Les Petites Pierres
Les Petites Pierres is a crowdfunding platform, also known as solidarity-based participatory financing, dedicated to fighting substandard housing. Founded in 2013, it lets nonprofits submit concrete housing-related projects (renovation, construction, access to housing, emergency shelter...). Each project is reviewed by a verification committee to ensure it fits the platform's scope and addresses real needs. Once approved, projects are opened to the public. Donations collected are matched by Les Petites Pierres thanks to its partners' support, multiplying the impact of every contribution. For over 10 years, the platform has redistributed more than 9 million euros and supported more than 600 nonprofits across France.
