Customer testimonials

Logo, print, web design and development – we have been delighted with Karsten’s input and enthusiasm from the start. He has built two new websites for us that have proved a vital part of our business strategy and growth. Karsten is much more than just a designer, he provides insight into metrics, measures effort and sets goals.

It’s been a lot of fun working with Karsten. We’ve created something that has taken the business forward.

The branding is professional and the website is well-designed and highly visible on Google – it’s become an essential part of the success of the business.

The communication during the entire process was superb and it was obvious that he was interested in developing a long-term relationship with us.

There is no question that Karsten is a talented designer but most importantly he is a great communicator – especially his ability to share the design process in his videos. Straying from the designer’s view into the virgin users experience of the product is insightful and particularly valuable.

Top guy – ideas and style. One face to face meeting was enough with Karsten, the rest of the project was managed online. A genuine creative and good listener. The outcome is just gorgeous – Thank you.

If you’re starting a new business or upgrading an existing website, I strongly recommend Karsten. Friendly, knowledgeable, and dedicated to producing quality. Always available to answer questions, make improvements, and provide guidance. Even after the site was completed, he continues to offer unsolicited assistance.”

Karsten has been key to the success of the website and an absolute pleasure to work with. As a startup business my knowledge and understanding of branding and websites was limited. He invested so much care and interest, I almost think of him as a business partner rather than a web designer.

Karsten is responsible for Nutshell’s entire brand identity, web and mobile product design, as well as our advertising campaigns. Karsten is responsible for his own scheduling and project management, and has shown immense ability to organise and direct his own efforts. He also has worked with a team of a dozen engineers, guiding them as they build the software products that he designs. He has shown impressive growth at every review!

Karsten’s feedback from our clients are testament to the quality of the work he produces. No designer has received greater praise! He is not only a highly skilled designer & front-end developer, he also has excellent people and leadership skills. A pleasure to work with. His technical skills combined with his approach make him an invaluable member of the team.

As a web accessibility auditor I’ve worked with a few web designers in my time, but never before have I met someone with so much flair and passion. Karsten has incredible openness to making any of his websites maintain their aesthetic design yet at the same time meet accessibility requirements. Usually, I get moans and groans about the restrictions, but Karsten sees it all as a challenge and finds a way to keep everyone happy. He’ll take anything on board providing he can see a justification for it.
I’ve seen other designers work themselves into total exhaustion trying to meet deadlines, but not Karsten. He puts in 110% effort during working hours and then maintains a healthy balance between work and home. Yes, just like anyone else deadlines make him totally focussed, but as soon as they are met he’s not averse to joining in the office banter!
Every now and again he comes out of his design box and evangelises design techniques to others who are thinking about updating their jaded sites. He is a natural presenter and can make any audience realise how important the look and feel of a website is. We often have clients asking specifically if they can have Karsten assigned to them following one of these presentations so why he still maintains a modicum of modesty is beyond me!

I owe a huge thank you to Karsten for both my branding and website. Professional and easy to communicate with. He listened to my ideas and turned them in to something that suited my business needs perfectly. I’ve had many compliments on the design and would not hesitate to recommend him.

After the first meeting with Karsten, I felt mentally buoyed; even then I recognised a rare talent – someone who was incredibly talented and creative himself, but also interested in the values and talents of others. His passion for his craft led to customers insisting on working with him particularly, and the results always made both parties happy.

Karsten is passionate about design and has the ability to express this in his work where he constantly strives to push boundaries with new technology, principles and best practices. I have worked with Karsten on both commercial and personal projects and he never fails to deliver the “WOW” factor. I’d thoroughly recommend Karsten, any day of the week.

Nutshell’s team is greater than the sum of its parts, but there’s at least one member that especially stands out amongst the crowd: Karsten.
Now, it’s not just the British charm, er, “accent”, or his impressive Photoshop, but his authenticity and hardwork. Coming from a client-work background, Karsten is a man of deadlines and diligence. We equally rely on his eye for design, eagerness to iterate, and polite candor to help define product and marketing.
Karsten is unique, and it’s hard to imagine the team without him.

As lead designer, Karsten worked very closely with us to regularly discuss and share ideas for our new website. This collaboration ensured the look and feel of the site reflected our values and offered the more welcoming and user-friendly design we required.

From early concepts to final completion, Karsten’s obvious skill and passion ensured he delivered an innovative and contemporary solution that not only met the required brief but exceeded our expectations. The new site is now having a really positive impact on our customer service and engagement.

I worked with Karsten closely at Nutshell, and his attention to detail and code organization is unparalleled.

As the design lead, Karsten went out of his way to ensure that my team’s ideas about how to improve the product were heard.

A team player – going above and beyond to establish authentic relationships with those around him. Simply, Karsten is brilliant. His designs are beautiful and simplistic in nature complimenting complex products.
