Zul Digital vs Silicon Valley Bank
Zul Digital failed in 2022 due to Competition. Silicon Valley Bank failed in 2023 due to Unit Economics. Different causes, different sectors, different eras — but the same simulation outcome.

// WHY EACH FAILED
🔥 Zul Digital
Competition
Zul Digital built a digital parking meter payment app for São Paulo and other Brazilian cities. After reaching 1M users, the São Paulo city government contracted a competitor (Estapar) as the exclusive official parking app with preferential placement. Zul's volume declined rapidly as the official app captured new user adoption. Unable to compete against city-sanctioned exclusivity, Zul shut down in 2022.
// LESSON
Apps dependent on municipal contracts or city-sanctioned services are operating under a government-revocable license. Build defensibility through API integrations, loyalty, and multimodal transport before the city contract decision. Once exclusivity is granted, you have no leverage.

🔥 Silicon Valley Bank
Unit Economics
Silicon Valley Bank collapsed in March 2023 after a bank run driven by duration mismatch. SVB had invested deposits in long-duration bonds during low-rate periods. When rates rose, those bonds lost value. SVB announced a $1.8B loss on bond sales and a capital raise — triggering a $42B bank run in 24 hours. The FDIC seized SVB on March 10, 2023 — the second-largest bank failure in US history.
// LESSON
Asset-liability duration matching is not optional for banks. Investing short-term deposits in long-term bonds is a structural bet against rising rates. SVB had $80B in long-duration bonds when the Fed began the fastest rate rise cycle in 40 years.
