What we build開発するSaaS

Software products, for every model.

We work from the first product concept, or join an existing product that needs engineering support.

B2B SaaS

Software a business sells to other businesses, with organisations, seats and roles.

Consumer SaaS

Subscription products for individual users, built for sign-up and retention.

Internal platforms

Software that replaces spreadsheets and manual processes inside a company.

AI SaaS

Products where AI is the core of the experience, not a feature bolted on.

Marketplaces

Platforms connecting customers and providers, with listings, bookings and payouts.

Vertical SaaS

Specialised software for one industry, built around how that industry works.
Platform featuresSaaSの基盤機能

Everything your SaaS needs, already understood.

The features customers expect from any paid product. We have built them before, so your budget goes on what makes your product different.

Authentication

Email, Google and social sign-in, password reset and sessions.

Subscriptions

Free, monthly, annual and usage-based plans.

Billing

Stripe and other payment integrations, invoices and receipts.

Multi-tenancy

Separate organisations, users and data per customer.

Permissions

Admin, staff, customer and custom roles.

Dashboards

Analytics, management screens and customer portals.

AI

Agents, assistants and intelligent workflows.

APIs

Connect your product to external systems and let customers integrate.

Notifications

Email, push and automated notifications.

Built for business
システム設計

Your SaaS needs more than a good interface.

What customers see is the top layer. Underneath is the engineering that makes a product reliable enough to charge for, and we build all of it.

Product designプロダクトデザイン

Build something people actually want to use.

Design is where a SaaS wins or loses its trial users. We design the flows before writing code, test them, and only then build.

DiscoveryUser flowsWireframesUI/UXPrototypeFeedbackDevelopment

  • User experience

    Clear paths to the value your product delivers.

  • Conversion

    Sign-up and upgrade flows that don't lose people.

  • Onboarding

    First-run setup that gets a new account working.

  • Information architecture

    Navigation that scales as features grow.

  • Responsive design

    Works on desktop, tablet and phone.

  • Accessibility

    Usable by everyone, following WCAG.

Pricing and monetization収益モデル

We build the business model into the product.

Plans, limits and billing are part of the architecture from day one, so changing your pricing later is a setting, not a rebuild.

Project pricing料金の目安

Starting prices, fixed before we start.

Every project is different. These are starting points for a defined scope. Once we understand your requirements, you receive a detailed proposal and one fixed price before development begins, so there are no surprise invoices halfway through.

Cloud infrastructure, payment processing and AI and API usage are billed separately.

Prices exclude consumption tax.

SaaS MVP

A first release with accounts, subscriptions, billing and an admin dashboard, ready for real users.

From
¥500,000

Production SaaS

Established products, larger feature sets, or infrastructure and uptime requirements.

Custom quote
SaaS CareSaaSの保守・運用

Production SaaS has users, payments and uptime to protect, so SaaS Care is built for that rather than for a small website. Cloud infrastructure, payment processing, AI and API usage and other third-party services are billed separately.

A SaaS MVP starts from ¥500,000, excluding tax, and production SaaS is a custom quote. Every project gets a written scope and one fixed price before work starts, and we help cut the MVP to the smallest version that proves the idea. After launch, SaaS Care starts from ¥10,000 a month.
