About us

We build the apps, and we answer your tickets.

Both have been true since 2016, on Server, Data Center, and Cloud. Atlassian has changed the platform more than once in that time. We still ship.

How we work

How a small team earns big trust

Made by builders, not managers.

The founders have 20 years in software. They wrote code, ran products, and designed them. They built for some of the biggest firms. We know how to build software. We do not have AI write it.

Small team, direct answers.

Your tickets go to the people who write the code. That is how we earn the trust of firms like Oracle, The Coca-Cola Company, and Kaufland. And of others like Harvard University, Continental, Electronic Arts, and NCR Corporation.

The team

Przemysław Chudziński

Co-founder · Products

He leads the product side. He shapes what the apps do, and why. He has worked in software as a product manager for more than 10 years. He turns real problems into tools that teams keep using.

Karol Jędryka

Co-founder · Architecture

He is the architect of the apps. He designs the systems they run on. He keeps the apps reliable and easy to maintain as they grow on the Atlassian Marketplace.

Agnieszka Chmiel

Design

She is our product designer. Her work makes the apps easy to use and good to look at. She brings strategic thinking to each one. She is curious and value-driven. She sees things from the user's side. She has spent more than 8 years in product teams. That helps her keep the tools clear and simple.

Kacper Maciejewski

Development

He builds the front end of the apps. He turns designs into the screens you use each day. He has an eye for detail and for ease of use.

Independent EU vendor

Who are you buying from?

We are an independent EU company. We are registered in Poland. We build for Jira and Confluence only. So we own each app from end to end.

Our founders bring 20 years of work in software, product, and design. They have worked in the UK, the Netherlands, Germany, and Poland. They were architects and product managers. Two habits have not changed. We would rather show a prototype than a slide deck. We stay consistent and skip the hype. Large firms renew with us, year after year.
