Bank accounts aggregator



As retail banks seek growth opportunities and competitive advantage, some of their core data assets are being made available to third parties. The goal is to create products and services that meet today's customer needs and expectations. We worked on a solution from ideation to a coded prototype to help a banking client understand how customers could view and interact with multiple financial products across multiple accounts, to help build retention and loyalty. 




User interviews

Conducted user interviews to define target goals. 


Conceptual design research

Defining features based on research:


- Adding accounts: You no longer have to use different applications to see your money.

Now you can have control of all your accounts in one place.


- Looking at categories: Eating out, personal care, entertainment, transportation, these are some of the categories you can find in SUMI that will help you see where you spend your money; You can also add new categories depending on your needs.


- Check your analytics: Now you can see the exact balance of your money in three different ways: categories / accounts / merchant.


Created a set wireframes and tested the conceptual direction again with users. 


Ideation workshop

- Explore how we could bring the proof of concept live.

- Created a coded-prototype.



Our account aggregator POC is named sumi, after a Japanese word for transparency. It helps people with multiple bank accounts feel better informed about their spending and improve their financial wellness by aggregating real-time data in one place and allowing them to customize the way they see and manage their spending.
