Sean Chiasson

I work at the intersection of finance, operations, and strategy, building the systems that turn financial discipline into clarity, collaboration, and trust. As Director of Finance & Operations at Toniic—and its senior-most finance leader—I own finance, operations, compliance, and co-own HR for a global community of private asset owners moving capital toward the world's most underfunded, high-impact opportunities. Over six years I've grown from an Accounting Associate into this role, building the controls, systems, and reporting that support a $4M operating budget and a distributed team across 7 countries. Most recently, I've led the organization through 5 consecutive clean audits and am co-creating Toniic's new business strategy. I serve on the Board of Directors of the American Alpine Club and the Finance Committee of The Climate Trust—roles grounded in fiduciary duty, strategy, governance, and the stewardship of capital. MBA and MS in Finance, Portland State University. I'm focused on helping purpose-driven organizations build a financial foundation equal to their ambition.
