what clients say
“Don provided us with UX copy support during the crucial point of the program when we worked on big market rollouts. He played a pivotal role in delivering communication to our consumers that marries the brand message with consumer objectives.” – Miika Kossi, Experience Director | adidas
“We needed a copywriter who is very flexible and can deliver high-quality content very quickly. This is especially important for an early stage and fast-changing technology company like ours.
Don’s strength really lies in his ability to communicate complex content very clearly and to the point. He truly understands the fundamentals of our software niche business. With this knowledge, Don can easily bring clarity to relatively difficult technical concepts. Crucial for an innovative technology company bringing a new concept to the market.” – Bram van Esch, CEO | Fundrbird
“Arguably one of the most difficult things in creating new businesses is finding the right words to express – often – abstract ideas in clear and clean language. Don has been extremely helpful in guiding us in the right direction through his writing and editing. He asks the right questions and is able to find the right tone & voice.” – Bob van Luijt, Founder | SeMI Technologies
“Don doesn’t need many words to describe our complex digital products. He knows how to simplify things. He worked with me on several projects at CarNext.com. He wrote a content flow to simplify how people buy a car on our platform in a very short period of time. He also wrote product pages and a video script to engage our customers.” – Hester Westerhof, Global Product Manager | CarNext.com
“Don worked with us at AG5 on two big projects. First, he worked with us on the international version of our new e-commerce website. Don is very good at improving the flow of the customer journey.
Second, he worked on the backend and helped us improve the way we structured information in our online software tool. Don’s critical eye and sharp questions made for pleasant teamwork and improved the product overall.” – Jochem Manders, Project Manager | AG5
“Don is a wonderful person to work with. On time and on point. We worked together in a design team, where he took care of the copywriting. I would highly recommend him if you need a top-class copywriter.” – Tine Matjašič, Senior Digital Product Designer | Inova IT
“I asked Don to help us write a brochure for the international corporate banking market. I was very pleased with the way he proceeded. He asked the right questions to come to the heart of the message and knew how to put himself in the position of the target market.
When we started rebuilding our website I asked Don again because he can write to the point and clear. He also has knowledge of how a website will be read best. Apart from his knowledge and expertise I find Don a very pleasant person to work with, he is honest, correct, precise and he really adds value. Thanks to Don I was able to finalize the project in time and with a good result.” – Susanne IJsenbrandt, Communication Manager | ING
