#2 avg. position

+34 ahead of Salesforce

Zendesk is the clear first call for enterprises over 5,000 employees, appearing in every single answer across all twelve responses with a slot score of 90.

No other platform comes close to Zendesk's consistency here: 100% mention rate, average position 2, and uniform coverage from ChatGPT, Gemini, and Perplexity alike. Salesforce is the only real challenger, but its reach is uneven — Gemini surfaces it in all four of its answers while ChatGPT mentions it just once, and its average position of 1 reflects placement in a narrow slice of responses rather than broad dominance. The answers themselves point to compliance depth (SOC 2, HIPAA, FedRAMP) and high-volume workflow customization as the reasons Zendesk holds this ground at enterprise scale. ServiceNow appears in 67% of answers but sits at average position 4, making it a supporting option rather than a genuine rival for the top recommendation.

Slot score is position-weighted, 0 to 100: being recommended first counts far more than a trailing mention. "Appears in" is the share of answers naming the brand at all.

How this was measured

ChatGPT, Perplexity, and Gemini each answered this question in two phrasings, several times each, with live web access and citations: the closest API-reachable version of the real assistant experience (no personalization or account memory, which no vendor can provide). Model-memory answers (no web) are measured separately and shown above as a comparison surface. A brand counts once per answer that recommends it. The exact questions:

• "What's the best customer support software for a large enterprise with over 5,000 employees?"
• "We're a large enterprise with strict security, SSO, and procurement requirements. Which customer support software should we use?"
