Gdańsk · product studio
We build products we run ourselves. That's why we know how to build yours.
TestNest, FitSherpa and Misja:Zakupy are our own apps, serving real users every day. We bring that same accountability for quality and upkeep to the select projects we take on for clients.
Products we run

An app that automatically generates tests and quizzes for teachers.

Misja:Zakupy

We also build for hire
Alongside our own products, we take on select external work: mobile apps, web systems, integrations and automation. We look for a clear goal and a real outcome, not for closing every inquiry that lands in our inbox.

How we work
Diagnose
We start with the question we ask ourselves on our own products: what specific problem this solves, and for whom. Technology comes after that.
Scope
We cut a first stage that can actually ship and get tested on real users, instead of promising the whole system at once.
Ship
We implement, measure the effect, and decide the next step together, the same way we do every week on our own apps.
