Fintech leader develops a new treasury management product for mid-sized banks


For many companies, developing a new software product can be daunting. Their teams are used to supporting and enhancing existing products which is very different from designing and developing a new product.

With an existing product, you know your customers and their needs, but when developing a new product, you only have ideas to start with. That’s why teams need additional process and technology guidance. In this case, the client found themselves in a similar position.

As a leading provider of technology solutions and payment processing services for the financial services industry, this client supports more than 11,000 financial institutions and generates over $1 billion in revenue annually.

The Problem

The client identified a market opportunity to build a treasury management product that would help them serve larger financial institutions.

The market was saturated with products that were too complex and cumbersome to use. This complexity created inefficiencies and increased operational costs for the banks and their customers. Therefore, they chose to pursue user experience as a core differentiation strategy.

The client was looking for a partner who could bring a user-centered design approach to discovering and developing modern software. That’s why they decided to partner with ProductStack.


“ProductStack knows how to do product development, ProductStack’s approach is very well thought out, is very disciplined, and very repeatable. ProductStack has high integrity, therefore I would say they could help anyone bring a product to market, especially a software product using modern technology.”

ProductStack's Role

Product Definition & Planning

The engagement started with ProductStack’s Product Definition and Planning Workshop. In this phase, ProductStack helped the client formalize their product strategy and create a product roadmap. This enabled the client to align the project stakeholders to a shared product vision and an approach that would work within their unique context.

The team also established that the product’s usability would be a key differentiator in the market. While the client had a wealth of knowledge in their backend infrastructure, they did not have the expertise in user experience or modern user interface (UI) technologies. That’s why they engaged ProductStack to design and develop the user interface while having their team members develop the backend APIs.

Product Discovery

To get started, ProductStack and the client created a joint discovery team of subject matter experts, product managers, user experience designers, and experienced technical architects.


The ProductStack team conducted user research and based on the insights gained, created high-fidelity prototypes that demonstrated key aspects of the software. Then the team conducted usability tests and iterated till the product met the users’ needs and was intuitive to use. Once verified, the prototypes were ready for development.

Product Development

During development, the ProductStack team was responsible for developing the user interface layer, whereas the client team owned the integration of the API layer to their existing backend systems.

The joint team followed Agile methodologies, using three week sprints to develop the software. The software was delivered in small chunks but over the course of the engagement, over 125 views were developed and integrated into the back-end infrastructure. Both teams followed a rigorous definition of “done,” which ensured that the product was developed with high-quality.
