. Through its integrated Tax Free and payments platform, STAMP connects European retailers with global travellers and acts as a strategic marketing and payments partner for WeChat and Alipay.
“Tax Free, as applied until now, has operated more as an administrative procedure than as an automatic consumer right. When that friction is removed, customer behaviour changes, and merchants regain control over both the shopping experience and their margins,” said Abel Navajas, CEO of STAMP.
STAMP delivers, for the first time, a real Tax Free model that does not require regulatory change, provides maximum security and prevents fraud.
According to Navajas, the funding round strengthens the company’s ability to execute its roadmap and advance its mission of enabling merchants in Southern Europe to better serve international customers by streamlining payments and turning Tax Free into a tangible purchase incentive.
The funds will be primarily used to support expansion in Spain, Italy, and Portugal, and to further develop the company’s product portfolio, with a focus on advanced international payment solutions and the launch of a new AI-based product.
