Question: I want to find a platform that rewards users for contributing to a community-driven coupon code database.

If you like the idea of a platform that pays you for contributing to a community-driven coupon code repository, SimplyCodes is a good choice. This e-commerce site is community focused, with members earning tokens for contributing to the site that can be redeemed for cash or entered into "Grab Bags" for a chance to win more. The site also uses AI technology to harvest thousands of new coupon codes each day, then has the community vet them to make sure they actually work.

Another good choice is Karma, which tries to simplify online shopping by automatically applying promo codes and cashback rewards when you're checking out. You can earn more through cashback rewards, and the company has deals with more than 100,000 stores, so it's a good way to get a discount wherever you shop. With features like automatic coupon application, price tracking and instant product comparison, Karma is a powerful tool for the financially astute.

If you like the idea of community involvement and monetization, but want something more general purpose, check out Mighty Networks. The service lets people create, manage and profit from engaged communities, courses and memberships. It doesn't have anything to do with coupon codes, but its community-building abilities and payment tools could be used to build a system that rewards people for contributing coupon codes.
