For more than a decade, One Earth Future ( https://oneearthfuture.org/ ) has worked to solve complex problems at the root of armed conflict. Through its unique culture of iterative learning and improvement, OEF designs, tests, and partners to scale programs that help communities see problems in new ways and solve them collectively. With headquarters in Colorado and offices around the world, OEF operates as a portfolio of peacebuilding ventures, each with its own director, strategy, and budget. What holds them together is a common purpose: to provide an impartial platform for diverse stakeholders to form adaptive problem-solving networks for peace. At the foundation level, OEF provides the financial, strategic, and operational support needed to iteratively develop solutions to complex problems that could not have been designed in advance.
