Documented cause
Sure Inc., a San Francisco embedded insurance API platform founded by Wayne Slavin, raised $100M across multiple rounds including a $100M Series C in 2022 led by Winter Capital. Despite powering embedded insurance for major brands including Uber and United Airlines, the company could not generate sustainable unit economics. Revenue reportedly reached $30M ARR but losses ran at $50M+ annually. By early 2024 the company conducted mass layoffs and wound down operations.
Lesson
“Infrastructure-layer insurtech requires carrier-level scale to survive; API fees alone rarely cover actuarial risk exposure.”
