“Inverting: What Are Traditional Lenders Structurally Incentivized to Do That Borrowers Dislike??”
It is 2012, traditional credit cards and consumer lenders are built to earn attractive returns from revolving balances, penalty fees, and consumer indiscipline. Their economics improve when the borrower underestimates his future behavior. This creates a fundamental misalignment: the lender benefits when the customer makes mistakes.
Innovator Dilemma: “Show me the incentive, and I will show you the outcome”
Challenging the conventional wisdom. Instead of charging the customer interest for a lack of discipline, I will run a business model that asks the merchant to subsidize the financing in exchange for higher conversion, a bigger basket size, and incremental sales. The customer sees a transparent, fixed payment plan; the merchant pays only when a transaction closes. That is a far more aligned system, and one Charlie Munger would likely appreciate.
Opportunity through Ulysses Contract. The opportunity lies in large discretionary purchases where the customer wants certainty, hates compounding interest, and might otherwise abandon the purchase. In those moments, a zero-interest installment plan is not merely credit. It is a Ulysses Contract—a commitment device. By asking borrowers to commit to a pre-agreed repayment schedule upfront, the business removes the psychological barrier to spending, much like a weight-loss program that requires an upfront commitment to enforce future discipline.
If this works, the economics are simple in concept:
“Merchant fee + servicing revenue + interest income + other revenue sources - funding cost - credit losses - operating cost - any hedging expense”
“Invert, Always Invert: How to Guarantee Failure”
If I wanted to destroy this business from the start, I would do the following.
Chasing growth by approving weak credits.
Fund fixed merchant economics with overly expensive, concentrated or unstable capital.
Take a simplistic view that cost of capital stays cheap or at the historical mean forever.
Market the product as a generic BNPL button with no trust advantage, no underwriting edge, and no distribution edge.
Fund it solely with my own balance sheet only.
Therefore, I must design the business around a few non-negotiables.
Underwriting must occur at the point of sale and in real time, using more proprietary data than a blunt legacy FICO score.
Repayment must be frictionless, ideally automatic, because reducing effort improves actual behavior.
Loan duration should be short, so capital recycles quickly and exposure to rate shocks stays manageable.
Build multiple, resilient funding sources.
Elementary Worldly Wisdom To Drive Adoption.
I need to trigger a network effect quickly before competitors realize the potential of the business model and reduce it to pure price competition.
Neural Imprinting. I will market the product as a tool for disciplined purchasing, not as a debt trap. By building brand associations around transparency, zero late-fee gotchas, and clean fixed-payment schedules, I imprint a positive financial habit in the user's mind.
Ulysses Contract— By asking borrowers to commit to a pre-agreed repayment schedule upfront, I turn financing into a self-binding device rather than an open-ended debt trap.
Complex Systems & Natural Selection. In a complex system, the environment eventually adapts to minority preferences if those preferences are economically important. Just as a restaurant may shift its menu to accommodate a small group of allergy-sensitive customers, merchants will adapt if enough shoppers seek interest-free pay-over-time options. Once those customers begin favoring merchants that offer this payment method, non-adopting merchants will gradually be forced to follow.
Principal of least effort. Making sign-up, approval, and repayment nearly automatic.
Lindy Effect. If Affirm can survive and fund loans during difficult times, merchants will increasingly prefer it as a stable and trustworthy partner. The longer it survives, the more credible it becomes.
Signaling Effect. Because merchants prefer to keep similar checkout options limited, top-tier merchants will choose the most recognized and trusted BNPL brand. That leaves weaker, price-cutting competitors starved of distribution.
Defending the Moats & Solving The Problem Of Generational Transfer
In early stage, I will defend my moat by integrating small advantages that add up to a whole greater than the sum of its parts: better real-time underwriting, stronger consumer trust, premium merchant distribution, lower funding costs at scale.
In the later stage, I will increase stickiness and expand the value proposition through product expansion. With a strong merchant and borrower base, I can extend from integrated checkout into a card-based product that follows the customer everywhere, allowing participation in off-network transactions and adding interchange and possibly advertising economics. I can also offer longer-duration, interest-bearing loans, provided I preserve clarity, fixed terms, and no adversarial tricks. Expansion to family deposit accounts should also solve the problem of generational transfer.
“Thinking From the New Player’s Perspective”
I acknowledge that a new entrant will always try to steal market share by offering lower prices. Therefore, I must keep my pricing competitive while expanding the value proposition for both merchants and borrowers before the market fully commoditizes.
Walking Through The High Level Maths.
In 2012, U.S. Millennials represent roughly 80 million people, and Generation Z will add another 65 million over the next decade, making the 140 million digital-native cohort a reasonable long-term target market.
Assume the average young adult spends $15,000 annually and roughly 50% ($7,500) of that is discretionary, the immediate Total Addressable Market (TAM) of spending is roughly $1T in 2012.
Phase 1. I rely entirely on a 0% APR model where the merchant subsidizes the loan. My total revenue yield is purely the merchant network fee, which sits around a 3% to 4% take rate on GMV. Traditional banks will likely leave me alone during this phase because adopting a 0% model would cannibalize their highly profitable revolving credit businesses.
Phase 2. As competition increases, new entrants will undercut merchant fees to compete for market share, pushing my yield down over time. Therefore, once I have locked in user trust, I need to expand into interest-bearing loans for higher yield.
By blending merchant fees with consumer-paid interest, my total top-line revenue yield can expand to roughly 8% of GMV as my net margin is squeezed between my structurally higher cost of capital and the natural ceiling of traditional banking rates.
Phase 3 - Ultimate End Game. Once I build a strong ecosystem of merchants and consumers, I move upmarket by launching a proprietary shopping marketplace and introducing my own deposit accounts. This expansion allows me to capture high-margin advertising fees and close the money loop, so users increasingly live on my ledger while merchants are integrated directly into my network. By combining the high intent of a search engine, the margins of an ad network, and the closed-loop economics of a bank, I build a self-contained and highly profitable ecosystem.
Assuming inflation doubles discretionary spending to $15,000 per user, the total digital-native spending pool expands to $2T.
Assume 50% of the population dislike traditional banks, my addressable GMV is roughly $1T.
With intense competition and a commoditized market, I might only capture a 20% market share of the GMV, giving me roughly $200B in processed volume.
If Phase 3 succeeds, a blended 10% top-line revenue yield would generate $20 Billion in total annual revenue.
If the business then achieves a 20% net margin after tax because marketplace economics and closed-loop funding materially improve profitability, that would produce roughly $4 billion in annual earnings.
Applying a 15x earnings multiple implies a value of roughly $60 billion by 2032.
