Strategic Finance - GTM

In 1976, the British statistician George Box wrote that “all models are wrong, but some are useful,” which remains a fundamental principle for anyone attempting to model the complexities of reality. Just as a map would need to be the size of a city to capture every last detail, a financial model that captures every nuance of a business would rival that business in scale. The challenge of a model builder is thus to find the balance between detail and brevity that allows a model to represent the most important dynamics that drive a business, while making the right simplifying assumptions to ensure the model is a useful tool for decision making. At Mercury, we’re revolutionizing banking* for the modern age and building the finance stack that empowers startups to thrive. As we expand our horizons with new business lines and reach more customers, we need financial reporting, models, and infrastructure that evolve at the pace of our business.
