One Medical's expansion (2007–)
Primary-care startup One Medical raised $178 million in venture funding and built physical clinics across major U.S. cities, then went public in 2020 at a $2.7 billion valuation.
Expanded to tens of clinics and signed corporate contracts with employers.
Showed that employer-centric healthcare can scale,but faced profitability pressure and was eventually acquired.
Root's model mirrors One Medical's employer-pay playbook but with functional medicine—testing whether the root-cause niche can replicate that growth.
