By avoiding wholesale, which consumes margin, Every Other Thursday can price its high-quality goods below competitors. This direct model provides flexibility to absorb higher production costs and prioritize a better value proposition for the end customer.

Unlike D2C brands paying for ads, Affirm is paid a fee by merchants to acquire customers. This negative CAC is possible because merchants want a third party to handle the complexities of the financial relationship (billing, collections), making Affirm a partner, not a vendor.

Affirm discovered its true value when a merchant marketed its installment plans *before* checkout, boosting conversion by 30%. This shifted the product from a simple payment option to a powerful top-of-funnel marketing and sales tool for merchants.

Max Levchin's firsthand struggle with hidden fees and the long-term impact of a credit card mistake—even after his PayPal success—was the direct catalyst for founding Affirm. The goal was to build a transparent lending model born from personal pain.

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.

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.

Affirm's CEO argues the core flaw of credit cards is not high APRs, but a business model that profits from consumer mistakes. Lenders are incentivized by compounding interest and late fees, meaning they benefit when customers take longer to pay and stumble.

Levchin identified that millennials' hatred of banks wasn't a fleeting trend but a deep distrust formed during their teenage years watching their families suffer in the 2008 crisis. This generational trauma created a ready-made audience primed for a transparent financial alternative like Affirm, as they would try anything but traditional banks.

Max Levchin argues credit has "devolved" into a model that profits from late fees and complexity. Affirm's founding principle and core value is "no fine print," ensuring radical transparency with simple interest and zero late fees to rebuild consumer trust.
