The Team Behind Your Strategy
The Strategic Architect
Archie Stamp brings more than 14 years of enterprise IT leadership to Sentinel — spanning digital transformation, security governance, and technology strategy across complex, multi-site organizations. His focus is aligning technology investment with business growth, operational resilience, and long-term performance.
With deep expertise in cloud strategy, infrastructure modernization, and enterprise risk management — plus hands-on experience across SOX, SOC 2, ISO 27001, NIST-CSF, HIPAA, FISMA, CMMC, and PCI — Archie delivers Fortune 500 caliber leadership to the businesses that need it most.
Where Strategy Meets Execution
Steven Duncan is a seasoned IT executive with nearly two decades of experience modernizing enterprise infrastructure across complex, multi-site environments. As Founder, Chief Innovation Officer, and Chief AI Officer, he delivers strategic technology leadership to organizations that need executive-level guidance without the overhead of a full-time hire.
What sets Steven apart is his ability to operate at the intersection of strategy and execution — equally comfortable advising C-suite executives on technology roadmaps as he is leading hands-on infrastructure deployments.
A forward-thinking technologist, Steven is pioneering the integration of Agentic AI into IT operations — bringing emerging technology into practical application with controlled scope, measurable efficiency gains, and uncompromising governance.
Security-First Leadership
Thomas McGehee brings over 25 years of experience at the intersection of technology transformation, cybersecurity, and operational management. A 13-year Army veteran and former DoD contractor, Thomas combines a mission-first mentality with elite business acumen from MIT and MBA education.
He is recognized for translating complex corporate visions into secure, scalable realities — leading diverse teams to deliver innovation and sustainable growth in high-stakes environments.
Thomas is an active member of InfraGard and ISC2 and brings deep security expertise across CMMC, SOC, SOX, HIPAA, FISMA, and NIST compliance frameworks.
Why We Built Sentinel
The Problem
Businesses with 5 to 100 employees are stuck in a dangerous gap. They're too complex for basic IT support but can't justify a $250K+ full-time CIO. Critical technology decisions get made without strategic leadership — and the cost of getting them wrong compounds fast.
Our Belief
Every growing business deserves the caliber of IT leadership that Fortune 500 companies take for granted. Technology should accelerate your business, not slow it down.
Our Difference
We bring 14+ years of enterprise executive experience — cloud strategy, compliance, digital transformation, AI — and deliver it at a scale and price built for SMBs. We're vendor-neutral, invested in your outcomes, and we speak your language.
