Putting Sepa Direct Debits into any business hands 

The web economy has been through many great disruptions during the last 5 years. 

New business models have appeared and grown, reshaping the way we consume and interact with merchants and brands: streaming, crowdfunding, "on demand", "as-a-service", etc. 

However, the way we pay has not changed. Credit card is still by far the most used payment method for online transactions in Europe.

With all the limits this payment method have: expiry dates, amount limits, subject to fraud and loss.

But if you are looking for alternatives to credit cards, few options exist.

Payment methods like Sepa Direct Debit are more flexible, widespread, cost-effective and therefore perfectly suited to the new web economy. But they remain difficult to use for online purposes: popular payment services providers neglect this payment method, and banks are light years away from developping products in line with the standards of the modern web economy.

This is the reason why we created Finstack.

Our mission: empowering the new web economy

By making it easy and quick for any business to take Sepa Direct Debits, and providing your customers with a smooth payment experience. 

Because we believe payment can be a powerful leverage for your business if you choose the right payment method.

Who we are


Located in Paris France, we are a team of web entrepreneurs coming from different backgrounds: IT Services, Security and Finance.

During our previous professional experiences as consultants, developers or entrepreneurs, we have been struggling with web payment solutions everytime we needed to use other payment methods than credit cards.

In the beginning of 2015, our team came together with the idea to build a simple to use, technically well-designed yet powerful Sepa Direct Debit payment solution to help online businesses take recurring payments.
