About

From one cleaner to a system other owners run on.

Corex was not designed in an agency. It was built inside a cleaning company, under real pressure, by the two people who had to make it work.

The founders

    How it started

    Natural Cleaning Experts began in Austin with one cleaner and no marketing budget. Every job came from things we built ourselves: a brand people trusted at first glance, a website that answered every question, a Google profile that kept ranking, and a phone that was always answered.

    Building the machine

    As the calendar filled, the work moved from cleaning to systems: how a lead becomes a booked job, how a team is scheduled and paid, how quality is checked, how a second market opens without the founders being there. Boca Raton, Florida came next, and the system held.

    Why Corex exists

    Other owners started asking how we did it. First we answered one at a time, then we packaged it: Corex — the operating platform for service companies, and Corex Marketing — the brand, website, search and sales work that fills it. Corex Operational System LLC was registered in March 2026 in Round Rock, Texas.

    Where we are

    More than twenty cleaning business owners across the US work with us, from Texas and Florida to Ohio, Illinois and Oregon. Every one of them got the same thing we built for ourselves: a system, not a package.

What we believe

Operator mindset

We run a cleaning company ourselves. Every recommendation has been tested on our own calendar and payroll first.

No packages

A plan is built around your stage. What does not create impact now is not on the invoice.

Real numbers

Approximate is fine, made up is not. We show what we can stand behind.

Speed with care

A site in weeks, not months — and still checked on a phone in the field before it goes live.
