Built with founders across
Every unicorn once started in a studio.
A few people, and one relentless idea.
But buyers no longer search. They ask.
And if the answer never names you, you do not exist.
Let us make you the one it recommends.
Every month, globally
new companies launch with no effective go-to-market plan.
new Indian startups do exactly the same, every month.
the real reason startups fail is go-to-market, not product.

The shift
The AI boom created this problem. It has not solved it.
Discovery has moved. Buyers once searched and scrolled; now they ask, and an answer engine decides which handful of companies are worth naming. Most venture- and PE-backed companies have no strategy for being found or cited there.
And the tools that exist stop at the score. A tracker tells you that you are invisible, then hands the work back to you. Most companies do nothing and lose ground to competitors already in the answers, or bolt together a dashboard, an SEO agency and a freelancer that never coordinate. The result is a number that never moves.
Do nothing
Visibility erodes to competitors already cited by AI.
Point solutions
Three vendors, three roadmaps, no shared accountability.
One tracker
A dashboard shows the score but leaves the work to you.
The old way
A tangle of vendors. No one accountable.

The model
One platform runs the whole visibility loop.
Not a dashboard that stops at the score. Cailyx measures, diagnoses, fixes and proves, as one system, so the number actually moves.
Track
See exactly how ChatGPT, Perplexity, Gemini and Google AI Overviews describe and rank you, scored and tracked over time across the prompts your buyers actually ask.
Diagnose
Cailyx finds why you are missing: entity gaps, thin or unreadable content, and missing citations, then tells you what to fix first.
Fix
Agentic workflows build the entities, content and citations that move the score. Cailyx does the work, not just the report.
Prove
Every change ties back to citation share, pipeline and revenue, so you can see what visibility is actually worth.

The compounding advantage
“Every company Cailyx works on adds to a proprietary library: what AI sees, what we changed, and what moved. It is not patentable. It compounds like it is.”
Owning the whole loop is not just cleaner to buy. It compounds. What Cailyx learns making one company the answer makes the next one faster, and that library cannot be replicated by a dashboard or a blog post.
The product
Cailyx, our agentic AI-visibility platform.
The product we are building: it maps how AI sees you, builds the entities and citations that move visibility, and tracks citation share across engines. A Cailyx MCP is on the roadmap.
Also from Rothenhall · Free tools
Two things we built for founders. Use them free, no account.
What is Rothenhall?
Rothenhall is a startup building Cailyx, an AI-visibility platform. Cailyx tracks how AI assistants like ChatGPT, Perplexity and Google AI Overviews see your company, diagnoses why you are missing, and does the work to fix it.
What is Answer Engine Optimization (AEO)?
Answer Engine Optimization is the practice of getting a company named and cited in the answers generated by AI engines like ChatGPT, Perplexity, and Google AI Overviews, rather than only ranking in a list of search results.
How is AEO different from SEO?
SEO optimizes to rank in a list of links. AEO optimizes to be the source an AI answer names and cites. It focuses on entities, citations, and quotable, well-structured content that models pull into their responses.
What is Generative Engine Optimization (GEO)?
GEO is optimizing content and entities so generative AI models surface and cite your brand in their generated answers. Cailyx treats AEO and GEO as one AI-visibility discipline.
Who is Cailyx for?
Founders and teams who need to be found and recommended by AI assistants: startups, scale-ups and the agencies that serve them, in India and worldwide.
How do plans work?
Start free with an AI Visibility Score, subscribe to Cailyx for continuous tracking and prioritised fixes, or add managed execution where our team runs the work with you.
How does Cailyx measure results?
By AI citation share across ChatGPT, Perplexity, Google AI Overviews, Google AI Mode, Gemini, Google Search, and Copilot, plus the pipeline and conversion that visibility drives.
Is Cailyx available outside India?
Yes. Rothenhall is India-first and Cailyx works for companies worldwide.
Proof, not claims
Credibility here is earned in before-and-after, not bought in ads.
Founders trust demonstrated results. Our marketing is the work itself: documented before-and-after showing what changed in the answers, and what it was worth.
