My name is Don Seidenberg. I’m a native English copywriter / UX writer living in Amsterdam. My passion is making complex products and applications easy to understand and use. Achieving simplicity is at the heart of what I do.
For 20 years, I have specialized in writing digital content for both B2C and B2B clients. My experience covers many industries and niche markets in finance, data science and software. My writing can inform, persuade and improve how people interact with digital products.
what clients say
“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 Network (ING Innovation Studio)
“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 and getting everything in clear US English.
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
“Don has 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. He doesn’t need many words to describe our complex digital products. He knows how to simplify things.” – Hester Westerhof, Global Product Manager
“I worked with Don on regulatory information pieces. We needed to transform a rather legal text into a user-friendly text without losing the meaning. From my experience working closely with Don, I can say he is really good at his job and it is a pleasure to work with him. He also creates a friendly and enjoyable atmosphere for work.” – Atanas Yordanov, Technology Lawyer
“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
