Offering a desirable physical gift—a "MIFK"—with an annual subscription renewal can be a powerful tactic to combat churn. The appeal of a limited-time physical item can persuade even disengaged users to re-subscribe, as seen with the Endel app offering a bag.

Instead of viewing them as separate efforts, businesses should link customer retention and acquisition. By unifying data to better re-engage existing customers via owned channels like email and SMS, brands increase lifetime value. This, in turn, reduces the long-term pressure and cost associated with acquiring entirely new customers.

Instead of paid marketing, Nubank scaled to over 120 million users with a customer acquisition cost of just a few dollars. This was achieved organically through word-of-mouth, fueled by a superior value proposition (no fees, better service) that solved a clear and painful consumer problem, enabled by a 20x more efficient cost structure.

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.

By engineering your model so that the gross profit from a new customer in their first 30 days exceeds your acquisition cost (CAC), you can fund marketing on an interest-free credit card. The customer's own payment repays the debt before interest accrues, creating a self-funding growth loop.

Advanced retailers are moving beyond treating retail media as an ad channel for short-term sales. They integrate it with loyalty programs to deliver personalized value, which strengthens long-term customer relationships and retention, making it a strategic lever for growth.

Merchants pay BNPL providers like Affirm more than credit card processors for three key benefits: converting hesitant buyers ('incremental sales'), ensuring high approval rates so the option is useful, and protecting their brand from association with lenders who charge punitive fees.

To serve its largest customers, Square's open platform is crucial. It allows enterprises to integrate their preferred third-party tools with Square's core services. This flexibility prevents churn by allowing customers to customize their tech stack instead of being locked into a closed ecosystem.
