Käftsmäll online AB is Sebastian Kentander — coding HTML since his first 28.8kbps modem screeched its way onto good old Geocities. Since then: online ventures of every kind — from CEO of one of Sweden's biggest online personal training sites back in the day, to building websites, optimizing Google Ads, nerding out on statistics and creating web apps. An unstoppable curiosity for new ways of making things has led all the way into the AI era.

All that knowledge — from digital marketing to advertising — now lands with small business owners who'd rather focus on what they do best, without paying through the nose for simple things like marketing and websites. You do your thing. I make sure it gets seen.

Education? Every day — mostly because it's fun. New tools, new methods, new AI models; curiosity never takes a vacation. And just as much has been taught by reality: all the projects over the years, and all the firms hired along the way — both the ones that impressed and the ones that showed exactly how not to do it.

The name? “Käftsmäll” is Swedish for a punch in the jaw — and that's exactly what your digital presence should be: impossible to ignore. That's the bar for every project — from a single ad campaign to a complete AI agent.
