CB Insights Venture Capital Funnel (2023)Key Lessons Learned
1. Mobile telematics data quality is insufficient
Smartphone sensors can detect hard braking and speeding, but can't measure the dozens of factors (road type, weather awareness, vehicle condition) that actually predict accident risk.
2. $400 CAC for $800 annual premium is suicidal
Root spent heavily on digital advertising to acquire each customer, but car insurance policies have high churn and low margins. At $400 CAC, each customer was unprofitable for 2+ years.
3. Growth-stage investors don't understand insurance
DST, Tiger, and Dragoneer invested based on tech metrics (growth rate, app downloads) not insurance metrics (combined ratio, loss ratio, reserve adequacy).
