FinTech firms generally have a different business model from banks. Contrary to banks, they have little to lose. They can innovate rapidly, do not fear mistakes, let customers guide them towards better products, and focus on interfaces that maximize customer experience. An important factor that enables innovating FinTech firms to move faster is that digital technologies have huge built-in economies of scale. With digital technologies, the marginal cost of one more customer is generally fairly trivial.
