Every year, microDON invites all its partners to report on the ARRONDI round-up at the register program.

In 2018, 1% of companies in France implement ARRONDI, and Maisons du Monde is one of them! For this new edition, all the partners were able to celebrate the 20 million micro-donations made since the start-up began operating!


microDON is a Social and Solidarity Economy start-up that develops innovative solutions to facilitate and promote social commitment. The solutions are designed to encourage and enable everyone to be an actor of change easily and at their own level.

The ARRONDI cash desk round-up scheme gives us the opportunity to educate our customers on the Maisons du Monde Foundation, and show them how they can make their purchases meaningful by donating and co-funding environmental and social projects such as forest conservation.

Selected during the 2018 call for projects, NGO’s receive support from the Maisons du Monde Foundation for a period of three years. Following the selection of six projects by the panel of experts of the Maisons du Monde Foundation, the company's employees voted for 4 associations to be supported by ARRONDI for the year 2018!

In 2017, thanks to the generosity of our customers we won  the prize for the best store participation rate in 2017 with 56% of participation. More than one customer out of two rounded up their purchases by a few cents. Thank you to our store colleagues for their dedication and our customers for their generous donations: this prize recognises the collaborative work of the community!

In 2018, another four projects were selected by the employees to be supported by ARRONDI for three to four months each, headed by the NGOs Envol Vert, Ishpingo, Tchendukua and AICO.
