Sarah Biller, Co-founder of FinTech Sandbox, joins host Rory Holland to explore the deep intersection of data, human values, and market stability. Drawing from her roots as an 11th-generation West Virginian, Sarah reflects on how early lessons in independence and community shaped her approach to modern finance.

The conversation touches on her early work using machine learning to detect credit risk, drawing an analogy to oceanic buoy sensors that alert coastal communities before a crisis hits. Sarah breaks down why high-quality data remains the ultimate bottleneck for startup innovation and how FinTech Sandbox helps entrepreneurs bridge that gap.

Together, they unpack the risks of relying on AI speed over deep understanding, the urgent need to treat financial literacy as a public health imperative, and the power of authentic storytelling to cut through digital noise.
