About BitStack
BitStack is a French bitcoin savings app that rounds everyday card spending up to the next euro and buys bitcoin with the difference, alongside weekly or monthly recurring purchases; buying, selling and transfers happen in-app from EUR 1. It holds a MiCA crypto-asset service licence from the French regulator, custody of keys sits with the platform, and fiat accounts run on SEPA. Recurring buys run on a fixed amount or schedule, priced at the market quote on execution. Purchased bitcoin sits in a custody account separate from the fiat balance, and withdrawals deduct on-chain fees. The custody account reconciles monthly, and buy-sell spreads are shown in-app.
The product extends into payments: BitStack Card is a Visa card tied to a euro account that pays bitcoin back on spending, with a French IBAN and use across 20-plus European countries. Users treat it as a savings tool rather than a trading terminal, so the interface keeps to recurring buys, goals and balances. Cashback tiers and fee-free allowances scale with last month's recurring purchases and drop to 0.1% below them, and rewards settle in bitcoin, with sales and withdrawals at in-app quotes. Balances can be withdrawn at any time, funded by SEPA transfer and paid out to a same-name bank account.
On March 25, 2026, BitStack opened its equity to the public on Crowdcube, raising $4.5 million in under 24 hours from more than 8,000 individual investors — the largest such round in the EU — priced on the same terms as its $15 million Series A of December 2025 led by 13books Capital. The company obtained its MiCA licence from France's AMF on June 30, 2025, and on July 1, 2026 launched a euro account with a French IBAN plus a Visa debit card paying up to 1% back in bitcoin, entering Italy and Spain. It now has over 300,000 users and more than EUR 300 million saved in bitcoin.
BitStack will close the loop between the euro account, payment card and recurring purchases, expand across the EU on its MiCA licence, and hire about 20 people in compliance and product.
