The Köster GmbH Group, a full-service construction provider in Germany, is bundling its start-up activities under the new umbrella of KÖSTER VENTURES with immediate effect. The aim is to actively drive innovation in the construction industry and help shape the transformation of the sector.

Focus on startup collaboration, investments and new business models

KÖSTER VENTURES arose from CEO and shareholder Nils Köster's desire to innovate. The unit focuses on three central areas of activity:

  • Startup collaboration: building a platform for founders that focuses on collaborative partnerships and practical projects.
  • Strategic investments: Investments that go beyond capital, including support with market entry and growth.
  • Development of new solutions: Validation of innovative approaches, creation of new business models and implementation in the market.

Practical implementation along the value chain

The activities of KÖSTER VENTURES focus on construction, planning, sustainability and sales. By combining operational experience and new technologies, start-ups are directly involved in real projects, allowing practical innovations to be implemented more quickly.

Scaling opportunities for start-ups through direct company integration

With over 85 years of industry experience and around 200 projects per year, KÖSTER VENTURES offers start-ups an environment for rapid scaling. The close connection to the board of directors and shareholders enables quick decisions, reduces bureaucratic hurdles and promotes partnerships and investments at a start-up-friendly pace.

Invitation to founders

KÖSTER VENTURES is aimed specifically at start-ups, founders and innovators who want to change the construction industry with new technologies. The goals are practical market introduction, partnership-based cooperation and sustainable growth.
