Describes two social ventures' experience of collaborating with each other through a replication project funded by Lemelson and the Schwab Foundations. Each venture served different purposes: IDEAAS installed and operated alternative solar energy equipment in locations without access to Brazil's electricity grid, and Saude & Alegria educated populations in the Brazilian Amazon jungle on matters of health, environment conservation, and self-sustainable wealth generation. The replication project entailed having Saude & Alegria help IDEAAS expand its service offering from the south of Brazil into the Amazon region. After describing the organizations, the replication project, and its results, highlights the core success factors that possibly led to the project's ultimate outcomes, allowing students to take positions and debate the critical success factors enabling the successful collaboration between social ventures.
