We'd previously worked with a number of designers but had never found the right mix of skills, high-quality design, strong communication and value that we were looking for. We approached JCD with a brief to work on our new website (...). They've worked very closely with us, responded to changes quickly. We're extremely pleased with the new website and have had some lovely comments from clients. They're a great partner and we look forward to working with them more.

I worked with Adam at our first startup, Niania.pl. Was then a great value for our company being on of the key developers. Recently we had a chance to work together again to build a website of Market One Capital with jcd.pl. We are very happy with the service.

I've worked with many developers and designers and from the bottom of my heart I can say, that working together with JCD was the most pleasant. It's all down to the great communication process and mutual understanding.

I collaborated with Adam and the JCD team on the website design project. I recall this cooperation as fluent and professional. Adam is good at his word, well organized and competent. He can explain details, so that they are understandable even for non-insiders :). And, last but not least, he is a great guy with a sense of humour :)
