About the company

Joko operates a mobile shopping app that gives users cashback, coupons, and discounts from a wide range of retailers. It earns commissions through affiliate marketing when users make purchases via the app. The app is free for users and automatically calculates the carbon footprint of each transaction, encouraging more conscious consumption. How it works: users browse partners in the app, activate deals, and make purchases through affiliate links to get rewards; the platform tracks sales and credits cashback automatically to the user’s account. How it is different: it combines traditional cashback and coupon offers with real-time carbon footprint insights for each purchase, offering environmental visibility alongside savings, within a broad consumer market. What the company aims for: to help people save money on everyday spending while promoting greener consumption and to grow its affiliate network across retailers.
