How We Turned a Vibe-Coded SEO Experiment Into An Automated Content Engine
For CrossEven, a Chicago-based holding company behind multiple telehealth marketing brands, growth had become expensive. The answer was organic acquisition, and that's where we, EnactOn, came in: turning a promising internal AI tool into a stable, scalable platform.
Clients that have trusted us over the years
When Lowering CAC Became a Software Problem
CrossEven needed a way to make organic acquisition scalable without creating another expensive stack or another full-time maintenance job. Four problems stood in the way of that.
Paid Acquisition Costs Keep Rising
Telehealth is a crowded market. As more competitors bid on the same terms, paid acquisition became increasingly expensive. The businesses needed a channel that compounds over time.
Too Many Tools, Manual Hand-offs
Replacing that stack meant roughly 6-7 different products costing over $3,000-4,000 per month. Zapier added maintenance and manual steps. Betting on one vendor backfired when it pivoted.
Cortexx Worked. Until It Didn't.
It was a strong proof of concept, but wasn't built on the engineering foundation needed for multiple brands. As it grew, something broke almost every other day.
No Room for Telehealth Guesswork
Unsupported medical claims create serious search and compliance risks. Publishing 10-15 pages a day meant it couldn't generate more content. It had to generate the right content.
We Took What Worked And Made It Even Better
Kevin Fairbanks had already proven that the idea could work. Our job was to give it the engineering foundation it needed to scale rather than replace it entirely.
One Flexible Multi-Model AI Layer
We moved the AI architecture to OpenRouter, working across multiple models through a unified integration, and added an image-generation router too.
From Prompts to Agentic Workflows
We rebuilt around specialist AI agents. Instead of asking AI to do everything in one shot, we gave it a process.
Uncovering What Customers Ask
Cortexx creates AI personas representing potential customers, then asks multiple models what they would search for. Those questions become content opportunities.
Every Piece Must Earn Publication
Before turning an idea into content, Cortexx checks existing pages for cannibalization, researches competitors and evaluates whether it adds something new.
Learning From Human Feedback
Experienced SEO specialists and writers review output, and their natural-language feedback becomes part of Cortexx's context. A human review layer remains.
WordPress and Astro, One Platform
Astro has no built-in CMS, so we added CMS capabilities to Cortexx while maintaining WordPress compatibility. Cortexx could support the migration.
From a Cost Problem to a Scalable Acquisition Engine
Cortexx started as an internal experiment. It's now a multi-tenant platform supporting 13-14 brands, hundreds to thousands of articles and millions of impressions across search and AI.
From 20-Person Content Operation to 4
At its peak, the operation involved roughly 20 people. Today, around 3-4 people operate the multi-brand content engine with Cortexx handling research, ideation, drafting, optimization and publishing.
Millions of Search and AI Impressions
Organic visitors feed retargeting, which costs roughly one-tenth of search advertising, with reported conversion around 6 to 7%, versus an industry benchmark of approximately 0.3 to 0.4%.
Lower Costs and a Profitable Business
Organic acquisition costs close to zero once content is published. The client reports some products grew from under 100 to 1,000-2,000 conversions per day over a year.
Cortexx itself is an internal growth platform, so these figures describe the broader business outcomes associated with CrossEven's acquisition strategy rather than direct revenue generated by the software.
Why This Was a Perfect Fit for EnactOn
Cortexx sat at the intersection of SEO strategy and serious software engineering, disciplines that rarely live under one roof. CrossEven understood SEO. It needed an engineering partner.
AI Engineering
We transformed a single-model AI experiment into a flexible, agentic architecture with persistent context, specialist agents and multi-model access, built for multiple brands in production.
SEO + AEO + GEO
The platform was built around how people discover information today, across traditional search engines and AI systems, rather than relying only on conventional keyword-volume data.
Scalable Platforms
What began as a tool for one brand became a multi-tenant platform supporting 13-14 brands, with architecture designed around repeatable workflows, not one-off fixes.
Marketing Tech
It sits inside a marketing operation, so every decision had a business reason: lower CAC, faster content production, better visibility, fewer tools, less manual work.

From a CAC Question to a Complete Organic Growth System
Cortexx started with one question: How do we reduce customer acquisition cost? The answer was an acquisition engine that could learn, create and scale. The work isn't finished.
