About

Elizabeth Orsinger

Founder & Managing Partner

Two decades on the other side of the table: as a banker to companies from start-up through late-stage growth, then as an advisor helping founders, owners and investors shape the right capital strategy.

Today she brings both together, assessing how a business runs, diagnosing what to fix or strengthen, and building a real roadmap to the next inflection point.
