• Invests primarily at the seed / early stage in companies based in or connected to the Southwest U.S., consistent with the Desert Angels' regional mandate.
• Sector-broad rather than sector-specialized — his own capital has gone into consumer products, medical instrumentation/devices, software, and healthcare research and product development.
• Emphasizes rigorous process: he has publicly stated he "enjoys screening, due diligence, and process re-engineering," with a stated desire to "help the next generation of investors spot investable companies."
• Values investment readiness — through Startup EcoSystem he works to make early-stage companies more prepared for investor scrutiny, signaling he responds well to founders who arrive with clear operations, financials, and a defensible plan.
• Brings an operator's lens (CEO/CFO/CTO background) — favors teams that demonstrate financial discipline, sound unit economics, and credible go-to-market and M&A/exit thinking.
