Muso

What Muso does

Muso is a 501(c)(3) global health nonprofit, founded in 2005 and headquartered in San Francisco, that designs, validates, and scales the "Rapid Care" model for delivering proactive community health care in low-resource settings. The model rests on three operational pillars: paid, professional Community Health Workers (proCHWs) who conduct door-to-door home visits; 360° Supervision supported by a performance management dashboard; and the removal of out-of-pocket fees at upgraded primary care centers. The underlying technology stack combines Medic Mobile's Community Health Toolkit (CHT) mobile application for CHW supervision and data management with KOBO Collect for survey and monitoring work, both of which are integrated into national government health information systems in Mali and Côte d'Ivoire.

Muso does not generate revenue from patients. Instead, it operates a sales-led, grant-funded business model, securing institutional funding from foundations, bilateral donors (USAID), multilateral organizations (WHO, UNICEF, the Global Fund, Gavi), and individual donations. The organization's customers are effectively two national Ministries of Health (Mali and Côte d'Ivoire), which it serves through technical assistance contracts, embedded specialist placements, and co-developed national policy reform. Reach metrics include 25,510,785 proCHW home visits, 600,000+ people served since 2008, 8,200 CHWs under enhanced supervision in Côte d'Ivoire, and child mortality reductions from 154 to 7 per 1,000 live births in partner Malian communities.

Operationally, Muso runs a multi-country footprint with offices in Bamako, Abidjan, and San Francisco, and a team of 501-1,000 employees and partner CHWs. The organization is currently navigating a leadership transition: co-founder and CEO Dr. Ari Johnson announced in March 2025 that he will step down after twenty years, with a new CEO search initiated while he remains engaged on policy and partnerships.
