Design and technology agency offering UI/UX, web development and digital growth work for international clients


Websites and digital products meant to increase sales, generate leads and solve specific business problems are what FASTSITE builds. Each project opens with research, followed by a workshop designed around the particular product. The agency is based in Poland and publishes its site in English. It describes itself as a business partner rather than a supplier, and it says it treats each project as a business asset that should justify its cost.
The workshop is followed by an analysis phase in which the concept is set out clearly, and then by prototyping. The agency says its prototypes allow testing and adjustment before the final product is made, so that changes are made early and are cheaper than changes after launch. Development then uses the agency's full range of skills and technical experience to produce a product of high quality. The agency says it does not take on projects it does not understand, and it encourages clients to use the findings from its research.
Once a product is live, FASTSITE argues that it needs regular change. It says updates should be based on feedback from users and on the actions of competitors, so the product keeps pace with the market. This optimisation phase is the last of the four stages the agency describes, which run from analysis to prototyping, development and continuing improvement.
The agency describes its proprietary project management methodology as one of its main strengths. It says the method is designed to make sure that the business goals behind a project are met, and it argues that cooperation built on trust, transparency and a shared understanding of the client's needs is the foundation of a long relationship. The agency states that it does not start projects that lack a defined goal, and it describes efficiency as part of its culture.
The case studies on the site cover a range of sectors, including an online real estate agency and a food-focused user experience project. The agency says its clients span many industries with separate aims, and it describes its work as building products for each one's particular challenges rather than offering a standard package. The emphasis throughout is on the link between a product and the commercial results it should deliver.
FASTSITE keeps a logbook of its discoveries and publishes articles drawn from its research. Subjects include how to run a company blog effectively, why content marketing means far more than a company blog, and trends in digital marketing for 2022. The agency says it prepares for each new challenge by doing a lot of research and drawing conclusions, and it shares the most interesting findings in the logbook.
