The improbable story of how Visa became the most profitable company in the world per employee. A cooperative of competing banks that built a payment network processing $14 trillion annually with only 30,000 employees.
Canon
•
Hock proposed that the BankAmericard system should become an independent, decentralized network owned by no single bank. Every executive told him it was impossible. His courage to fight institutional resistance created the modern payment network.
•
Visa doesn't process payments — it sets the rules that banks follow when processing payments. By designing the environment (interchange rules, settlement protocols, brand standards), Visa shapes the behavior of 14,000 member banks without giving a single direct order.
Highlights
•
Network effects in payments are the strongest in any industry — once established, they are nearly impossible to disrupt
Visa's network effect is circular and self-reinforcing: more cardholders attract more merchants, which attracts more cardholders. At $14T in annual volume, the network is essentially unassailable.
