Hi, I'm Cal.

I help owner-led local businesses run with less of the owner in the middle of everything.

Cal Hamilton, founder of Wide Margin Systems

My story

I started in industrial design, then spent 15+ years in product and operations: software for energy, video and construction, including Projektr, a construction project management company I founded. I've also worked offshore as a mud logger, so I know what a long shift looks like.

At a boutique home builder in East Dallas, I led sales and marketing and helped grow it into a $100M business with a team of 5. We didn't do it with more people. We did it with clear processes, the right tools and a lot of automation.

That's the thread through all of it. I've been the one buying software to run a business, and the one building the software other businesses run on. I know where the time goes, and I know what's worth fixing.

Why Wide Margin Systems

I live north of Dallas, surrounded by people who own local businesses. Almost every one of them is working too many hours on things a good system could handle, and paying for tools that don't talk to each other.

Wide Margin Systems is the partner I'd want in their shoes: one person who looks at the whole business, from the first lead to the books, and fixes it in the right order.
