Paris, December 2, 2025 – Bitstack, France’s leading Bitcoin savings application, announces today a $15 million Series A funding round led by 13books Capital, with participation from existing investors AG2R LA MONDIALE, Plug and Play Ventures, Serena, Stillmark, and Y Combinator.

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[1]. Launched in 2022, Bitstack has established itself as a key player 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.

Alexandre Roubaud, Co-founder & 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.”

Yannick Lassalle, Director of Open Innovation at AG2R LA MONDIALE Group, comments: “We are delighted to support Bitstack’s development and thereby strengthen our commitment to innovative personal finance solutions that are accessible to all and tailored to the new expectations of our clients who wish to diversify their investments.”

Michael McFadgen, Co‑Founder and Partner at 13books Capital, concludes: “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.”

Bitstack Accelerates and Delivers on its European Ambition

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, meeting strict European regulatory requirements and offering enhanced protection, transparency, and reliability for its users.

The first VISA debit card in Europe offering “Stackback”:  a Bitcoin rewards programme whose benefits grow in line with the user’s savings

Known for its Bitcoin savings solution that rounds up everyday purchases to the next euro and automatically converts the difference into Bitcoin, Bitstack is 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.
