What comes next

Systems born under contract become the next SaaS

Leach builds systems that would normally cost hundreds of millions of yen through US-style contracted development, then turns them into SaaS other companies can use. Totsugo.com was born on a customer's shop floor.

VALUES

Treat people's time as precious.

Customers and colleagues have time they can never get back. Do not create unnecessary work or waiting. Build ways of working that can last, without relying on someone to work endlessly.

QUESTIONS

FAQ

Will I be charged automatically after the trial?

No. After the 14-day trial we ask whether you want to continue before any contract.

Not sure AI can read our documents?

Test with your real documents during the trial. If a form is hard to read, we tell you honestly on the spot.

What if this doesn't cover what we need?

Our AI Core Business Systems (FDE) service can assess the systems and integrations you need across orders, inventory and billing. Tell us how you work and where the product does not meet your needs.

LET’S TALK

Start with what’s on your mind.

Google Workspace migration, AI-ready foundations, monthly technical advisory support or AI-enabled core systems. One-off estimate reviews and programming workshops are also welcome.
