SocialSign.in is a guest WiFi marketing platform that turns venue Wi-Fi login into a customer-acquisition and engagement channel. When guests connect to free Wi-Fi through branded splash pages, the platform captures opt-in contact data (email, phone, profile), measures visit frequency and dwell time, and syncs profiles to CRM and email/SMS marketing tools to trigger targeted campaigns across retail, hospitality, sports and entertainment, healthcare, and commercial real estate venues. It sells two products: the enterprise platform, sold through a contact-sales motion, and SocialSign.in Go, a self-serve packaged version with published per-location pricing. The company publishes no developer portal, no API reference, and no machine-readable specification of any kind; its product documentation lives in a public Zendesk help center covering portal setup and CRM/ESP connector configuration rather than any programmable interface. A JSON-emitting API root does exist at c.socialsign.in/api/ inside the authenticated customer console, and the Enterprise tier advertises "Advanced integrations" and a "Data mart", but neither is documented publicly.
