I'm a software developer. Have been for over 30 years.
I'm a developer — in more ways than one. I've been developing software for over 30 years, today including artificial intelligence. I develop real estate: Johann & Anna grew out of an old mill in Stainz that I converted. I develop companies, together with my teams at 1Tool, 1Hosting, and 1Marketing. And as a Hap-Ki-Do kids' trainer, I develop children, quite literally — their discipline, their confidence, their inner strength. During the day I develop software and companies. In the evening I develop self-confidence. And that's exactly why I see the same thread running through all of it.
From a moped to a company with 25 employees
At 16, I rode my moped from town to town and company to company, digitalizing businesses. Since 1995 I've sat in front of a computer nearly every day — first as a self-taught programmer, then as an entrepreneur. Today, as managing director of Körbler GmbH, I lead a team of 25 people who now guide around 3,000 customers into the digital future. Our headquarters: a stylishly converted farmhouse in Wagna, southern Styria — with a modern extension and a barbecue area for the team in the courtyard.
From contact manager to a 30-module business platform
That work is where my software 1Tool came from — originally launched in 2012 as a simple contact manager and newsletter tool called "KundenMeister," today a full business platform with around 30 modules for CRM, ERP, project management, and more. Used by small trade businesses just as much as by companies like Austrian Post, Ricola, Mondi, or Novartis.
Father, author, and kids' self-defense trainer
Alongside entrepreneurship, a second thing matters just as much to me: making kids strong. As a father of two daughters and a Hap-Ki-Do kids' trainer, I've spent years exploring how children can develop self-confidence, discipline, and real strength in an increasingly digital world — on the mat just as much as at home. That experience is the foundation of my book "The Art of Parenting Through Chaos," published in 2026 by Telemach Verlag.
Structure creates freedom
Whether in business, in parenting, or in the dojo — for me, it all connects to one principle: structure creates freedom. Anyone with clear systems and a clear stance doesn't have to renegotiate everything every day, and can focus on what actually matters.
