Are you experiencing this?

I am Claus-Stefan!

I will help you digitilize your business and find your digital niche. I will draft a digital transformation plan with you and will guide you through the process until you reach your goal. You will become more familiar with a world that may be new to you and keep an overview at all times. Here you can listen to my podcast.

I have enjoyed working with people and developing new ideas together for over 22 years.  In 1997, I founded the company ISDD GmbH with a friend in Schönwald in the Black Forest. Together, we created websites for communities, companies and hotels, as well as for an online shop for a cuckoo clock manufacturer. In 2004, we fortuitously got the internet address cuckooclocks.com. We received an offer for this address of 10.000$ from a US-company. I casually told my wife about this at dinner. She said: “Stop – we are in the birthplace of the cuckoo clock – you have already programmed an online shop for a cuckoo clock manufacturer – and you have the internet address cuckooclocks.com – we are creating our own cuckoo clock online shop! So we created our own cuckoo clock online shop and have successfully digitilized this business. Our shop is now available in 10 languages and we are represented worldwide through Amazon and Ebay. Now, I am excited to share my experience and skills with you to help you start or transform your business.
