About John

I'm John Sambrook. I started Common Sense Systems in Kirkland in 1996, and I've spent the years since building software and systems where getting it wrong is expensive, including medical device software and hospital operations.

Along the way I trained in the Theory of Constraints, a practical way of finding the one thing that limits a business and fixing that first. It's why I don't start with the technology. I start with what's holding you back.

These days I run my own business on AI assistants: my morning brief, my email and calendar, my follow-ups, my BNI records. I know where they shine and where they quietly go wrong. Now I set them up for other owners and keep them running.

I'm an active BNI member. If you're on the Eastside, I'm happy to meet for coffee.
