Evertune

The Solution & Approach

Evertune measures how brands show up across AI engines when they aren't named in the prompt. Its flagship AI Brand Index ranks how often and how prominently a brand surfaces in answers to category questions like "what's the best espresso machine under $200," tracking nine surfaces (ChatGPT, Gemini, Claude, Perplexity, Meta, DeepSeek, Copilot, Google AI Overviews, and AI Mode) and running more than 100,000 prompts per brand report. The Index resolves to three scores: a Visibility Score, an Average Position, and a combined AI Brand Score.

The founders came out of The Trade Desk, and that adtech pedigree shapes the angle. Where most AEO tools stop at measurement, Evertune has extended into media activation, connecting its visibility data to programmatic and affiliate buying through Partner Connect and integrations with Index Exchange and The Trade Desk.

Its category bet is that measurement is only half the job. Evertune found that over 40% of the top 10,000 sources cited by AI models contain affiliate links or are sponsored, the data rationale for wiring AEO/GEO measurement directly into the channels that shape AI answers. Felicis backed it on statistical scale, contrasting Evertune's 100K+ prompts per report against competitors that prompt the model "a handful of times."

Best for

Enterprise marketing teams that want statistical-scale AI visibility measurement and a path from tracking into media activation across programmatic, affiliate, and paid AI placements.

Agent Experience

How you build on this platform (or wire it into your own agents):

Weak as a build-on platform: the docs are a thin help center of about six articles with no public API reference, so there is little to wire into your own agents today.

Reference customers

Canada Goose, Miro, athenahealth, Roku, Virgin Voyages, HexClad, WPP Media's Choreograph.
