In the Spotlight:
Karsten Wulf and zwei.7

People are what make the difference for us. Because relationships work best when they are based on mutual trust and reliability. The cooperation between us and our partners thrives on respect and appreciation for one another, a shared sense of responsibility, and a high level of discretion.
We also believe in taking a positive and open professional attitude as well as bringing enthusiasm and passion for growth to everything we do.

The Basis for Our Success​:
Respect and Appreciation for
One Another, and a Shared
Sense of Responsibility.

Company Values that Shine:
Those who wish to lead must enjoy people!

We believe in the power of value-oriented leadership combined with a company culture that is lived out, rather than just written down. Living out these values means taking responsibility – in other words, leadership is not about positions, job titles, tools, or status: it is a question of mindset and commitment. Strategy, including a vision and a mission, defines what direction growth will take.

Karsten Wulf, Entrepreneur

Karsten Wulf, founder of the zwei.7 Group, started his entrepreneurial journey while still in school. At 16, he founded Microchip GbR, which sold hardware and software, as well as a service and repair company for Commodore computers in 1989.

He achieved his greatest commercial success while studying Business Administration with the founding of the buw Group in Osnabrück in 1993. With just 1000 DM in startup capital, a nose for new opportunities, and heavy doses of passion and perseverance, he built up one of the largest customer-care & BPO service providers in Europe. By 2016, the buw Group had achieved a turnover of €161 million, working with customers such as Vodafone, Miele, BMW, SAP, and Roche, and employing over 6,000 personnel at 14 sites in Germany, Romania, and Hungary.

Karsten Wulf has been honored with numerous prizes including the “Entrepreneur des Jahres (Entrepreneur of the Year),” the second-fastest growing company in Europe (Europe’s 500), the TOP Job Arbeitgeber (TOP Job Employer Award), and the HR Excellence Award. He is the Chairman of the Advisory Board of Ossenberg Holding, and a member of the Advisory Board for the Osnabrück Healthcare Accelerator (OHA).

The Founding of the zwei.7 Group

The robust expansion of the buw Group led to the creation of numerous new sites, but these were always rented. In 2012, however, the opportunity arose to acquire the company headquarters of the largest site, in Leipzig. This allowed Jörg Hänscheid and Karsten Wulf to lay the cornerstone for zwei.7’s real-estate business.

Nonetheless, the decisive turning point for Karsten Wulf came during a family vacation to the Antarctic in 2016. Again on the hunt for new challenges, confronted with the growing role of digitalization and internationalization in the customer-care industry, and fascinated by the shimmering blue of the Antarctic ice, he resolved to stake out a new path. That same year, Karsten Wulf and his partner Jens Bormann successfully sold buw to a large, NYSE-listed American corporation. This marked the first time that Karsten Wulf completed the founding, successful expansion, and exit of an enterprise.

A Name That Radiates

Karsten Wulf’s decision to start out on a new path was tightly bound up with his impressions of the shimmering blue light of the colossus of ice that gleamed as the sunlight hit it. The energy released by this radiation amounted to 2.7 electronvolts; this became the namesake of the new company. Just as the sunlight brings ice to light, zwei.7 hopes to bring values to light, and show them to the world.

Engagement for the Good Things in Life

Our understanding of values is not just limited to the workplace – social engagement is a major interest of our team, not least for our founder, Karsten Wulf.

Annual fundraising drives for kindergartens at Christmastime have become a joyful tradition at zwei.7. Another important topic for us is support for Wunderbunt e. V. This Osnabrück-based organization offers parents of children with disabilities a chance to listen, a chance for advice, and a chance to exchange ideas. Since 2017, zwei.7 has also closely partnered with HelpAge. HelpAge is an Osnabrück-based charity committed to assisting older people in developing and emerging countries. Karsten Wulf has served as an Ambassador for the organization, and annually hosts a large dinner, with the proceeds going to HelpAge.
