Prospect List Providers
Companies that compile, curate, and sell targeted prospect lists across industries and roles for B2B outbound sales and marketing campaigns.
Apollo is the default answer in AI responses for Prospect List Providers
When users ask ChatGPT, Claude, or Gemini about Prospect List Providers, Apollo is the brand that surfaces first - unprompted, consistently, and usually at the top of any list the model generates. ZoomInfo is a close second, but the gap between them is meaningful. If you're competing in this space and you're not in the top handful, you're effectively invisible to AI-driven discovery.

How is this calculated? Methodology
Every brand in this leaderboard is scored against the same set of 299 shared Prospect List Providers prompts. The same prompts, same model, same iterations. So differences in scores reflect actual differences in AI visibility, not differences in measurement.
Overall AI Visibility Score
composite = ((LBA + 5)(Authority + 5)(TOM + 5))^(1/3) - 5. The floor keeps brands the model clearly recognises but doesn't yet recommend from collapsing to zero, while a single genuinely weak metric still pulls the composite down. Full methodology.

Latent Brand Association (LBA)
quality × meta × stability × share × recognition × 100. Read the full LBA methodology →
