Plexus Institute’s Journey Ends, But Navigating Complexity Never Ends For more than two decades, Plexus Institute has been a leading advocate for the application of complexity science to organizational and social challenges. Our archives contain a wealth of materials—including research, case studies, recorded dialogues, and thought leadership—that have played a pivotal role in shaping the field of applied complexity. However, as a completely volunteer-led organization, Plexus Institute is no longer in a position to sustain ongoing operations or effectively maintain and share this important body of work. As a result, Plexus Institute will discontinue all direct communications, programs, and organizational activities as of April 1, 2025. A Call for Partnership: Preserving the Plexus Archives With this transition, we are seeking a partner to help preserve and manage the Plexus archives, ensuring their continued accessibility and impact. These materials represent decades of applied complexity research and practice, and we believe their value can extend far beyond Plexus Institute. We are looking for an organization, institute, or initiative that aligns with Plexus’ mission and can serve as a steward for these archives, curating, sharing, and making them available to complexity practitioners, researchers, and leaders. If you or your organization are interested in exploring potential models of stewardship, curation, and engagement, we welcome the opportunity to discuss this collaboration. What This Means for the Plexus Community As of April 1, 2025, Plexus Institute will:Discontinue all direct mailings, newsletters, and email updates.Cease all formal programs and initiatives.Maintain limited access to archives on the current Plexus website for as long as possible How to Stay Connected Join the Plexus Institute 2025 LinkedIn Group – This group serves as a community-driven space for those who have engaged with Plexus Institute over the years—practitioners, researchers, leaders, and changemakers—and who want to continue to explore complexity science, emergent change, and systemic transformation.  What’s Next After Plexus? Stay Updated Your participation and support have been integral to the evolving patterns of Plexus Institute’s journey. As we reach this inflection point, we invite those interested in stewarding the future of the Plexus archives to contact Denise Easton. Just as complex systems adapt and transform, the ideas and practices of applied complexity will continue to emerge, evolve, and influence the future.

Our Enduring Mission Fostering the health of organizations, communities, individuals and our natural environment by helping people recognize, understand and use concepts emerging from the science of complexity.”
