Hosting the VSUD
At first glance, doing business in Germany seems familiar for a Swiss company. But it is precisely this perceived familiarity that presents challenges that are often underestimated. This makes the exchange within the Association of Swiss Companies in Germany (VSUD)—which we hosted last week—all the more valuable.
People, Planet, Progress
This summer we became a member of the wvib—the Baden Association of Industrial Companies. We had the opportunity to introduce ourselves as a new member in the association’s magazine, “Wissen & Wärme.”
Positive Leadership
Positive Leadership isn’t a one-time training session—it’s a shared journey. Through our regular Freshup workshops, we ensure that we, as a leadership team, are all pulling in the same direction. One thought from the last workshop really stuck with us: What good are the best strengths if people don’t have the confidence to show them? That’s exactly why it’s so important to us to create a culture where openness, trust, and participation are second nature.
