Your website has the first conversation.
I design and build websites for businesses.
People who look for you 
read your website first. It should 
explain what you do and 
build trust before you ever talk.
I'm Caspar and I run Callista Studio as a sole proprietorship in Hohen Neuendorf near Berlin. I do web design and development for businesses, plus print material and AI tools that take repetitive work off your hands. We meet in person in Oberhavel and Berlin or by video.
You talk to me, start to finish.
Three areas. Websites first, everything else around them.
- Websites
A site that explains before you have to.
Landing page, company website or online shop. Designed, built, then maintained. You edit texts and images yourself, no coding needed.
