The Institute for Cultural Evolution (“ICE”) is a nonprofit 501c3 think tank based in Boulder, Colorado. Our mission is to foster political and cultural evolution in America. Our main focus as a think tank is the amelioration of hyper-partisan polarization.
In furtherance of our mission, corresponding with the 2020 publication of our co-founder’s book, Developmental Politics, ICE is working to help establish a new “politics of culture.” This cultural approach to politics seeks to integrate positive values from across the political spectrum to create effective new forms of agreement.
ICE is managed by its co-founders Steve McIntosh and Carter Phipps. The think tank’s board of directors includes Whole Foods CEO John Mackey, Daily Evolver podcast host Jeff Salzman, and serial tech entrepreneur John Street.
Founded in 2013, ICE’s political position is neither left, nor right, nor centrist. We do not undertake lobbying efforts or back political candidates, and we are not associated with any political organization or party. By remaining politically independent, ICE is able to synthesize and harmonize the values and positive goals of both the left and the right. The strategies we use to widen perspectives and integrate politically opposed viewpoints are new and unique. They are based on fresh insights into how worldviews form and how human culture evolves. By clarifying the cultural roots of hyperpolarization, our analysis provides innovative solutions to this “wicked problem.”

The Presencing Institute was founded in 2006 by MIT Sloan School of Management Senior Lecturer Otto Scharmer and colleagues to create an action research platform at the intersection of science, consciousness, and profound social and organizational change. Over the past two decades, we have developed Theory U as a change framework and set of methodologies that have been used by thousands of organizations and communities worldwide to address our most pressing global challenges: climate change, food systems, inequality and exclusion, finance, healthcare and education.
We co-create innovation labs, deliver capacity building programs and conduct action research worldwide in order to support and scale profound societal innovation.

Enlivening Edge is an international community of collaborators and Partners drawn together to nourish the growing ecosystem of Next-Stage (including Teal) organizations. We are interwoven in a global vanguard of people and organizations transforming their workplaces for the benefit of all.
Inspired by Frederic Laloux’s book Reinventing Organizations, Enlivening Edge was launched in 2015. It was born through the hands, hearts, and minds of a small but passionate crew and a small seed fund provided by Future Considerations.
The original idea was to create an online publication through which people and organizations by sharing their stories could discover each other, learn about and contact each other, and begin to learn from and collaborate with one another.
Our four main expressions of our Evolutionary Purpose are EE Magazine, EE Community Conversations, EE Facebook Community, and EE’s Event Calendar.

“Circling” is a new practice and way of relating that is growing all over the world. By relating in the present moment–beyond stories, expectations and predetermined ideas about who you are–circling has the capacity to reveal your true essence and cultivate deep connections. We offer workshops, coaching & advanced trainings for seekers and transformational coaches.
The Circling method is our proprietary, multi-stage relational practice and unique transformational modality. It is a dynamic group process that is part-art-form, part-skillful facilitation and part-relational yoga. It is also a unique modality that can be practised one-on-one. Although it is based on complex ideas, participating in it can be easy and fun for people at all levels of experience. The Circling Institute is committed to making the Circling practice available to individuals who want more fulfilling relationships and a deeper experience of community… AND coaches who want to facilitate radical transformation for their clients.

Areo is an opinion and analysis digital magazine focused on current affairs — in particular: humanism, reason, science, politics, culture and human rights.
Areo, named after Milton’s speech in defence of freedom of speech, Areopagitica, publishes thoughtful essays from a variety of perspectives compatible with broadly liberal and humanist values. It places particular priority on evidence and reason-centered pieces. Our contributors are intellectually, professionally and ideologically diverse and include liberals, conservatives, socialists, libertarians, atheists and religious believers. As much as possible, Areo aims to avoid polarizing tribalistic stances and prioritizes intellectual balance, charity, honesty and rigor.
We believe in the unfettered freedom to explore, think, and challenge ideas and concepts, and we’re intent on taking part in the conversations that will shape our tomorrow.

Alter Ego is a global network of influential leaders who are pioneering psychological and cultural development in organisations and society
This isn’t a formal organization, as such, but a ‘brand’ created by Jim Rutt to provide some uniformity across a collection of discussion and collaboration entities. The name “GameB Collection” is a convenient term created by TLLP.
In particular, there is a large number of Facebook Groups. To see the most up-to-date list of these groups, visit the Facebook Page (see under Web Properties below).
Good faith conversations exploring ideas & practices that drive personal & collective development. Jason Snyder & Jared Janes host a wide variety of guests with the goal of enacting inclusive/metamodern & contemplative sensibilities.

The Long Now Foundation was established in 01996* to develop the Clock and Library projects, as well as to become the seed of a very long-term cultural institution. The Long Now Foundation hopes to provide a counterpoint to today’s accelerating culture and help make long-term thinking more common. We hope to foster responsibility in the framework of the next 10,000 years.
* The Long Now Foundation uses five-digit dates, the extra zero is to solve the deca-millennium bug which will come into effect in about 8,000 years.

Cognitive Edge was founded in 2005 with the objective of building methods, tools and capability to utilise insights from Complex Adaptive Systems theory and other scientific disciplines in social systems. This approach, known variously as Naturalising Sensemaking and Cognitive Complexity has developed three main focus areas:
The development of SenseMaker® – a software ecology which integrates decision support, research, monitoring and knowledge management
Comprehensive global education programme – a broad network of practitioners able to use the methods and tools developed by Cognitive Edge. Approximately 2,700+ Network Members now exist both within organisations and as independents
The research agenda – acknowledged by the Academy of Management with two awards for the Cynefin framework, which is at the heart of the approach

The purpose of New Discourses is to meet the need that the problem of political alienation and homelessness has created. It is especially for those who feel like they’ve been displaced from their political homes because of the movement sometimes called “Critical Social Justice” and the myriad negative effects it has had on our political environments, both on the left and on the right. It is a place where dialogue is possible and encouraged, regardless of differences in politics, aiming to be responsible with our speech and thought while not feeling fettered by restrictions of political correctness in any of its myriad manifestations. It also hopes to inspire dialogue—both new ways to discuss old topics and new conversations in their own right.
New Discourses is not interested in conservative, progressive, left, right, center, or any other particular political stances. It is, in this regard, only broadly liberal in the philosophical and ethical stance.

At Lectica, we’ve developed a sophisticated new technology that’s built around a powerful evidence-based learning model. This technology allows us to accurately diagnose people’s learning needs, then provide personalized learning recommendations that support robust learning—a kind of learning that is not only efficient and immediately useful but also helps build the skills and dispositions required for a lifetime of learning and development.
