What Is a Signup Exchange?

A signup exchange is a simple agreement: I become a user of your product, you become a user of mine. ## Direct reciprocity Two founders, two signups, one obligation each. It is easy to understand and easy to verify. ## Credit-based reciprocity Some platforms use credits so value can circulate. It scales, but it also lets people accumulate without ever returning value to the person who helped them. ## Why Sign4Sign is direct Every verified signup creates a return obligation with a deadline. If you receive a real user, you owe a real user back. Nothing accumulates, nothing gets gamed. ## Quality still matters A signup only counts when it is a real account, created manually, that meets the requirements the founder published in advance.
