While consumer fintech gets the hype, the most systematically important opportunities lie in building 'utility services' that connect existing institutions. These complex, non-sexy infrastructure plays—like deposit networks—enable the entire ecosystem to function more efficiently, creating a deep moat by becoming critical financial market plumbing.
America's system of nearly 10,000 banks is not a market inefficiency but a direct result of the founding fathers' aversion to centralized, oligopolistic British banks. They deliberately architected a fractured system to prevent the concentration of financial power and to better serve local business people, a principle that still shapes the economy today.
The SVB crisis wasn't a traditional bank run caused by bad loans. It was the first instance where the speed of the internet and digital fund transfers outpaced regulatory reaction, turning a manageable asset-liability mismatch into a systemic crisis. This highlights a new type of technological 'tail risk' for modern banking.
To overcome the cold start problem in a network effects business, especially in a conservative industry like finance, a powerful strategy is to create a coalition or consortium model. By giving early adopters ownership and governance rights, you align incentives, build trust, and transform would-be competitors into enthusiastic evangelists for the new network.
Silicon Valley Bank was already a member of deposit networks that could have prevented its collapse. However, 94% of its deposits remained uninsured because the bank failed to actually use the tools at its disposal. This reveals that the mere existence of a solution is worthless without proper implementation, integration, and incentives for adoption within an organization.
Building a network effects business with financial institutions represents an extreme version of the 'cold start problem.' The initial phase of getting the first ~20 participants is excruciatingly difficult due to trust deficits, regulation, and inertia. It's described as 'the worst idea of all time,' but the value captured after achieving liftoff is immense.
The concept of 'banking deserts' extends beyond underserved regions. When specialized banks like SVB disappear, entire industry verticals (like tech, agriculture, or wine) can become 'underbanked.' This creates a vacuum in specialized credit and financial services that larger, generalist banks may not fill, thus stifling innovation in specific economic sectors.
