Background

Evertune is the marketing platform for brand discovery in AI search. The platform analyzes prompts and prompt responses at scale across all major LLMs (ChatGPT, Gemini, Claude, AI Overviews, AI Mode, Perplexity, Copilot, Meta AI and DeepSeek) to deliver statistically significant insights and translate them into specific, executable actions across owned, earned, affiliate and paid media. With Evertune, brands can own the AI customer journey.

Evertune was founded in 2024 by early team members of The Trade Desk, who helped build the company from startup to $50B+ market cap. The company is headquartered in New York City and has raised $20M from leading adtech and martech investors. Evertune has been featured in the New York Times, Wall Street Journal, The Economist, The Information, Axios, Forbes, Reuters, AdWeek and AdAge.

Evertune's core position: AI is a growth channel to own. The brands building GEO capabilities now are shaping how AI understands their entire category. But organic GEO visibility takes time. While brands work to improve their organic visibility, they can use Evertune's ad products to appear in the AI conversation and beyond, through contextual and audience retargeting.

Proprietary methodologies and data sources

Direct API access. Evertune measures how the base LLM model perceives a brand before any live search influences the response. This reveals foundational AI biases within a category and shows how brands perform in the knowledge layer that powers AI agents.

Consumer app data collection. Evertune also captures what AI finds in real time when live search is enabled. The delta between foundational knowledge and consumer app responses reveals how effectively a brand's SEO influences AI model outputs.

EverPanel. Evertune's proprietary consumer panel of 150 million prompts, demographically weighted to reflect the broader internet, shows what real users are prompting across a brand, category and competitive set, including the language they use and how frequently they search.

Perspective

Evertune believes AI search is a growth channel to own. The customer journey has fundamentally changed. Buyers now discover brands, research categories, compare competitors and make purchase decisions through conversational AI. A brand either shows up in those conversations or it doesn't exist in the consideration set.

Evertune is built specifically for this moment: not a retrofitted SEO tool, but a platform founded in 2024 for how LLMs select, rank and recommend brands. From insights to activation, Evertune tracks real AI search behavior, improves organic visibility through GEO, creates content built for AI education, and advertises to buyers in and beyond the AI conversation.

Typical clients

Evertune works with mid-market and enterprise brands across Finance, Retail and E-Commerce, Automotive, Pharma, Technology, Travel, Food and Beverage, Entertainment, CPG and B2B. Current clients include Halo Collar, Canada Goose, HexClad, Roku, and WPP.
