Chimpy was founded in Zurich in 2013 with a simple yet practical innovation: renting a power bank. The idea addressed a common everyday problem – running out of battery while on the go – and offered consumers immediate peace of mind. What made Chimpy distinctive from the start was the combination of a circular product model, the use of renewable energy, and instant accessibility directly at the point of sale. The service requires neither an app nor registration, making it a straightforward solution embedded in everyday retail environments. Early support from Diethelm Keller Group, which became involved in 2014, enabled Chimpy to scale from a pilot project in a few Zurich bars to a broad retail roll-out by 2016. Since then, Chimpy has developed into an established convenience product, effectively creating a new category. Today, the service is available in stores, vending machines, restaurants, and event locations. Chimpy now operates over 4,000 points of sale across Europe and serves thousands of users every day.

Travellers Autobarn is a global campervan rental and sales company, founded in Australia in 1993. From the outset, the company has aimed to make road trips accessible, flexible, and affordable for young, adventureseeking travellers. Travellers Autobarn’s initial innovation was its traveller-to-traveller model, which pioneered long-term rentals and buy-back options for campervans – offering transparency and freedom at a time when such services were still uncommon. Travellers Autobarn operates fleets of budgetfriendly campervans for rental and resale, tailored to the needs of independent travellers who value flexibility, reliability, and simple solutions. Today, the brand stands for uncomplicated road travel and the ability to explore at one’s own pace, supported by practical vehicles and straightforward services. Over more than three decades, Travellers Autobarn has expanded its operations across Australia, New Zealand, the United States, and Japan. Diethelm Keller Group first invested in Travellers Autobarn in 2018. The Group’s involvement has strengthened the company’s international foundations, while allowing it to remain true to its original spirit of exploration and its commitment to making road travel accessible to a new generation of global travellers.
