Simona the Crumb... uh, chocolate monster: No matter in which form, with chocolate you just make Simona happy - not only because you don't have to cook first, because that's not her thing. Strengthened with the extra portion of cocoa beans, she rocks new business in Business Development, but there's only one thing to switch off: cosiness.

Inga Feischen
Knowledge Lead Project Management & Business Plattforms
Inga. This name stands for adventure and cordiality. There is probably only little left on Inga's Bucket List, because what she has already experienced resembles a novel: Piranhas fishing in the Amazon, the most dangerous road in the world ("Death Road") mountain biking and house running (and that's only a fraction!). In between her adventures she is involved in the project management with heart and gets her balance at indoor cycling.

He can also enjoy the moment particularly well when camping. He combines this type of travel with outdoor activities such as hiking, climbing or cycling.

Solution Architect
You can usually find Lars with a large pot of filter coffee, deep in research, or lost in a sci-fi audiobook. After over a decade in Bonn, he finds his balance by taking walks in nature or playing soccer. When he has more time, his true escape is the open road in his camper, most often chasing the waves and sun of the Atlantic coast, with Morocco and Asia waiting on his horizon. He is equally at home in a local café, always ready to connect over a coffee, a game of table tennis, or a beer while watching football.

Lea is a true native of Cologne, a book club founder, and a passionate organizer through and through. When she isn’t bringing people or projects together, she practices yoga, dances West Coast Swing, or volunteers. Her favorite movie is *Finding Nemo*, she eats kiwis with the skin on, and on Sunday evenings, she either watches the *Tatort* team or—as a true fan—the Kölner Haie.

Administration & Financial Services Manager
At SUNZINET, Uli keeps many threads together: from administration and schedule management to organizational workflows and the processing of accounts receivable. She also oversees workplace safety and corporate health management initiatives. In these endeavors, she is supported by the office dog, Duplo—the official "Feel-Good Manager" and expert in boosting morale. After work, other projects await: her balcony and garden, nature, geocaching, billiards, and, of course, organizing daily family life with her now-grown son. Above all, however, she loves being out and about—especially when the path leads along the Rhine.

Tanja enjoys spending her free time outdoors—preferably exploring Cologne on long walks that often take her through different neighborhoods, parks, and streets. For her, it’s the best way to truly notice the city’s details. She’s always curious to discover new cafés and restaurants, preferring to form her own opinion rather than sticking to familiar spots. That said, one place stands out: Einspänner in Cologne’s Südstadt, where she swears by the best latte macchiato.
