About Stackgap

S

Stackgap

StackGap sells lead lists of local businesses whose websites have no live chat

StackGap sells lead lists of local businesses whose websites have no live chat widget. Pick a niche and a city (e.g. dentists in Austin), choose how many leads you want, and get a CSV in your inbox within 24 hours. Every business on the list has been checked: we load its website and look for known chat tools like Intercom, Tidio, Crisp, LiveChat, Chatbase, Drift, Zendesk and HubSpot chat.
