Self-founded companies

We identify opportunities at an early stage and use them to develop our own business models.

Together with strong teams, we build businesses and support them with entrepreneurial experience, strategic resources and long-term capital.

fahrrad.de

Originally founded in 2003, we have been systematically rebuilding fahrrad.de and Bikester since March 2024. Our focus is on sustainable and profitable growth, made possible by a high degree of automation and a deliberately lean, high-performing team. Outstanding employees are consistently driving our development forward.

At the heart of our business is a strong e-commerce operation, complemented by five specialist high-street shops. With over 11,000 products, more than 115 brands and over 1,000 orders per day, we combine digital efficiency with high-street expertise.

In this way, we are gradually developing fahrrad.de and Bikester into modern, high-performance platforms and actively shaping the future of digital bicycle retail.

JetApp

In 2017, the KOEHLER GROUP founded JetApp GmbH in partnership with Philipp Schlüren. JetApp is a digital platform for booking private jets, bringing together pilots, crews, aircraft and customers in one place. Thanks to strong growth and successful international expansion, the company has established itself in several European markets.

The global market for private flights (USD 17 billion) is large but highly fragmented and largely undigitised. Bookings are often still made in a cumbersome manner via email and telephone. The market therefore offers great potential for an e-commerce platform that digitally connects all stakeholders and enables more efficient booking processes.
