FounderOS

Systems, not guesswork.

FounderOS is my field guide for founders who want to build smarter, automate growth, and scale securely without adding chaos or headcount.

I believe freedom comes from designing systems, not from doing more work.
This is where I share how I build, automate, and secure businesses that run themselves.

Why FounderOS

After years leading engineering and security teams in Japan’s fintech scene, I learned that the real path to growth isn’t through more effort, it’s through better design.
Systems make outcomes predictable, automation multiplies impact, and security keeps it sustainable.

FounderOS is where I combine those ideas into a repeatable framework for independent founders and lean teams.

What You’ll Learn

Each issue explores how to:

• Turn repeatable tasks into automated workflows

• Use AI to eliminate low-value, high-effort work

• Build security directly into your systems, not bolt it on later

• Design lean, scalable growth processes for SaaS and service businesses

• Create leverage so your business runs, even when you’re offline
