Ehsan's Analysis
The Rule of 40 is poorly suited to FinTech because financial services have structurally different margin profiles. A payments company with 40% growth and 15% margin (Rule of 40: 55) looks healthier than a neobank with 60% growth and -30% margin (Rule of 40: 30), but the neobank may have better unit economics at scale because interchange margins improve with volume while payments margins stay flat. The FinTech-adapted Rule of 40 should use "unit-level margin" (margin on an incremental customer) instead of company-level margin. By unit-level margin, many high-growth FinTech companies that look unprofitable are actually generating positive contribution per customer — they are just investing in compliance, technology, and growth. Nubank was Rule of 40 negative for years but had positive unit economics from year 2 of each cohort. The market eventually recognized this and rewarded it with a $40B+ valuation.
