Description
Cosigned is a product discovery and social proof platform where people discover products and Cosign the ones they support. Unlike launch platforms where rankings reset after a launch, Cosigned keeps every Cosign as permanent social proof. Builders get a public product page, authentic support from verified accounts, community Reasons, and private visit analytics. Products become publicly discoverable after the Cosigned badge is verified on their website.
