Two decades of growth

Founded in 2002, Körbler GmbH has stood for sustainable growth ever since: in 2025 we crossed the €2 million annual revenue mark for the first time, more than half of it recurring. Built on clear strategy, a strong focus on quality, and long-term customer relationships.

From KundenMeister to 1Tool

1Tool started in 2012 as a simple contact manager with newsletter sending, under the name "KundenMeister." Over ten years it grew into a full business platform — in 2022 we renamed it "1Tool" because we needed a name that reflects just how many modules the software now offers: nearly 30, spanning CRM, ERP, and project management. 1Tool is used by small trade businesses just as much as by companies like Austrian Post, Ricola, Mondi, or Novartis.

1Develop — our umbrella for development

I'm a software developer, not a marketer who just sells technology. 1Develop brings together what I've stood for over 30 years: development — of real estate just as much as of software. From planning through design and development to quality control, launch, and marketing, 1Develop guides projects like Johann & Anna from first idea to market.

Other projects

Beyond 1Tool, 1Hosting, and 1Marketing, I've built other digital projects over the years: GetAWebpage, a platform for professional, affordable websites from a single source, and Steirische Wirtschaft, a platform for news and profiles of Styrian businesses. Plus Johann & Anna, five vacation apartments in western Styria.

Investments

As managing director and co-founder, I'm also involved with Bikeportal.at GmbH, and as co-founder and shareholder with Dagobert Invest AG, one of the top-rated Austrian crowdinvesting platforms for real estate projects.
