What AI voice share means for cold email infrastructure vendors
B2B buyers increasingly start vendor research in AI engines.

Vendors with high voice share get into consideration sets they didn't have to earn through ads or SEO.
This data is measured via standardized, context-free API calls — the same query sent to each LLM in a fresh session, repeated across 12 buyer-intent prompts. It represents baseline citation behavior, not personalized results.
