The One and Only

Tell us something about yourself. You want to work with us and create something awesome together? Nothing more simple than just let us now that you exist :)

What we do

We believe that ideas should be bigger than wallets. They can come from anywhere and every voice is important.
When our clients reach their ambitions and dreams, we reach ours.

We’ve built our business to last, based on long-term relationships with our clients, with our partners and with our people.
Money isn’t a dirty word. We believe that responsibly earned profit is a force for good.

Umbraco development

We are the most experienced company in Umbraco development in Poland. We are with Umbraco from almost the begginings of this CMS with bigger and smaller projects for various clients. We use it, we love it, we want to spread this love with others.

Mobile websites and applications

We were building responsive websites before it was cool :) We are specialized in HTML5, multiple Javascript frameworks, cross-platform development (Sencha Touch, Phonegap) and other stuff required to bring companies to this amazing, mobile world. We build for Windows Phone, iOS and Android.

Web design & build

We are always with our clients from the beggining. We analyze, choose the best option (or create our own :)) and deliver it. We also keep one's finger on the pulse of each solution after it's delivered.

Developers training

As we are always saying: we love to share our knowledge and we are good at it!
We can train other developers (e.g. in your company?) in technologies and tools such as: HTML5, JavaScript, ASP.NET, ASP.NET MVC, Umbraco CMS, Windows Phone, Responsive Web Design and other. Contact with us to get more information.

IT consulting, strategy, planning and research

We are here to help. We can help with your problems and remove from you a dark vision of cooperating with other IT companies.
Our knowledge is the key to multiple problems, not only our own. If we can learn from other mistakes, why you can't learn from ours?

Public speaking

We can share our story, problems or specialized, geeky knowledge with bigger crowd. We have experience with trainings and presentations in front of hundreds of people. We love to talk what is maybe weird according to nerd vision. If you are organising any event in which we can fit with ourselves - contact with us and share your thoughts.

We can always connect our skills with other talented people.
We can be part of your team, "white labeling" company or just an outsourcing team for your solutions or ideas. We are open to talk, always.

Let's create something awesome together!

We treat our clients as a friends. Real friendship is build on trust and challanging each other to be the best that we can be.
Friends not tell you just what you want to hear, they always tell you what you need to know. That's how we work and we are really proud of it.
