About

I am the Founder and Managing Partner of Síol Venture Capital, a pre-seed fund built on a simple thesis: regulation is not a risk—it is a source of alpha. We invest in startups operating in heavily regulated markets before regulatory clarity, when opportunity is mispriced and competition is limited. While others wait for policy to settle, we help founders navigate and shape it—creating durable advantages that are difficult to replicate. At Síol, I invest with a focus on where policy creates asymmetric opportunity: >I invest 2–5 years before regulatory clarity, when risk is mispriced and competition is limited >I treat legislative and regulatory developments as predictive signals for market inflection points >I underwrite regulatory risk directly, unlocking opportunities others cannot price >I help founders turn regulatory complexity into a durable competitive advantage Before Síol, I spent 25+ years in government relations, advising companies across Congress, federal agencies, and 40+ states on how policy decisions shape market outcomes. That experience became the foundation for my investment approach: treating regulatory change as a predictive signal—and investing ahead of it.
