As an early investor at Bitstack's seed round, FoundersX is proud to share that Bitstack has closed its $15M Series A.
Bitstack CEO Alexandre Roubaud annouced the round on LinkedIn, led by 13books Capital, joined by Y Combinator and others. This is a major milestone on its journey to reshape how Europeans save.
More from Alexandre's LinkedIn post:
Three years ago, we set out with a simple belief:
Everyone should have an easy, secure, and meaningful way to protect their purchasing power over the long term.
Since then, the momentum has been remarkable:
🔹 #1 French crypto app
🔹 300,000+ users
🔹 €300 million+ saved in bitcoin
🔹 Among the first companies in Europe to obtain a MiCA license, granted by the AMF in France
🔹 Now launching in 10+ European countries
This Series A marks the beginning of our next chapter.
Introducing the Bitstack Card
Today, we’re excited to unveil our most ambitious product expansion yet. It is a major step toward making Bitcoin savings effortless and accessible to everyone:
💳 Europe’s first VISA debit card with up to 1% Bitcoin stackback on every payment, unlimited
⚡ Instant, fee-free round-ups that automatically invest your spare change into Bitcoin
🏦 Access to a cash account with an FR IBAN, issued by one of France’s largest banks
We’re pioneering Bitcoin rewards in Europe because we believe people don’t want points or gimmicky loyalty programs.
They want Bitcoin: something real, scarce, and built for the long term.
Our beta program for the Bitstack Card opens on January 13, 2026, exclusively for the first 5,000 people on the waitlist.
Looking ahead
Our ambition remains clear:
Build the easiest, safest, and most trusted way for anyone in Europe to save in Bitcoin, consistently and without friction.
A huge thank you to our users, our team, and our investors for believing in this mission and helping us get here.
The next chapter begins. ✨
