Les Petites Pierres is a nonprofit crowdfunding platform dedicated to helping associations address poor housing and promote access to decent homes. It connects donors with carefully reviewed community projects, including housing renovation, emergency accommodation, inclusive living, support for people experiencing exclusion, and initiatives that build social connection through housing. A distinctive feature is its commitment to doubling donations, helping projects raise more while encouraging public participation.

The platform is free for associations and charges no commission, and participating organizations receive personalized support to develop and run their fundraising campaigns. Associations can present projects, share campaign updates, and reach potential donors through the platform. Les Petites Pierres also provides information for donors about giving and tax deductions, including fiscal receipts, and offers guidance for associations on eligibility and submitting projects.

Its work focuses on reducing social exclusion, supporting autonomy, combating energy poverty, and improving living conditions. Through crowdfunding and practical campaign support, Les Petites Pierres helps associations finance nonprofit housing projects and turn local solidarity into more dignified places to live
