Sales Engagement & Outbound: AI Visibility Ranking

Platforms for outbound sequences, prospecting data, and multichannel sales outreach. Right now, Apollo.io is the brand AI assistants recommend most, with a Visibility Score of 79 and the #1 spot in 38% of answers. Head-to-head: Apollo.io vs Salesloft →

These rankings are measured from what the three models know from training, not a live web search. When the models DO search the web, see which sources they cite. Methodology.

Three models, three different leaders, no consensus here.

ChatGPT favors Salesloft and Outreach over Apollo.io, while Claude and Gemini push Apollo.io to the top, and Gemini drops Salesloft to 52.1 against ChatGPT's 81.7 for the same brand. That 30-point Salesloft gap between models is the widest single-brand split in the top three, which means a Salesloft win in one AI channel does not travel to another. Buyers relying on any single model will get a materially different shortlist than buyers who compare across all three.

The ± under each score is the reliability band: how much the number would move if we re-ran the identical measurement. It is tight because each prompt is sampled multiple times. It is not the same as how much the ranking depends on which prompts we ask — a separate, wider figure shown on hover.

Just below the cutoff: UpLead (3.5), Cognism (3.1), Amplemarket (2.9), Mailshake (2.8), Gong (2.8). 66 brands were scored in this category; the leaderboard shows the top 15.

Visibility Score: position-weighted presence across all measured answers, 0 to 100. A score of 100 means the brand was the first recommendation in every answer. Every point in a trend line is a live monthly measurement; there is no modeled or backfilled history. Full methodology.

Openness 21/100: the share of this category's recommendation weight not held by the leader.
