Thirty Madison dominates specialized telehealth with a $280M Series D funding round, operating a multi-brand platform that includes Nurx, Keeps, Facet, and Evens. The company serves over 1 million patients across women’s health, hair loss, skincare, and GI care, achieving an 85% patient satisfaction rate—outperforming the general telehealth average of 67%. This condition-specific model drives superior outcomes and loyalty, supported by concrete data: each brand addresses a distinct medical need, reducing fragmentation and improving care continuity. By focusing on niche areas, Thirty Madison outperforms #10 Calibrate in breadth of service, offering four specialized verticals compared to Calibrate’s single metabolic platform. The $280M in Series D funding also underscores strong investor confidence, enabling further expansion into new conditions and geographies.

Calibrate leads the GLP-1 metabolic health space with over $200M raised, integrating prescription weight loss medications with a one-year behavioral coaching program. Its outcome-based model demonstrates a 15% or greater body weight reduction at 12 months among 20,000+ members, which is 50% higher than the typical weight loss program average. The platform’s employer and health plan partnerships extend coverage to 5 million potential members, making it a scalable solution for population health. In a direct comparison, Calibrate’s 15% weight loss efficacy outperforms #9 Thirty Madison’s satisfaction metric, as it provides a quantifiable, clinically significant result tied to member adherence. This data-driven approach, combined with a robust coverage network, positions Calibrate as a benchmark for metabolic health innovation, offering a concrete measurement of success that general telehealth cannot match.
