The projects

Presented projects have been qualified to the finals of the challenge, but you can also see more of the solutions to the Santander Bank hackathon here.


This project is a web application that seeks news about a given company, creates an abstract of found stories and aggregates that data for easier access. In addition the whole system accounts for the register and tone of the stories, in effect creating a comprehensive summary about a given company. This project was awarded 1st place in the bankITup challenge.


The team behind this project approached the competition from a slightly different angle than the rest of the participants. Aside from analysing the most easily accessible data about companies, there’s also the not-so-obvious side, something one cannot easily translate into numbers. That is the Human Resources departments and other employees. In short, their solution is meant to assess the staff’s performance, attractiveness of employment benefits, and company trust. This project was awarded 2nd place in the bankITup challenge.


FinMedi is a system detecting early signs of a company needing new financial services. Leading a well organized business is just one part of the story, expanding it is another, even more important one. To source data necessary for such estimation the FinMedi system analyses outlets like KRS, GPW, NewConnect, Twitter or and processes them using the NLP and Fuzzy Logic techniques. This project was awarded 3rd place in the bankITup challenge.


After Public Vote this project is the community choice. The team behind this solution is using SMART (Simple Multi-Attribute Rating Technique) Analysis to help investors decide on the best possible investment at any given moment. To decide on a most suitable choice the system analyzes a business’ popularity on social media that utilize Twitter API.


This project received an honorable mention in the bankITup challenge, and its name is an analogy to how solar systems work. Instead of planet, restaurants create areas or attraction for customers. How strongly a given venue attracts people depends on the Google Places rating. Comparing those “gravitational forces” between different restaurants can help calculate the investment risk, which, along with visualised areas of attraction, allows investors choose a perfect venue for their new business.

The topics covered were, for example, impact of data science on the modern world, ethics of data management, and best ways of promoting oneself. Not only was the Big Data hackathon an opportunity to challenge oneself trying to win the prize, but also to gain new knowledge and skills at the same time.
