Selling chatbots or AI receptionists? StackGap finds your next clients: local businesses whose websites have no live chat. Pick a niche and city (dentists in Austin, roofers in Leeds). We check every site for Intercom, Tidio, Crisp, Drift, Zendesk, Chatbase and more, then email you a CSV of the ones with none. $1.20 per lead, paid once. No subscription, no $295/mo lookup tool. Bad leads replaced free.
