How it works
Give a signup. Earn a signup.
Sign4Sign is directly reciprocal. Every verified signup creates a return obligation with a deadline, earns credits, and moves you up the founder levels.
The exchange flow
- 01
Create an account
Sign in with email or Google and set up your founder profile.
- 02
List your project
Add your product, its URL and a short signup checklist. You need an active project to take part.
- 03
Browse another founder's project
Find a product you are genuinely curious about in the marketplace.
- 04
Sign up genuinely
Open their site, create a real account and complete every requirement.
- 05
Submit confirmation
Return to Sign4Sign and submit the account you used, plus a screenshot if required.
- 06
The founder verifies it
They confirm or reject your signup with a reason.
- 07
A return obligation is created
Once verified, that founder must sign up for your project within 72 hours.
- 08
They sign up for you
You verify their signup, the exchange completes and both of you earn credits.
