Business description
A finished SaaS that solves “slow pages” at the root.
■ The Problem This Service Solves
There are countless ways to improve your Google PageSpeed score. But no matter how much you raise the score, the experience of “waiting for the page to load” every time you click a link never goes away.
This service takes a fundamentally different approach. The moment a user hovers over a link (or, on smartphones, the moment a finger touches the link), it begins loading the next page in the background. By the time of the click, loading is already complete, bringing page transitions close to zero perceived wait. It is a new speed-up tool that focuses on “human perceived speed” rather than “speed on paper.”
■ Why This Business Will Grow Now
Google has adopted Core Web Vitals as an official ranking signal. On top of that, the new INP metric, which measures the speed of page interactions, has been added, and the bar for site speed grows stricter every year. Almost no SaaS in Japan specializes in this field, so you are positioned to capture the market as a first mover.
■ What Is Transferred
This listing is not just an idea but a transfer of a “working finished product.”
· Live in production
· Stripe payments, subscriptions, cancellation, and billing management implemented
· Google login authentication and user management implemented
· Core Web Vitals measurement dashboard implemented
· Admin user-management screen implemented
· Installation guide for WordPress included
· Specified Commercial Transactions notice, privacy policy, and terms of service all in place
· A domain officially indexed by Google
Building an equivalent system through an engineer would cost over ¥1 million in development alone.
■ Revenue Model
A monthly subscription model. You gather users on a free plan and monetize through conversion to paid plans.
· Pro plan: ¥980/month
· Business plan: ¥9,800/month
· Enterprise plan: ¥49,800/month
It is a stock-type business where revenue stabilizes as paid users accumulate.
■ Current Status
Because it just launched, it has 0 users and ¥0 MRR. However, the infrastructure, payments, authentication, and admin screens are all complete, so after purchase you can focus on customer acquisition right away.
■ Who This Suits
· Web-production companies and SEO consultants (can offer it as a value-add service to clients)
· Side-business and solo developers (those who want to improve and repurpose the finished code)
· Those considering entering the SaaS business (can reduce the build effort for infrastructure, payments, and authentication to zero)
It is perfect for those who have tried various measures to speed up page display and wondered whether there was anything more they could do.
I have multiple past M&A experiences, so when you purchase, I will do my best to hand it over as smoothly and quickly as possible.
I will also handle pre- and post-handover adjustments and fixes as flexibly as possible.
Please at least take a look at the landing page! If you have any questions, feel free to get in touch!
