grinflow is a logistics layer that rescues surplus food. A restaurant or shop sends a message or a photo of what it cannot sell, on WhatsApp or the web. Muse Spark turns it into a structured offer, checks the photo honestly (it says when no food is visible), and an agent proposes where it should go: food banks, community kitchens, makers who transform it. Recipients hold part or all of an offer, a mission is closed by QR scan with a verified receipt, and impact (CO2 and water) counts only food that actually reached people. It includes organization accounts with data isolation, a map, and an installable PWA app.
