We Provide Marketing Services That Drive Real Business Growth

,,We had the pleasure of working with the agency on the new version of the website www.keno-energy.com and we can wholeheartedly recommend them as a trustworthy partner. The project was carried out in an exemplary manner at every stage – from needs analysis, through graphic design and development, to launch and post-implementation support.
We would like to particularly emphasize the professionalism, commitment, and excellent communication of the entire team, especially the project manager Kajetan, who demonstrated excellent organization, substantive support, and great attention to detail. Thanks to his work and the competence of the team, the end result met our expectations not only in terms of visuals, but above all in terms of functionality and business.
We fully recommend working with this agency to any company looking for a professional partner in the field of website design and development.,,

,,Before we started working with KartsDesign, every graphic design or UX/UI project caused a lot of frustration. We constantly had to wait for available graphic designers and discuss details with someone other than the person actually doing the project—even for the simplest tasks, such as a poster for social media.
Now, the whole process is extremely simple—I post my request on Slack or Figma, and the next day I have ready-made graphic designs. There is always one that perfectly meets my expectations. The work is done quickly, efficiently, and without any unnecessary involvement on my part. KartsDesign is a partner that is truly committed to its work – it works quickly while maintaining very high quality. Working with them is a pure pleasure.,,

,,I hereby confirm that Karts Design has provided us with a service consisting in the design and implementation of a new, expanded version of the esri.pl website. The project included dozens of subpages, numerous functionalities, content modules, and solutions supporting our key business processes.
The implementation process was smooth and orderly, and all stages – from planning, through design, to the launch of the website – were carried out with great attention to technical quality and usability. We also appreciate the open communication and willingness to respond to changes and challenges that arose during the work.
Karts Design also supported us in creating a dedicated website for the GIS Congress event, providing comprehensive services – from UX/UI concept to implementation.
We also cooperate on the ongoing development of the esri.pl website – introducing new functionalities, integrations, and creating dedicated tools to support the operation of our website.
We value Karts Design for its flexibility, timeliness, and efficient and cooperative communication. We recommend this company to organizations looking for a committed and trustworthy digital partner.,,

,,I fully and confidently recommend Karts Design, the company responsible for the implementation of the website www.word.bielsko.pl. The cooperation ran very smoothly at every stage of the project – from initial arrangements, through graphic design, to implementation and launch of the website. The team demonstrated a high level of professionalism, punctuality, and openness to the client’s needs and suggestions.
The website was created with great attention to aesthetics, functionality, and user convenience. The service is modern, clear, and intuitive to use on both desktop and mobile devices. All key features work flawlessly, and the proposed technical and visual solutions have genuinely improved communication with the audience.
Particular recognition is due for the excellent contact with the contractor, fast response to feedback, and strong commitment to refining every detail. Karts Design is a reliable and trustworthy partner for delivering web projects.,,

,,We have been working with Kajetan and the KartsDesign team for over a year. They have created two websites for us, and we commission them to prepare all graphic materials and run our social media. What we value most in our cooperation is their responsiveness. It often happens that we need something right away, and every time the response is immediate. We have not had any conflicts so far. We recommend KartsDesign to our business friends, and to my knowledge, they are also satisfied. I can therefore confidently recommend KartsDesign as a contractor who listens (which is not common today), responds, and cares about the quality of their work.,,

,,I have been working with Karts Design for a long time on projects for Green Lungs and WallEver, and from the very beginning it has been a very specific and well-organized collaboration. Communication is efficient, topics are clearly defined and implemented on time, without unnecessary complications. The team does not limit itself to simply fulfilling orders, but is genuinely involved in projects and thinks about them from a business perspective. They often propose their own solutions or improvements that really enhance the final result.
We are also currently starting a large mobile game project, which is a natural step for me after our previous collaboration and a confirmation of my trust in the Karts Design team. I can recommend them with a clear conscience as a reliable, committed, and professional partner.

,,Karts Design's implementation of our website was exemplary. We appreciate their high level of professionalism, commitment, and the fact that they selflessly went beyond the agreed scope of work to ensure that the project fully supported our mission. We are extremely grateful for this support, which will make it much easier for the Foundation to find new homes for our charges.,,
