Filip has a unique combo of skills: design & development. He proactively suggested new ideas on how to make the website not just functional but esthetic. He created awesome visual mocks, iterated quickly based on my input and then coded all of it into a superb website. Throughout the process he was a charm to work with. All All in all great designer-developer with an outstanding sense for client service.

I enjoyed working with Filip on these landing pages. He created very nice conversion centered designs, and were very knowledgeable about the Unbounce platform. I originally wanted to hire someone in the U.S., but I was very happy with the outcome.

I've worked with a number of large digital marketing agencies in the past, usually with lacklustre results. I can confidently say Filip delivered twice the expected results at half the price using Figma, Leadpages, and Hotjar. If you are thinking of having a sales letter / long-form landing page designed, you can't go wrong with them. You won't be disappointed."
Chloe DavisMarketing Manager
"We had a positive experience with Filip, he helped us on several landing pages as well as animated visuals. Communication was always smooth and he was very easy to work with!"
FullviewCEO
"I contracted Filip to come up with a new design for our API Marketing landing page and did a great job with it. We had some time delays on the project on our end, and he was very understanding and flexible with our delays and I really appreciated that. He was great communicator and took our feedback and incorporated it into design revisions. It was great working with Filip. Thanks!"
WhichBrowserCEO
"Filip were an absolute pleasure to work with, he understood the project requirements and delivered exactly what we were looking for, in-fact he actually exceeded what we were expecting and offered valuable recommendations as well. We will be working with Filip for a long time into the future."
IOTSolutionsCEO
"Filip was engaged to design a build out a landing page for us and they delivered on the work exceptionally. His process was streamlined and they got the job done quickly and to the timeline we set. Communication was good and he had great response times when discussing feedback or changes. Overall the page/work was awesome and will likely engage him again when needed."
TradeCoffeeMarketing Manager
"He made the whole design processes easy. He came up with a strategy, and executed it following a methodical process. He took into account our competition, our design preferences and our rather unique product. Filip delivered everything on time and exceeded my expectations. I was very impressed and would highly recommend him."

FAQ

Are you an agency?

No, “we” is actually Filip only. There’s no outsourcing here and you only get to speak with Filip.

Yes, however implementation can sometimes be tricky, especially if you’re not on Shopify, WordPress, Unbounce or Laravel. In that scenario, we prefer to deal with design and analytics and let your team take care of implementation.

For most website it’s two tests every two weeks.

We don’t use fake experiment data as advertising. Meaning we don’t run an experiment for 2 weeks and then say it earned millions in annual revenue (projecting experiments short term gains to a whole year). We don’t take on as many clients as possible (since it’s only Filip doing the work).

We can work with any budget – what you get will scale accordingly.
