"Renting made easy"


Our Idea

Servicing a network of lending machines, LEIHBAR grants easy access to high-quality and durable everyday goods. Access to items the users rarely use but don't want to live without. The users are unburdened from the complex information they have to consider on purchase. They don't have to care about repair or recycling. Items are rentable at the machines via touch-display or via app.

A projector for the soccer worldcup or a rubber boat for the lake? LEIHBAR adapts the variety of goods for every machine to local and seasonal changes.

Damaged goods are returned to the producer. Thus, LEIHBAR offers an opportunity for a company-intern, sustainable ressource strategy.
