Paris-based Bitstack, a Bitcoin savings application, has
raised a $15 million Series A round led by 13books Capital, with participation
from existing investors AG2R LA MONDIALE, Plug and Play Ventures, Serena,
Stillmark, and Y Combinator.
According to the European Central Bank (ECB), prices in the
euro area increased by 23.4 per cent between October 2020 and 2025, indicating
a significant decline in the currency’s purchasing power. Against this
backdrop, Bitcoin, whose supply is capped at 21 million units, has emerged as
an alternative asset with growing adoption.
Founded in France in 2021 by Alexandre Roubaud and his
team, Bitstack’s mission is to democratise Bitcoin savings and help Europeans
preserve their purchasing power amid rising inflation. Launched in 2022, the
platform aims to make simple, regulated Bitcoin-based savings products
accessible to a broad audience.
Bitstack is best known for its savings feature that rounds
up everyday purchases to the nearest euro and automatically invests the
difference in Bitcoin. The company is now broadening its range of services for
users in France with a euro account featuring a French IBAN, enabling users to
send and receive transfers and convert part or all of their salary into
Bitcoin.
It is also launching a VISA debit card designed to reward long-term
saving through real-time, fee-free round-ups on card purchases and a “Stackback”
programme that lets users earn up to 1 per cent in Bitcoin on all euro
spending, at any merchant, with no upper limit.
Bitstack now operates in around a dozen European countries,
including Germany, Spain, the Netherlands and Italy, and offers content in the
local language of each market where the app is available. This expansion is
supported by the MiCA (Markets in Crypto-Assets) licence granted by the AMF on
30 June 2025.
With the new funding and its MiCA licence in place,
Bitstack plans to accelerate its European expansion, broaden its offering with
a euro account and new card products, and aims to reach 1 million users within
18 months as it strengthens its position in the European Bitcoin savings
market.
