Business description
Thank you for viewing this listing.
This is a business transfer of a web application that provides an “LLMO (Large Language Model Optimization) score diagnosis” for the next generation of search experience.
[Site Overview and Background of the Transfer]
Recently, not only conventional Google search (SEO) but also AI-based search and answer generation by tools like ChatGPT and Gemini is becoming mainstream. This app is an innovative tool—essential for the era ahead—that diagnoses how correctly a target website is read and how easily it is evaluated by AI.
Basic development and internationalization (multilingual support) are already complete, and it currently runs stably on Vercel. However, my own resources have been taken up by another business, and I can no longer secure any time to promote this app or carry out ongoing operation and feature additions.
Since the system itself is complete, rather than letting it go to waste, I would like to pass it on to a company or individual who can make the most of this tool’s potential for their own business.
[Selling Points / Who This Is Recommended For]
This is a product I can strongly recommend especially to existing SEO firms and web-production/marketing companies.
As a powerful hook (lead-generation) tool for an existing business
By offering this LLMO diagnosis for free on your own site or owned media, you can use it as a tool to acquire leads from “highly engaged companies interested in the new SEO of the AI era (LLMO).” It pairs excellently as a supplementary service to existing SEO consulting, or as a door-opener tool.
A modern, easy-to-hand-over tech stack
The system is built on a modern configuration (GitHub + Vercel, etc.), is very lightweight, and is easy to maintain. Because there is no reliance on any specific person, any web engineer can quickly integrate or customize it into your own environment.
A foundation for multilingual support and monetization
Because it is already internationalized, you can consider not only the domestic Japanese market but also global expansion. Currently a “Buy Me a Coffee” (tipping) link is set up on a trial basis, but you can also use it as a base to develop into a paid plan (SaaS) with feature limits in the future.
[Negative Information / Current Status]
· Currently it is stopped at the stage of having published the system; because no active customer acquisition is being done, there is no traffic or revenue (this is a completely pre-revenue listing).
· Please consider this not a transfer of operating track record or customer lists, but purely a “transfer of the system and rights to a completed web app.”
[What Is Transferred]
· The domain
· The full source code (transfer of the GitHub repository)
· Handover of Vercel project permissions
This is an app addressing a highly promising theme as a next-generation web-marketing tool. We look forward to hearing from those who can use it for a new venture or as a powerful supplementary tool for an existing service. If you have any questions or concerns about the technical handover, please feel free to ask.
