Steven Marquez
Co-Founder & Chief Operating Officer
Steven Marquez co-founded MindRefined with over two decades of experience as a technology strategist, security researcher, and operational leader. As COO, he brings a rare blend of deep technical expertise and proven executive strategy, responsible for building the company's operational framework, managing strategic risk, and scaling its innovative data solutions.
His career has been shaped by securing and architecting some of the nation's most complex environments, including an organization with an annual budget exceeding $7 billion, a scale comparable to that of a Fortune 500 enterprise. His initiatives have been pivotal in driving large-scale secure cloud migrations, deploying enterprise-wide SIEM solutions, and collaborating with legal departments to author data-sharing agreements and manage third-party risk experience that directly informs MindRefined's corporate governance and operational integrity.
Steven's leadership is built on a foundation of deep, hands-on research. His independent investigations have uncovered critical vulnerabilities across the technology spectrum, from billion-dollar SaaS platforms and enterprise IoT to the Industrial Control Systems (ICS) and SCADA environments that manage critical infrastructure. This unique ability to deconstruct complex systems and investigate insider threats has made him a trusted liaison for federal law enforcement, including the FBI and Secret Service, in complex criminal investigations.
A passionate technologist at the intersection of AI and data analysis, Steven's practical expertise in machine learning is the technical heart of MindRefined's vision. He has successfully developed custom solutions using Large Language Models (LLMs) to innovate security analysis and automate complex operations, positioning the company at the forefront of the next generation of intelligent solutions.
