Spanish fintech STAMP has raised €4 million in funding to globally modernize the Tax Free industry and strengthen the development of new technology products, including artificial intelligence–based services.
STAMP will advance its mission thanks to a round led by Dozen, with participation from EBISU Digital, the FC Barcelona investment vehicle Barça Innovation Hub, and several internationally renowned business angels, including Andreas Mihalovits and Thibaut Courtois through his investment arm NXTplay.
With this transaction, STAMP reinforces its position as one of the most relevant emerging technology platforms in the fields of global commerce, international payments, and Tax Free activation in Europe.
Growth in key markets and commitment to product and AI
The funds raised will be primarily used to accelerate STAMP’s expansion in its current markets — Spain, Italy, and Portugal — as well as to drive product development, with a strong focus on more advanced international payment solutions and the launch of a new artificial intelligence–based product.
The company operates in a context of transformation in shopping tourism and European retail, marked by the growth of international customers and the need to eliminate friction at the most critical moment of the sale: payment.
“This round allows us to execute our roadmap with greater determination and solidity. Our goal is clear: to fulfill our mission by empowering retailers in Southern Europe to serve global customers, removing friction from the payment process and activating Tax Free as a real purchasing incentive for consumers.
To achieve this, we have opted for a different type of investor than traditional VC: partners who, in addition to providing capital, actively engage in our mission and help accelerate market adoption of the solution. These include EBISU, an investment boutique focused on fintechs such as MyInvestor, Flanks and Flinket, and Dozen, the participatory investment platform of the Orbyn Group, with a track record of investments in companies such as Glovo and scaleups like Cuideo,” explains Abel Navajas, CEO of STAMP.
He also adds: “We have identified a major business opportunity in the football merchandising vertical. Spain and Italy are home to some of the world’s most important clubs, mobilizing millions of fans. When these fans visit us, they want to take home a souvenir of their team with the VAT discount and pay using their usual payment method. Neither Barça nor Courtois needs an introduction: both perfectly represent today’s global football economy.”
A model that redefines Tax Free as a sales lever
Unlike the traditional VAT refund (Tax Refund) system — based on complex post-purchase reimbursement processes, intermediaries, and opaque commissions — STAMP has developed a technological model that activates the fiscal benefit directly at the point of sale, integrating it digitally into the payment experience and in compliance with European regulations.
STAMP’s model adapts to the tax framework of each country in which it operates. In markets where regulation allows it, such as Italy, purchases can be made directly VAT-free at the point of sale. In other countries, such as Spain, the invoice is always issued including VAT, but the customer receives an immediate discount equivalent to the tax amount at the moment of payment, activating their Tax Free right.
The platform then validates the transaction, ensures full traceability, and manages the recovery of the amount — even in fraud scenarios — so that the retailer can be reimbursed by the relevant tax authority without assuming fiscal risk.
This approach enables retailers to use Tax Free as an effective commercial tool, increasing conversion rates, average ticket size, and international customer satisfaction, particularly in a context of growing Asian tourism and consumers accustomed to native digital payment methods.
“For more than 40 years, so-called Tax Free has failed to deliver on its promise, as in practice it has operated as a Tax Refund. Global consumers have often felt confused or even misled when seeing a service advertised in-store that did not materialize as expected: it is like claiming to accept credit cards but ultimately allowing only cash payments. Tax Free, as applied until now, has functioned more as an administrative procedure than as an automatic consumer right.
When that friction is removed, customer behavior changes and retailers regain control over both the shopping experience and their margins. STAMP offers, for the first time, a true Tax Free solution that does not require regulatory change, provides maximum security to the process, and prevents fraud,” concludes Navajas.
Institutional backing and public funding
In addition to private capital, STAMP has already secured public grants from the Ministry of Industry and Tourism, the City of Valencia, the Community of Madrid, and the City of Madrid. This institutional support strengthens the project’s viability and its alignment with policies on digitalization, tourism, and retail modernization.
Spain as a hub for innovation in global commerce
The entry of investors specialized in technology, consumer, and sports sectors, such as Barça Innovation Hub, underscores STAMP’s potential to scale its model beyond luxury tourism and extend it across the European retail ecosystem.
At a time when local retailers increasingly compete to attract global customers, STAMP aims to become a key infrastructure enabling European retailers to sell without friction, with payment methods adapted to international consumers and intelligent activation of fiscal incentives.
