Zendesk vs Intercom

Zendesk leads broadly; Intercom still owns the startup conversation. Zendesk's 78 visibility score versus Intercom's 60 reflects a 21-point naming-rate gap, driven by dominance on enterprise and use-case fit questions where buyers signal serious purchase intent. ChatGPT is the sharpest separator: it scores Zendesk at 87 against Intercom's 57, a 30-point gulf that Gemini and Claude never fully replicate. Intercom's one durable foothold is the startup and small-team question theme, where its conversational positioning still earns the first-pick nod over Zendesk.
