Switchboard.
I co-founded Switchboard, a social enterprise that created mobile phone networks for health workers in Ghana, Liberia and Tanzania.
We created “in” networks whereby any health worker (from doctors to rural health workers) could communicate free-of-charge to one another. We also built directory services by which these health workers could contact one another to seek advice and refer patients. We were funded through a mix of telecom profit-sharing and several large donors (Google.org among them). Switchboard was eventually acquired by a large nonprofit working with health workers across Africa.
