Root Causes
Key Lessons Learned
1. Insurance AI hype vs actuarial reality
Lemonade claimed AI would make better underwriting decisions than traditional actuaries. In practice, their AI approved too many high-risk policies because it optimized for growth, not risk selection.
2. Easy onboarding attracts adverse selection
Lemonade's frictionless sign-up (90-second policy) attracted customers who were rejected by or too lazy for traditional insurers — exactly the high-risk pool you don't want.
3. SoftBank valuations create zombie companies
At $10.6B peak valuation, Lemonade needed to become a top-10 US insurer to justify the price. Now trading at $1B, it's too expensive to acquire but too unprofitable to sustain.
