Justin Stone is a seasoned venture finance and healthcare regulatory attorney who has spent his career in the trenches of fast-scaling digital health companies. Justin has served as Chief Legal Officer for three VC-backed startups that each became unicorns.
He was the first lawyer and employee #10 at MDLIVE, helping lead the company from scrappy startup to over 500 employees and a high-profile exit to Cigna Healthcare—a landmark deal in virtual care.
He then joined Thirty Madison (Keeps, Nurx, Cove), again as an early employee and General Counsel. Over his tenure, he scaled legal ops across four funding rounds, culminating in a $150M Series C at a $1B+ valuation with backing from Johnson & Johnson Innovation, Polaris, and HealthQuest.
Justin later joined Papa, a Miami-based Y Combinator startup tackling senior loneliness, as General Counsel. There, he helped lead over $200M in venture financing, including a $150M Series D led by SoftBank Vision Fund, pushing Papa’s valuation to $1.4B.
Between in-house roles, Justin founded a boutique legal and strategy advisory practice focused on early-stage healthcare tech. He’s advised 40+ digital health founders on formation, financing, and compliance, supporting over $500M in combined fundraising.
