Alex Rampell on why the best companies have hostages, not customers

The enduring dominance of the Visa and MasterCard duopoly stems from a "chaotic" network effect that creates an impregnable intermediary layer between banks and merchants. While these networks function as transaction processors, they operate as sophisticated product designers that align incentives across the entire financial ecosystem. In the era of AI, enterprise software is undergoing a fundamental shift where labor-intensive processes are being transmuted into automated, payment-driven workflows. Success in this landscape requires navigating the principal-agent problem, as software must appeal to the specific incentives of individual employees rather than just the abstract goals of the organization. By focusing on opportunities to the right of the supply-demand equilibrium, entrepreneurs can identify vertical markets—such as automating administrative tasks in niche industries—that were previously economically unviable due to high customer acquisition costs.
