Bitstack is France’s leading Bitcoin savings app, built around round-ups and automated recurring purchases rather than trading. Most retail crypto products optimise for the active speculator, presenting order books, leverage, and long asset menus. Bitstack assumes the opposite user: someone who wants gradual exposure without timing the market, and who is better served by rounding up card purchases and setting a weekly buy than by watching charts. The product is a savings habit that happens to be denominated in Bitcoin.

Positioning it as saving rather than trading changes the regulatory posture, the marketing, and the retention profile, and it suits an investor base that grew up with automated investing apps. Backed since 2022 and funded through a 15 million dollar Series A in 2025, Bitstack is expanding from France across Europe. The deep-domain work is unglamorous and defensible: licensing per jurisdiction, custody, banking partnerships, and compliance in a sector where those are the actual barriers. Regulatory groundwork of that kind travels well, since each additional European market reuses most of the same infrastructure.
