About Us

Coexius is a software consulting and development firm dedicated to helping businesses modernize legacy systems, integrate AI, and build practical, scalable technology solutions. Founded and led by Michael Payne, a veteran developer with over 25 years of experience, Coexius blends deep technical expertise with real-world business insight to deliver custom solutions that drive results.

We specialize in transforming outdated applications into modern platforms, enabling companies to reduce costs, improve efficiency, and stay competitive. Our services include software architecture, custom application development, cloud migration, and AI readiness assessments, with a strong focus on aligning technology with business strategy.

At Coexius, we pride ourselves on being a trusted partner—not just a vendor. Whether working with small businesses, startups, or established enterprises, we take the time to understand each client’s goals and challenges. Our approach is collaborative, practical, and tailored to meet real business needs—not just deliverables.

While based in the U.S. and serving clients nationally, Coexius values local business connections and community growth. We’re always eager to support fellow Chamber members through partnerships, shared learning, and technology leadership.

Let’s build what’s next—together.
