How Powens Helps Bitstack Make Bitcoin Accessible to Everyone
date Oct 29, 2025

Bitstack, a fast-growing French fintech, helps everyday consumers invest in the globally popular cryptocurrency Bitcoin. The founders of Bitstack believe widespread Bitcoin accessibility is necessary for both wealth creation and financial freedom. One of the company’s core objectives is to provide the easiest and most trustworthy platform for buying, selling, sending, and receiving Bitcoin. 

To power effortless Bitcoin investments, Bitstack partnered with Powens. 

Bitcoin democratization starts with Open Banking account aggregation

Bitstack is the first application in France to allow consumers to save and invest in Bitcoin automatically.

Auto-roundups, the company’s flagship product and feature, was developed to help new users start saving and investing in Bitcoin for the first time. Doing so requires the ability to access customer bank accounts across different banking providers, including LCL, Société Générale, and Crédit Agricole. Bitstack aimed to connect any bank to its application so customers could benefit regardless of which bank they use. 

“We decided to use Open Banking solutions and bank account aggregation so that the customer connects their account and can then activate automatic roundups. Bitstack, in return, gets read-only access to the user’s account. And once they make a transaction, Bitstack can calculate rounding and invest the spare change in Bitcoin.” Alexandre Roubaud, Co-Founder & CEO of Bitstack

Users can also schedule recurring investment payments via Bitstack, either daily, weekly, or monthly, in their chosen amount. These are then automatically invested in Bitcoin through the app. 

Why Bitstack chose Powens 

When choosing an Open Banking provider, Bitstack prioritized two criteria — simplicity and security.

On the simplicity side of things, the company wanted to make the customer journey as fluid and easy as possible. But Bitstack wasn’t just looking for simplicity for customers; the company also wanted a smooth integration process that allowed for quick development of the auto-roundups feature. 

“Right now, we have one main KPI, which is conversion rate across the customer journey. And so we work on a daily basis with the Powens team on the analysis of conversion rates on the journey to ensure that, overall — and also by connector and by bank — we achieve the best possible conversion rates.” 

As for security, Bitstack needed a highly secure and compliant solution. The company sought out a platform that could instill confidence that a user’s bank data would never be leaked, and they found that in Powens.

Powens didn’t just offer the simplicity and security Bitstack needed, however. They also provided comprehensive and genuine, human-based support.

“One of the benefits of working with Powens is having the team available when a connector goes down or when conversion rates are not meeting expectations, and to be able to react as quickly as possible. And on our side, to be able to keep onboarding new clients, and to provide them with a satisfactory experience, and ultimately help them save and invest in Bitcoin.”

Bitstack’s partnership with Powens enabled the company to take its product to market fast, all while delivering a seamless user experience and bank-grade security. 

“We have already helped more than 200,000 French people to save and invest over 200 million euros in Bitcoin. What appealed to people was that we made Bitcoin accessible to everyone, with a strong focus on simplicity, accessibility, and security.”

A major component driving the success of this partnership is the combination of expert Open Banking implementations within French markets and Powens’ human touch.
