My Mission
My name is John Carter. I am a former nuclear submarine Captain and served for over 30 years in the U.S. submarine force in high-demand roles around the globe. After my service, I spent almost a decade in the energy sector further broadening and sharpening my business, technical, and executive leadership skills.
I founded CoreX to help SMB executives thrive as elite Captains in their companies.
I built CoreX to help deep-technology companies turn technical brilliance into scalable business performance.
My mission is to equip founders, CEOs, and executive teams with the strategy, leadership discipline, and operating rigor required to grow without losing control of execution, culture, or direction.
I serve funded startups and growth-stage firms in energy, nuclear, aerospace, advanced manufacturing, engineering, and AI that need stronger alignment, accountability, and organizational readiness as complexity increases.
CoreX exists to close the gap between innovation and execution. Through executive advisory, leadership development, and operational hardening, we help technical leaders build resilient companies that move faster, adapt better, and create lasting value in demanding markets.
You don't have to go it alone!
Five & Fly Testimonial
I initially doubted whether a business coach was worth the investment. However, after connecting with John and sharing some Navy banter (Beat Navy!), I knew I could trust him. I am very glad I did.
During our discovery call, John asked insightful questions about my business’s current standing, our struggles, and our future goals. Rather than simply telling me what to do, he sought my perspective to help build a path forward, much like a coach reviewing film to develop a winning game plan.
We have worked together for the past quarter, and the value he has provided through his network and strategic guidance has been exceptional. Working with John feels like being back on the gridiron; he recognizes his clients' potential and drive and provides the necessary insight to grow and win. We are now building a solid process that is gaining significant momentum.

Credtent, Inc Testimonial
John is a sharp strategic partner and a top-tier connector that got us a lawyer to help us in a bind. He's also provided us quality connections to discuss funding, and, most importantly, offered excellent insight into how we communicate about Credtent’s unique full-cycle content for AI licensing platform. I highly recommend working with John.

Peak Analytical Labs Testimonial
John has been an invaluable strategic thought partner as I’ve worked to launch my startup.

Beyond his insight, John has connected me with meaningful business partners who have been instrumental in moving my business forward.

Juume AI Testimonial
John has been an incredible advisor and consultant for Juume. He’s highly engaged, attentive, and always proactive in getting our name out there. John doesn’t sit back and wait—he’s constantly making introductions and putting Juume in front of the right people. His willingness to reach out, connect, and advocate for us has made a real impact.
On top of that, he’s just very likable and easy to trust, which goes a long way. As a fellow Navy nuke, he brings that same level of discipline, accountability, and high standards to everything he does.
