Legal clarity for bold ideas.

Backed by Experience.
I’ve been on both sides of the table—leading high-growth fintechs and serving as outside counsel—and I’ve seen just how costly early legal missteps can be. Knowledgable, proactive legal support isn’t just nice to have; it’s a critical piece of building a lasting venture. Early mistakes in legal and regulatory strategy can create hurdles that slow or even derail a startup’s momentum. And yet, finding a legal partner who truly grasps both the rapid-fire demands of launching a fintech and the complexities of regulation can be surprisingly difficult.
That’s why I decided to focus my energy on helping founders from day one. Drawing on my experience across banking infrastructure, digital assets, payments, and global compliance, I offer tailored legal services that fuel innovation rather than hinder it. Your time is best spent creating, scaling, and securing funding—not getting entangled in administrative pitfalls. My goal is to be the outside general counsel I wish I’d had when I was in the thick of building fintech ventures.
Whether you’re shaping the next big solution in financial technology or looking for clarity in an increasingly complex regulatory environment, I’m here to help you build on a solid legal foundation. Let me handle the fine print, so you can focus on taking your bold ideas to market.
