What Drives Us​

Launched in January 2024, CTOx™ is built on the process-driven frameworks and fundamentals of our sister company CMOx®, which coaches and places Fractional Chief Marketing Officers (CMOx®). CMOx® Founder Casey Stanton met Lior Weinstein when he served as a fractional CMO for Lior’s agency Fortunian. The two developed a fast friendship after discovering their mutual alignment on the value of process-driven systems that enable inevitable growth, and later decided to collaborate to create CTOx to meet the growing needs of modern businesses.

Through CTOx™, we teach CTOs and CIOs the principles of building strong, data-driven technology departments along with the sales and marketing strategies fractional CTOs need to build their businesses. It’s a collaboration built on shared values and deep respective track records of getting results.

When you hire CTOx™, you’re not just hiring a senior technologist, you’re hiring a team of vetted technology strategists and leaders. When your business hits a technology roadblock, your CTOx™ can come back to the team and strategize with us, leveraging our years of experience with hundreds of businesses to come up with a breakthrough solution.

Core to the CTOx™ approach is the CTOx Functional Marketing® Framework, which all CTOx’ers learn in our program. We take their technology expertise and hone it into a structured, repeatable, proven process that we then apply to your business. It is with this process that our CTOx’ers will make your business successful month after month, year after year.​
