Econverse 2026

Our Finance Flow concept and prototype began in a 36-hour sprint. We went on to place third in the Econverse national grand final.

The first 36 hours

Econverse gives student teams problems from finance and technology partners, then 36 hours to propose a business and pitch it. Our challenge became Finance Flow, an app for learning about personal finance and investing.

We had to choose a user, a learning problem and a small enough scope for a short demonstration. Our prototype focused on practising financial choices and showing progress.

Getting to the final

Finance Flow qualified for the national final at the European Financial Congress. Before the event, we tightened the product concept and simplified the pitch. In a few minutes, we needed to explain the problem, show how the app worked and make a case for building it further.

Our team finished third and received PLN 2,000. The award recognises the competition entry; the current Finance Flow product includes substantial work completed afterwards.

Development after Econverse

I independently build Finance Flow's software, including the React Native and Expo mobile app, Next.js school dashboard and Supabase/PostgreSQL backend. Most development took place after the competition.

The engineering work now includes branching financial simulations, tests of decision paths and database transactions that prevent duplicate rewards. I am developing the product in collaboration with schools.
