Marius Olech

Marius Olech explores how technology, culture and money are changing the way people spend, save, pay and live online.

OLECH is not a finance blog. Every story starts from something you already recognise: a group chat that never settles up, a phone you're renting without noticing, an app that quietly became a bank. The money part shows up as the explanation.

Each story starts as a short vertical video on X, designed to be watched in under a minute. If it grabs you, the long version lives here: sourced, written and clear about where the facts stop and the analysis begins.
