Paris-based Bitstack expands its Bitcoin savings suite with fresh €12.9 million funding round. Bitstack, France's leading Bitcoin savings application, announces today a €12.9 million ($15 million) Series A funding round in order to accelerate its European expansion and enhance its product offering, including the rollout of a euro account with a French IBAN and a VISA debit card featuring round-ups and Bitcoin "stackback" rewards. The round was led by 13books Capital, with participation from existing investors AG2R LA MONDIALE, Plug and Play Ventures, Serena, Stillmark, and Y Combinator. Alexandre Roubaud, co-founder and CEO at Bitstack, explains: "In three years, Bitstack has achieved exceptional growth: more than 300,000 active users have saved over €300 million in Bitcoin, and our revenue has increased tenfold in two years. These results demonstrate the growing interest of the French population in Bitcoin, in a context of economic uncertainty and monetary tensions. We are now the most widely used French crypto app." This Series A round raised by Bitstack joins a growing wave of 2025 European funding for crypto-saving and digital-asset startups. For example, BitDCA from Prague secured €7.6 million earlier this year to scale its "Littlebit" app, which automates everyday purchases into small Bitcoin investments. Meanwhile, in the institutional infrastructure segment, Tangany - a Munich-based crypto-custody provider - raised €10 million to grow its regulated digital-asset custody platform. And even larger, Treasury, a new Amsterdam-based Bitcoin "vault" startup, secured €126 million with the aim of becoming Europe's leading holder and manager of Bitcoin reserves. Viewed together, these rounds - totalling roughly €143 million - illustrate that 2025 continues to see substantial capital flow into both retail-oriented Bitcoin savings apps (like Bitstack and BitDCA) and institutional-grade custody or asset-management infrastructure (like Tangany and Treasury). Bitstack's raise represents a significant share of that activity, signalling that investors remain confident about demand for consumer-facing tools that make Bitcoin savings accessible across Europe - even as regulatory frameworks (such as MiCA) evolve. Founded in 2021 by Alexandre Roubaud and Kabir Sethi, Bitstack offers a mobile application that enables users to save in Bitcoin simply, smoothly, and effortlessly over the long term. Bitstack is best known for enabling users to automatically round up purchases to the nearest euro (e.g., a €2.60 coffee rounded to €3.00, with the €0.40 difference saved in Bitcoin). Bitstack now operates in a dozen European countries, such as Germany, Spain, the Netherlands, and Italy, offering content in the languages of each market where the app is available. This expansion is supported by the MiCA (Markets in Crypto - Assets) licence obtained on June 30 2025 from the AMF. Bitstack is the third French company to secure this approval. Michael McFadgen, co-founder and Partner at 13books Capital, adds: "With this fundraising round, Bitstack enters a new dimension. By expanding its geographic footprint and enhancing its product suite, including a VISA debit card with stackback and a euro account with a French IBAN, Bitstack is now ideally positioned to cement its status as Europe's leader in Bitcoin savings." Prices in the euro area have risen 23.4% between October 2020 and 2025, according to the European Central Bank (ECB), reflecting a marked erosion of the currency's purchasing power. Bitcoin, capped at 21 million units, offers an alternative that continues to grow in adoption. Today, nearly 4 million French people hold Bitcoin. Bitstack aims to place itself as a key player in meeting this rising demand by making Bitcoin savings accessible to the public, with a mission to help people preserve their purchasing power and achieve their life goals. Bitstack will be expanding its offering with innovative services for French users: * A euro account with a French IBAN, enabling users to send and receive transfers easily, for example, to convert part or all of their salary into Bitcoin. * A VISA debit card that rewards long - term savings discipline through two mechanisms: * Real-time, fee-free round-ups on all purchases made with the card. * "Stackback": users can earn up to 1% in Bitcoin on all euro spending, at any merchant, with no cap - a first in Europe. * A beta phase for the card begins on 13 January 2026 and will be accessible to the first 5,000 individuals on the waitlist.

Bitstack raises 15 million euros and launches its first blue card. The Bitcoin investment app Bitstack, used by over 300,000 French people, raises 15 million euros to accelerate its European expansion and unveils a card in partnership with Visa integrating the "stackback". Among the approximately 4 million Bitcoin holders in France, over 300,000 obtained them through the Bitstack app. Founded in 2021 by two alumni of McGill University (Montreal), this tricolor startup has just raised 15 million euros. The funding round was led by 13books Capital and included other players already present in previous fundraisings such as AG2R LA MONDIALE, Plug and Play Ventures, Serena, Stillmark, and Y Combinator. This is the fourth in the history of this startup, one year after raising 5 million euros. Bitstack, new partner of Visa. Known for its "automatic rounding", allowing each app user to round up to the nearest euro for every purchase made, saving the difference in bitcoin, Bitstack will introduce a new product for its users. Starting in January 2026, a debit card, created in partnership with Visa, will be available. It will be reserved for the first 5,000 customers on the waiting list in beta-test version and will introduce a new technology: the "stackback". This advancement allows any card user to receive 1% of their purchase amount credited to their bank account. "A first in Europe", according to its founders. This fundraising comes in a particular context. In addition to an ongoing political-budgetary crisis, recent months in the French crypto space have been marked by a series of kidnapping cases, such as that of Ledger's CEO, David Balland, and his partner. Nevertheless, the two partners want to affirm their confidence in the French ecosystem: "We want to show that French groups can still become European leaders", says Alexandre Roubaud, co-founder of Bitstack. "My partner and I are pure products of French Tech. We returned from Canada with this ambition to create jobs in France. Our first offices were at Station F, and Kabir (Seti, co-founder of Bitstack) came here thanks to a French Tech visa." Bitstack wants to expand into Europe. This fundraising should allow the company to expand across Europe since the Bitstack app will now be available in about ten countries of the Old Continent, including Germany, the Netherlands, and Italy. An expansion made possible by obtaining the MiCA (Markets in Crypto-Assets) approval from the AMF on June 30th. It is in this sense that it seeks to develop its teams since around twenty new employees are expected in the coming months. While these should all be recruited in France, it may be that Bitstack looks to internationalize in the coming years. "Depending on the opportunities we identify, we could have a presence in other markets", confides Alexandre Roubaud. An expansion that could be effective in the coming months and in some European countries.
