We are Zusia

Zusia team — Build, Design, Counsel

A lawyer, a designer, and a software engineer walk into a bar… It was in Poland, so they all end up talking about taxes.

We moved to Poland and burned evenings on ZUS, PIT, and “ask in five Telegram chats.” If that sounds familiar — you’re why Zusia exists.

Cited answers on ZUS and tax. In your language. Built by people in the same boat.
