Affirm's profitable growth without late fees or revolving interest refutes the banking industry assumption that such fees are necessary for lending profitability.

Max Levchin explains that long-term installment loans require genuine machine learning underwriting because shortcuts like FICO scores or social graph signals break down at multi-year loan horizons.
“We are the only company in the industry really there's plenty of competitors who are trying and some degree of success but mostly not really who will go into these longerterm loans and by longer I don't mean mortgage for you know 15 plus years but like three and a half years is a fairly long period of time relative to the average bailator which is like 6 weeks and to do that you have to underwrite like you can't shortcut the I'll just look at your FICO score or I'll just sort of you know I'll look at your Facebook friends like none of that works you actually have to do a real very sophisticated degree of machine learning work.”Max Levchin · 3 Sep 2026
