Technical Partnership
Current Challenges
There is no future for websites left "as is".
A website isn't finished once it's launched. Technology evolves daily, and neglected sites quietly but surely turn into 'technical debt'.
Security Vulnerabilities
Invisible security risks. Vulnerabilities in libraries and frameworks are discovered daily. Code that was safe yesterday might be a target for attacks today. Without regular updates, safety cannot be maintained.
Technical Debt
Accumulating technical debt. The longer it's neglected, the more obsolete the code becomes and the harder it is to fix. To avoid situations where "a small fix" becomes impossible due to an outdated environment, it's essential to always keep things up-to-date.
No Tech Leadership
No one in the company understands technology. "Can we add this feature?" "How do we integrate AI?" Are you missing business opportunities because you have ideas but no one to make technical decisions?
Philosophy
Your External CTO.
Specialist perspective on technology's 'defense' and 'offense'.
Hiring a single excellent engineer requires an annual cost of over 10 million yen and a lengthy recruitment period.
However, for many companies, a full-time engineer isn't always necessary.
We participate in your company's web business as an "External CTO (Chief Technology Officer)".
We are not merely "maintenance workers".
From "defense" such as daily monitoring and updates, to "offense" proposals like technology selection and feature additions to grow your business.
We support your web assets from a technical, management-level perspective.
Maintenance Plans
Technical Insurance
¥30,000~ / month (tax excluded)
Minimum security insurance to protect your web assets.
24/7 automated monitoring to check if the site is down or generating errors. Additionally, we regularly update Next.js and npm packages to prevent security vulnerabilities. This is ideal for companies that "generally don't need active management, but want a reliable partner in case of an emergency".
Includes:
- Dependency Updates (npm/system updates)
- 24/7 Monitoring (Liveness and error monitoring with Sentry/Better Stack)
- Investigation Only (Initial troubleshooting and investigation for defects) *Fixes quoted separately
Best for:
- Corporate websites with infrequent updates
- Campaign sites
Technical Advisory
¥100,000~ / month (tax excluded)
Advisory and consulting contract supporting technical decision-making.
In addition to the contents of Technical Insurance, we offer unlimited technical consultations via chat tools (Slack/Chatwork). We provide immediate answers to questions like "Can this be implemented?" or "How does this feature work on other companies' websites?". We also allocate approximately 5 hours of work per month for minor code adjustments and detailed investigations.
Includes:
- Everything in Technical Insurance
- Chat Consultation (Technical consultation / Spec discussion brainstorming)
- Small Adjustments (Minor code adjustments/investigations up to 5 hours/month)
- Monthly Report (Access and performance reports)
Best for:
- Companies operating their own services
- Companies with web managers but no technical staff
Dev Partnership
¥300,000~ / month (tax excluded)
Dedicated engineering to accelerate business growth.
In addition to the Advisory contract, this plan secures approximately 20 hours of "development resources" per month. We continuously perform development necessary for business growth, such as adding new features, improving UI, and integrating APIs. This plan allows you to bring highly skilled, ready-to-contribute engineers into your team without incurring recruitment costs.
Includes:
- Everything in Technical Advisory
- Active Development (Commitment to feature additions/modifications approx. 20h/month)
- Priority Support (Highest priority response)
- Regular MTG (Participation in regular meetings)
Best for:
- Startups
- DX Promotion Companies
- New Business Development Teams

Engineering Standards
Careful attention where it's not visible.
Proactive Monitoring
It's too late to notice "after it goes down". We implement Sentry and Better Stack to build a system that detects and responds to errors before users encounter them.
Security First
Vulnerabilities are patched immediately. We constantly monitor updates for dependent libraries and, after verification, promptly apply critical security patches.
Transparency
No black boxes. To prevent "not knowing what was done," we provide monthly reports for Advisory plans and above, visualizing the site's status and completed tasks.
Workflow
Initial Audit
Current status diagnosis (free). First, we diagnose the code and configuration of the target website. We identify current versions and risks, and propose the optimal maintenance plan.
Proposal & Contract
Proposal & contract. Based on the diagnosis results, we determine the monthly fee and scope of services, then conclude the contract.
Onboarding
Environment setup. We set up repository access permissions and introduce monitoring tools (Sentry, etc.). We prepare the development environment to be ready for any response.
Regular Operation
Regular operations begin. We start monitoring and updating tasks according to the plan. For the Advisory plan, a consultation channel (e.g., Slack) will also be opened.
Monthly Report
Monthly report & regular meeting. Each month (or during regular meetings), we report on the site's operational status and maintenance performed. We discuss the next improvement actions.
Continuous Improvement
Continuous improvement. Based on monthly reports, we propose performance enhancements and new features. We continuously evolve your web assets to match business growth.
