Bitstack raises €15 million and unveils its bank account with a Bitcoin Visa card
The subject had been in the works for some time: this morning, Bitstack officially announced a euro account with a French IBAN and the upcoming arrival of a Visa debit card with Bitcoin (BTC) cashback:

Firstly, the news is accompanied by another major announcement, namely a $15 million fundraising round led by 13books Capital. This round of financing includes participation from AG2R LA MONDIALE, Plug and Play Ventures, Serena, Stillmark, and Y Combinator.
For Alexandre Roubaud, co-founder and president of Bitstack, this investor confidence stems from his company’s remarkable performance:
In three years, Bitstack has experienced 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 French public’s massive interest in Bitcoin, in a context of economic uncertainty and monetary tensions. We are now the most widely used French crypto app.
Having obtained its MicA approval last June, Bitstack can now move up to the next level on a European scale, and the new features we are discussing today could help it do so.
Its payment card will introduce the concept of stackback, a first in Europe, which will allow users to recover up to 1% of their spending in euros at any merchant, all paid back in satoshis. The rounding up of purchases made with this card will be done in real time and at no cost. This new service will begin a test phase on January 13, initially for the first 5,000 people on the waiting list.
Michael McFadgen, co-founder of 13books Capital, believes that with all these new features, Bitstack now has “everything it needs to establish its position as the European leader in Bitcoin savings.”
In addition, while the startup currently has 30 employees, around 20 new recruits will join the team in 2026 to strengthen Bitstack’s technical, marketing, compliance, and customer support departments.
