Simple software

businesses.
We build focused software products for founders, creators, and small teams running businesses online.
What we do
Independent software products for online businesses.
Satosushi is a software company. We build, launch, and maintain a suite of independent SaaS products — each one designed to handle a specific task that online businesses deal with regularly.
Our products are separate, subscription-based tools. You choose what you need. Nothing is bundled, and nothing is required.

Most of our products can be set up in under ten minutes. No sales call, no onboarding checklist — just sign up and start using it.
Predictable pricing
Flat monthly or annual plans with no usage surprises. Every plan includes a clear description of what is and isn't included.
Actively maintained
We run and maintain every product we publish. Bug fixes ship fast. When something changes, we communicate it clearly.
