We are Lester & César behind CSFN

Hello there! We are Lester and César, the passionate founders of CSFN. Initially, our journey began when César conceived the idea in 2018 while traveling Europe and litter picking in every place he’d go. Trash was everywhere! As the hashtag #cleansomethingfornothing went viral on social media, he saw the need for an app. In 2019, César met Lester, the tech mastermind behind the app. This moment marked a turning point for the project, and together, we joined forces to elevate CSFN to the next level, working hand in hand every step of the way.

Furthermore, we have been tirelessly improving and expanding CSFN. It is a magic feeling meeting lovely litter pickers across the globe, sharing ideas and listening to their needs. As a result, the CSFN app is making it easier than ever for individuals and communities to take action and keep our planet clean in an easy and reliable way.

As the founders of CSFN, we are committed to leading the charge in the global fight against litter and pollution. Our passion lies in empowering people to be the change they wish to see in the world. We also foster a community where every effort is recognized. Therefore, we are eagerly anticipating the future and the positive impact we can collectively make toward a cleaner planet.

Our mission & vision


At CSFN, we enable people to clean nature, one bag of trash at a time, through our innovative app. Our community-driven platform fosters collaboration between individuals, municipalities, and companies, all working together to create a cleaner and healthier environment for everyone. Each contribution, no matter how small, is a step towards our collective objective—a testament to the power of shared responsibility.


We envision a litter free world in a conscious and collaborative society. Together, we can create an environment where nature flourishes in its purest form, ensuring future generations inherit a cleaner and healthier planet.
