I build AI systems that run real businesses.

I run 7-figure brands mostly on AI with a team of two. On here I break down the builds, the tools and the systems, in plain language. When you want one built for your business, that is what my company CAZT does.

Proven on my own brands first. Never a demo, always a running system.

What I actually do

Not a guru. A builder who shows the receipts.

Most people talk about AI. I run it. Content, ads, support, reporting and operations move on their own across my brands, so the team stays tiny and the output stays high. Everything I post here is a real system you can see working.

Content

Systems that post for you

Ideas, scripts, captions and cross-posting run on a loop. I show the exact wiring.

Ads & leads

Creative and follow-up on autopilot

From competitor research to static ads to a lead that gets nurtured without me touching it.

Operations

Support, reporting, the boring stuff

The work that eats your week, handled by agents that know your brand.

The builds

Breakdowns you can copy.

Short, no-fluff walkthroughs of the tools and systems I use every day. Follow along on Instagram and LinkedIn.

The short version

From the Marechaussee to building AI operations.

I started in the military, the Royal Marechaussee. That is where I learned discipline, leadership and how to stay calm when things break.

Then I built Oergezond into a 7-figure brand, and kept building until I was running multiple brands with a team of two. The only way that works is systems. So I built AI operations that do the heavy lifting, and I kept showing the receipts.

Now I share the builds here, and my company CAZT builds them for people who want the system without figuring it all out themselves.
