Bitstack, a leading French Bitcoin savings application, has successfully closed a $15 million Series A funding round led by 13books Capital. This significant investment, which includes participation from existing backers like AG2R LA MONDIALE and Y Combinator, will fuel the company's ambitious European expansion. The funding will also support the launch of a pioneering VISA debit card designed to integrate Bitcoin savings into daily spending habits across the continent.
Addressing Economic Uncertainty
Amidst growing economic uncertainty, Bitstack's services are gaining significant traction as consumers seek alternatives to traditional currency. The European Central Bank notes a 23.4% price increase in the euro area between 2020 and 2025, eroding purchasing power. In response, over 300,000 active users have already saved more than €300 million in Bitcoin through the platform, demonstrating strong market demand for alternative savings vehicles.
Strategic European Expansion
The company is now accelerating its international growth, making its fully localized application available in approximately a dozen European nations, including Germany, Spain, and Italy. This expansion is strategically supported by the Markets in Crypto-Assets (MiCA) license, which Bitstack secured from France's AMF on June 30, 2025. This regulatory approval ensures a high standard of user protection and transparency, paving the way for broader European adoption.
Innovative Financial Products Launch
A key part of Bitstack's enhanced offering is the introduction of a euro account with a French IBAN, simplifying fund transfers for users. The firm is also launching a VISA debit card that rewards long-term savings discipline through innovative features. This includes real-time, fee-free round-ups on all purchases and a unique "stackback" rewards program, a first for the European market.
The "stackback" program allows users to earn up to 1% in Bitcoin on all their euro expenditures without any spending caps. This feature aims to seamlessly integrate Bitcoin accumulation into everyday financial habits, rewarding users for their regular spending. A beta test for the new card is scheduled to begin on January 13, 2026, for the first 5,000 individuals on the waitlist.
Future Growth and Team Development
With this new capital, Bitstack is poised for substantial growth, aiming to reach one million users within the next 18 months. To support this trajectory, the company plans to expand its team of thirty by recruiting twenty new talents in 2026. These new hires will bolster key departments such as compliance, engineering, and marketing to drive product development and European operations.
This $15 million funding round marks a pivotal moment for Bitstack, solidifying its transition from a French startup to a major European player. By combining strategic expansion, regulatory compliance, and innovative financial products, the company is well-equipped to lead the Bitcoin savings market. Bitstack is now strongly positioned to empower a wider audience to preserve their purchasing power through accessible, long-term digital asset savings.
