Evertune
Updated 2026-05-31An AEO/GEO platform whose AI Brand Index measures how often brands surface in AI answers to category questions where they aren't named, across nine engines. Customers include Canada Goose, Miro, and Roku. $19M raised. Recent moves: a Visibility Boost ad agent for ChatGPT, a Gartner Market Guide listing, and AI retargeting partnerships.
Three scores, refreshed weekly from live market signals rather than a once-a-year analyst report. Presence is how established a vendor is in the market right now. Velocity is how fast they are shipping, raising, and winning customers. Agent Readiness is how easily your own agents can build on them through an API, MCP server, SDK, or CLI. Scores are relative across the vendors we track; the raw inputs ship in the downloadable dataset.
The Solution & Approach
Evertune is an AEO/GEO platform built around the AI Brand Index, which ranks how often and how prominently a brand surfaces in AI answers to category questions like "what's the best espresso machine under $200" when the brand is not named in the prompt. It tracks nine AI surfaces, including ChatGPT, Gemini, Claude, Perplexity, Meta, DeepSeek, Copilot, Google AI Overviews, and AI Mode, and runs more than 100,000 prompts per brand report. The Index resolves to a Visibility Score, an Average Position, and a combined AI Brand Score.
The company's angle is statistical scale plus an adtech pedigree. Felicis contrasted Evertune's 100,000+ prompts per report against competitors that "prompt the model just a handful of times," and the founding team came out of The Trade Desk. Recent metrics work, Topic Relevance and Brand Relevance, pushes past raw citation frequency to measure which source URLs actually influence how AI models understand a category, with one internal analysis finding the most-cited source ranked 33rd in real influence.
Evertune's distinct POV is moving from measurement into media activation. Through Partner Connect it has wired GEO intelligence into affiliate (impact.com, PartnerStack), programmatic (Index Exchange, The Trade Desk), and structured shopping channels, and its Visibility Boost agent buys ChatGPT ad placements targeted at queries where a brand's organic AI visibility is weak. It is the first tracked AEO vendor shipping a paid-placement agent on top of its measurement layer.
Best for
Enterprise and adtech-minded marketing teams that want statistical-scale measurement of unprompted AI brand visibility and a path from measurement into affiliate, programmatic, and paid-placement activation.
Pricing & trial
Sales-led; not publicly listed, with a third-party comparison putting it around $36K/yr, and no public free trial.
Agent Experience
How you build on this platform (or wire it into your own agents):
| Surface | Available | Docs |
|---|---|---|
| API | No | — |
| MCP | No | — |
| SDK | No | — |
| CLI | No | — |
| llms.txt | No | — |
Weak as a build-on platform: the docs are a thin help center with no public API reference, so its agent surface is the productized Visibility Boost ad agent rather than developer tooling.
Reference customers
Canada Goose, Miro, athenahealth, Roku, Virgin Voyages, HexClad, WPP Media (Choreograph).

Company, Financials & Funding History

The team applies its adtech pedigree to AEO/GEO, extending from measurement into media activation.
