Businesses become critically dependent on platforms for even a small fraction of their revenue (e.g., 20%). This 'monopsony power' creates a stronger lock-in than user network effects, as losing that customer base can bankrupt the business.

Contrary to the common perception of users paying off balances monthly ("transactors"), the majority—about 60%—are "revolvers" who carry debt. This group is the primary source of profit for card issuers, as they are subject to interest rates now averaging a staggering 23%.

Brands often misinterpret repeat purchases driven by discounts or points as genuine loyalty. True loyalty is an emotional connection, not a transactional one. This "entrapment" model fails to build lasting customer relationships or brand affinity.

The massive 100x return on investment for card issuers like Amex and Chase makes them insensitive to the card's cost. This dynamic protects Composecure's high margins and discourages issuers from switching to cheaper, lower-quality suppliers for their most valuable customers.

The payment card market has a stable, recurring revenue base. Of the 4 billion new cards issued annually, most are replacements for expired or lost/stolen cards, not net new accounts. This provides a durable, predictable demand floor for manufacturers like Composecure, independent of new customer growth.

Despite the rise of mobile payments, even digital-first companies like Coinbase and Robinhood are launching premium metal cards. This trend validates the physical card's enduring status as a powerful tool for acquiring high-value customers, countering the narrative of immediate digital disintermediation.

A surprisingly large portion of high credit card APRs covers operating expenses, particularly marketing. Issuers like Amex and Capital One spend billions annually on customer acquisition. This spending is passed directly to consumers, as higher marketing budgets correlate with higher chargeable rates.

Consumers are largely insensitive to the interest rates they are charged, rarely seeking out cheaper options like credit union cards. This behavioral pattern means that cutting rates is an ineffective customer acquisition strategy. Instead, issuers invest heavily in marketing, which proves more effective at attracting new borrowers.
