Operator mindset
We run a cleaning company ourselves. Every recommendation has been tested on our own calendar and payroll first.
About
Corex grew from hands-on experience running a cleaning company. Today, Zalina and Viktoriia bring together experienced specialists in marketing, design, development and sales to help other owners grow their businesses.
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.
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.
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.
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.

A plan is built around your stage. What does not create impact now is not on the invoice.
Approximate is fine, made up is not. We show what we can stand behind.
A site in weeks, not months — and still checked on a phone in the field before it goes live.

Before moving to the US, Zalina worked in wedding planning and photography. Today, as co-founder and CEO, she leads Corex’s development and marketing strategy alongside the experienced Corex Marketing team.

Operations, sales and client success. Runs the cleaning company day to day and turns what works there into what Corex clients get.
