Always-On A/B Testing & Landing Page Optimizer

An AI agent that continuously writes, deploys, and tests landing page and ad variants, keeping only the winners — sold as a retainer service or SaaS.

▶ WATCH THE SOURCE SEGMENT — Karpathy's "autoresearch" broke the internet

01 THE IDEA

This business takes the auto-research loop and applies it specifically to conversion rate optimization: the agent generates headline, layout, and offer variants, routes live traffic to them, measures conversion rates, and iterates automatically. It's the spiritual successor to tools like Optimizely but powered by autonomous AI that generates and tests its own hypotheses rather than requiring marketers to manually design experiments.

The business model is flexible: sell it as a $5K/month agency retainer where the founder delivers monthly winning landing pages to clients, or build it as a SaaS tool businesses license. The agency model is fastest to revenue and validates demand before productizing. The core insight is that most businesses run 3-5 A/B tests per year; this system runs hundreds, compounding the optimization advantage dramatically.

03 THE VERDICT

CRO has proven, durable demand and businesses pay well for measurable revenue improvements. The AI-autonomous angle is a genuine leap over existing tools. Start as an agency retainer to validate and fund the product build. The '100x more tests' pitch is a memorable differentiator that closes deals.
