Bitstack, a Paris-based Bitcoin savings app, closed a €12.9 million Series A to accelerate European expansion and enhance its product, including a euro account with a French IBAN and a VISA debit card with round-ups and Bitcoin rewards.

Key product updates include a euro account with a French IBAN to facilitate salary-to-Bitcoin conversions and a VISA debit card offering fee-free round-ups and up to 1% Bitcoin rewards (Stackback) with no cap; the card beta starts in mid-January 2026 for the first 5,000 on the waitlist.

The app uses automatic round-ups of everyday purchases and converts spare change to Bitcoin via dollar-cost averaging, alongside a VISA card with the Stackback rewards program.

Bitstack operates in roughly a dozen European countries, providing local language support in markets like Germany, Spain, the Netherlands, and Italy.

Bitstack obtained the MiCA licence from France’s AMF on 30 June 2025, enabling regulated operation across Europe.

The MiCA licence approved by the AMF positions Bitstack for expansive European growth and regulatory compliance.

The licence makes Bitstack one of the early European crypto savers to secure MiCA authorization, supporting its cross-border expansion.

Founders are Alexandre Roubaud (CEO) and Kabir Sethi (CTO), McGill University alumni, who launched Bitstack in April 2021 in southern France to benefit from favorable regulations.

The round underlines growing European investor appetite for consumer Bitcoin savings tools and related crypto infrastructure, alongside other 2025 European funding rounds.

13books Capital’s Michael McFadgen emphasizes Bitstack’s ambition to lead Europe in Bitcoin savings and deepen its continental footprint.

Bitstack aims to help users preserve purchasing power amid euro-area inflation, positioning itself as Europe’s leader in Bitcoin savings while expanding across more markets and services.

Upcoming milestones include expanding access to more markets, enhancing savings products, and leveraging the new regulatory licence to strengthen its European position.
