Evertune
Updated 2026-08-16Enterprise AEO/GEO measurement built by Trade Desk veterans. The AI Brand Index runs more than 100,000 prompts per report across nine AI engines for customers including Canada Goose, Miro, Roku, and WPP Media's Choreograph. $19M raised. Recent launches: AI Retargeting, Visibility Boost, and Shopping Intelligence.
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 measures how brands show up in AI answers when the brand is not named in the prompt. Its AI Brand Index scores category questions like "what's the best espresso machine under $200" across nine surfaces (ChatGPT, Gemini, Claude, Perplexity, Meta, DeepSeek, Copilot, Google AI Overviews, and AI Mode), running more than 100,000 prompts per brand report. The output resolves to three numbers: a Visibility Score for how often the brand appears, an Average Position for where it lands in the answer, and a combined AI Brand Score.
The angle is adtech. The founding team came out of The Trade Desk, and through 2026 Evertune extended from measurement into activation. Partner Connect surfaces AI visibility data inside impact.com and PartnerStack for affiliate and B2B partner campaigns. Integrations with Index Exchange and The Trade Desk turn the publishers cited in AI answers into programmatic retargeting inventory. Shopping Intelligence tracks product recommendations in ChatGPT's structured shopping channel, and Visibility Boost buys ChatGPT ad placements against the queries where a brand's organic visibility is weakest.
Evertune's category POV is sample depth over prompt breadth. CEO Brian Stempeck argued publicly, naming Profound, that asking 100 unique prompts once each returns a visibility score with a ±9 point margin of error, while repeating each of those prompts 100 times narrows it to ±1. His point is that only the tight interval supports the topic-level decomposition a brand can actually act on.
Best for
Enterprise brand and media teams that want statistically tight AI visibility measurement and intend to act on it through paid, affiliate, and programmatic channels.
