Evaluating only Metromile’s profile at its peak — without knowing the outcome — the model ranked Unit economics as the #1 likely cause. That’s exactly how it died.

Documented cause
Metromile pioneered per-mile auto insurance, targeting low-mileage urban drivers with telematics-driven pricing. The model attracted exactly the wrong customer: low-mileage drivers are lower revenue, and adverse selection meant the remaining customers filed disproportionately expensive claims. Metromile went public via SPAC merger with INSU Acquisition Corp II in January 2021 at a 1.3B USD valuation. The stock fell over 90% within 18 months. Lemonade acquired Metromile for approximately 145M USD in an all-stock deal in April 2022 — a 90% discount to the SPAC valuation.
Alternative account: Metromile built a pay-per-mile car insurance model using OBD-II dongles to track mileage — a genuine innovation for low-mileage urban drivers. The company raised ~$300M and merged with a SPAC in 2021 at a $1.3B valuation. But Metromile's customer base (low-mileage drivers) proved to be adversely selected: the drivers who care most about per-mile pricing are those who drive very little — and low-mileage drivers have disproportionate accident rates. Combined loss ratios exceeded 100% repeatedly. Lemonade acquired Metromile in January 2022 for $500M in Lemonade stock, but Lemonade's own stock had fallen significantly — the effective deal value was well under $200M.
Lesson
“Adverse selection is not a software problem. Telematics data can price risk perfectly; it cannot change who buys the product.
Alternative account: In insurance, pricing innovation requires actuarial validation before growth capital. Metromile raised $300M+ while its loss ratios were already showing adverse selection. The SPAC amplified investor confidence in a business model that hadn't solved its core underwriting problem.”
