Who I am

Veteran. Strategist. Solo investor backing bold founders building for equity, sustainability, and the future of work.

Funding Requirements

I invest in early-stage founders building at the intersection of sustainability, wellness, and equity—especially those historically overlooked by traditional capital. I look for mission-driven businesses with a clear path to profitability and a bold vision for systemic change. I'm particularly excited by circular economy models, consumer health, AI.

Value add

I know what it’s like to hustle with purpose. I support founders who are solving real problems for overlooked communities. With a background in strategy, sustainability, and inclusive leadership, I bring a mix of tactical insight, emotional intelligence, and a deep belief in doing good and well.
