Most brands have no idea whether ChatGPT recommends them, ignores them, or gets them wrong. Gist — a subsidiary of ProRata, founded by Bill Gross, the entrepreneur credited with inventing the pay-per-click advertising model — launched Gist GEO on April 21 to close that gap.

The platform tracks and improves how brands appear in AI-generated answers across ChatGPT, Google AI Overviews, Gemini, and Perplexity. It is available now at gist.ai/geo.
The problem GEO is built to solve
Traditional SEO tells a brand where it ranks in search results. It says nothing about whether a brand gets cited, recommended, or accurately described when a buyer asks an AI assistant a question. That gap — between SEO visibility and AI visibility — is the market Gist GEO is entering.
The platform measures brand performance across six metrics: AI Mention Share, Share of Citations, Share of Citations Found, Share of Earned Media, Share of Recommendations, and Prominence. Those feed into four Brand Health dimensions — Awareness, Sentiment, Authority, and Recall — updated weekly with directional deltas and trend lines.
Features include an AI Visibility Dashboard, Brand Opportunity Reports, Competitive Benchmarking, Content Gap Analysis, and Strategic Recommendations. The Growth tier ($349/month) covers up to three brand profiles across four AI engines (ChatGPT, Perplexity, Gemini, and Google AI Overviews), with 300 basic tracking queries and 30 deep analysis queries per month. Basic access runs $99/month for a single brand profile, ChatGPT only, with 60 basic tracking queries and 5 deep analysis queries. Enterprise offers unlimited profiles, all AI engines, and custom query volumes at custom pricing. All new accounts start with a 14-day free trial on the Growth tier (credit card required).
Funding and backing
ProRata has raised more than $75 million since its 2024 launch, including a $40 million Series B. The company is partnering with top-tier publishers and positioning Gist GEO as part of a broader suite that includes publisher monetization tools. CMO Peter Sloterdyk is leading the go-to-market push; Gist discussed the launch at the GROW LA roundtable on April 22.
Gross, whose pay-per-click model reshaped online advertising in the late 1990s, is framing Gist GEO as a similarly structural intervention — this time for a world where AI answers are displacing the search results page entirely.
Where GEO fits in the emerging taxonomy
Gist distinguishes GEO from the related but distinct discipline of AEO (Answer Engine Optimization). In its framing: SEO determines where you rank in traditional search; AEO shapes how you appear in AI-generated direct answers; GEO ensures your brand is cited accurately and favorably within the AI narrative. The distinction matters because AI systems don’t just return results — they construct answers, and brands that aren’t structured for AI comprehension can be misrepresented or omitted entirely.
The platform’s “zero-click” framing captures the underlying pressure. AI answers increasingly appear above ranked search results, meaning users never visit a brand’s site at all. A brand that doesn’t show up in that layer may as well not exist for that query.
