[About me]

Explore The Ecosystem

I'm John King. Founder, engineer and operator. I build the technology that makes businesses work and the systems that make them grow, and I share what I learn along the way.

Technology is a means. Never the end.

01

The problem comes first.

Before choosing a technology, understand who needs help, what they're trying to do and where the current approach falls short.

02

Useful over sophisticated.

Sometimes the answer is AI. Sometimes it's simpler software or a clearer process.

03

What I learn carries forward.

Every company and every product sharpens the questions I ask in the next one.

An engineer’s curiosityA founder's responsibility.

My background is in software engineering, architecture and technical leadership. Building businesses widened the questions I have to answer: who needs this, how do we reach them and what does it take to make it work over time?

Today I build and operate companies and software products, stay close to the technical work and share what I learn.
