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 76 and the #1 spot in 36% 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. The live-web grounded surface is rolling out across the index. Methodology.

Apollo owns the default slot; everything below it is contested.

Apollo.io leads with near-universal mention across all three models and takes the first-pick position 36% of the time, a gap that makes it the obvious default answer in this category. Salesloft and Outreach split the runner-up story in an interesting way: Salesloft scores higher overall but Outreach wins first-pick honors 29% of the time, suggesting Gemini's weak score of 42.5 for Outreach is masking genuine top-of-mind strength on the other two models. Lemlist sits at the bottom with a 25.1 score and zero first-pick mentions, meaning it gets included for completeness rather than recommendation.

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: Reply.io (3.5), Regie.ai (3.3), Lavender (3.3), Mixmax (3.2), Artisan (2.9). 70 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.
