Companion is a banking service aligned with the special needs of shared living communities. A lot of people live in shared flats as it offers numerous benefits. Even though the motivation to move into a shared flat is as different as the people who live in them, it is apparent that sharing goods supports a good atmosphere and vice versa. Companion supports this reciprocity by providing a flexible solution every shared living community can adapt to their needs.

The service consists of a bank-account, a web- and a mobile application and physical tokens, the companions themselves. The bank account can be used to collect monthly contributions to do regular payments like rent, electricity and internet and to save money for other shared expenses.

Each tenant owns one companion, that is recognizable by a color chosen before. The companions visualize the shared flats financial situation in a simplified way: If there are debts amongst the flatmates, if one tenant is very successful in saving money for the community or if the shared accounts balance is growing or getting smaller.

As the companions are placed in the shared space of a flat, they become a part of everyday life, supporting the sharing and saving behavior by using the rules the tenants agreed upon.
