ABOUT CALLIE AHERN
I am a strategic Revenue Leader and GTM Executive with over 15 years of experience building and scaling high-performing organizations within the fintech and SaaS sectors. Currently leading Enterprise Supplier Growth at BILL, I specialize in architecting scalable GTM infrastructure and outbound playbooks designed to engage CFO and Treasury personas at scale. Throughout my career, I have navigated critical growth inflection points, notably managing a $40M+ enterprise portfolio at Klarna while overseeing strategic global integrations for brands such as Google Store and Apple.At my core, I am an entrepreneur at heart; when I’m not driving complex enterprise deals, I am building Twofold Wellness, a science-backed consumer brand I co-founded to simplify self-care for women. Whether I’m navigating a board-level presentation or keeping up with my fierce toddler, I thrive on the challenge of building something impactful from the ground up.
