Bitstack Aims to Become the European Leader in Bitcoin Savings

Bitstack, helping users invest and save in bitcoin, led by Kabir Sethi & Alexandre Roubaud, has secured a $15 million Series A funding round led by 13books Capital and including existing investors AG2R LA MONDIALE, Plug and Play Ventures, Serena, Stillmark, and Y Combinator.

Eurozone prices have climbed 23.4% since 2020, eroding purchasing power, according to the ECB. With its capped supply of 21 million, Bitcoin is gaining traction; nearly 4 million people in France now hold it. Bitstack, launched in 2022, aims to make Bitcoin savings accessible and help users protect their purchasing power and reach long-term goals.

Bitstack Co-founder and President Alexandre Roubaud reports that the company has surpassed 300,000 active users, facilitated over €300 million in Bitcoin savings, and grown revenue tenfold in two years, a momentum he says reflects rising French interest in Bitcoin amid economic uncertainty. “Bitstack is now the most widely used crypto app in France,” he noted.

AG2R LA MONDIALE’s Director of Open Innovation, Yannick Lassalle, added that supporting Bitstack aligns with the group’s commitment to accessible, modern wealth-management solutions for clients seeking diversified investments.

Bitstack now operates in about ten European countries, including Germany, Spain, the Netherlands, and Italy, offering localized content for each market. This expansion follows its June 30, 2025, MiCA authorization from the AMF, making it the third French company to obtain the licence and meet Europe’s strict standards for protection, transparency, and reliability.

Best known for its Bitcoin savings feature that rounds up everyday purchases and invests the difference, Bitstack is now expanding its offering in France. Users will gain access to a Euro account with a French IBAN for seamless transfers, including the option to convert part of their salary into Bitcoin, and a VISA debit card that rewards long-term savings. The card supports free real-time roundups on all purchases and “stackback,” allowing users to earn up to 1% in Bitcoin on every euro transaction, an industry first in Europe. A beta test begins January 13, 2026, for the first 5,000 people on the waitlist.
