CB Insights Venture Capital Funnel (2023)Key Lessons Learned
1. UX doesn't fix structural cost problems
Oscar built beautiful apps and easy-to-use interfaces, but the core problem — healthcare costs rising 7-10% annually — couldn't be solved by better software. Customers had great experiences while the company lost money on every claim.
2. ACA marketplaces have adverse selection risks
Oscar primarily sold through ACA exchanges, which disproportionately attract higher-risk individuals who need insurance most. This created a structurally unprofitable customer base.
3. Health insurance resists startup disruption
The health insurance industry's complexity — provider networks, drug formularies, regulatory requirements, employer relationships — creates barriers that no startup has successfully overcome.
