One job in three movements. Rank you on Google. Get you named by AI. Convert the visitor who arrives.
AI engines cite the brands Google already ranks. We do the page-one work that earns both. Technical depth, the pages your buyers actually search for, the signals that put you on Google AND inside the AI answer. Same work, two surfaces. Then we layer the citation work on top for an additional AI boost.
Page-one ranking gets you in the door. The citation work is the layer on top. Comparison content AI engines pull from, AI-shaped explainers, citation sources, structured data. The work that lifts you from cited-occasionally to named-by-default across ChatGPT, Claude, Perplexity, and Gemini.
Traffic without a signup is a vanity metric. Every Google ranking and every AI citation lands on a page engineered to do the work after the click. Bottom-of-funnel landing pages, demo flows, signup forms designed to convert the intent we earned.
We do the work this quarter. Buyers find you in months. And keep finding you for years.
More buyers find you on Google. More AI engines cite you. More of both turn into signups.
Every page is built for the exact query a buyer runs. Not your category broadly. The specificity is the work.
Google and the AI engines move together when the same team runs the work. No second vendor. No second strategy.
Liam runs the account directly. No middle layer. No junior handoff. The strategist who writes the plan is the one who ships it.
Traffic pulled from Google Search Console and Ahrefs. Revenue reported directly by the businesses.

Hedra is an AI video generation platform in San Francisco that raised a $32M Series A from a16z. After their 2024 organic peak, the site was sliding through 2025 with no library built for buyer-intent queries. The 66th rebuilt the page architecture across bottom-of-funnel landing pages, middle-of-funnel comparison content, and AI-search-shaped explainers. In four months, the result was a 149% lift in organic Google revenue, a 354% lift in revenue from AI search, and a 399% lift in the purchaser rate from organic Google.

We map the queries your buyers and developers actually run on Google and inside ChatGPT, Claude, Perplexity, and Gemini. You see exactly where your AI startup is showing up today, where the gaps are, and which queries the category leaders have not yet locked down.
We ship the bottom-of-funnel pages your AI buyers search for, the comparison content AI engines cite, and the technical foundation that lets both compound. This is where AI startup growth stops being a roulette wheel and starts being a system.
Rankings climb. AI engines start naming your AI product when a buyer or developer asks. Both surfaces feed pages engineered to turn intent into a signup. We report every month so you see what is working, and we double down where it counts.
AI does not crawl like Google. It selects from what it trusts. We engineer your brand into the sources ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews, and Copilot pull from so that when a buyer or developer asks, they find you.
Six surfaces. One engagement. The same content layer feeds them all.
