Momentum is a training institute and movement incubator.


Momentum is dedicated to movement building.


We are committed to teaching and learning the craft of popular movements fighting for justice. We give grassroots organizers the tools to build massive, decentralized social movements that aim to shift the terrain under policymakers’ feet.

We live in a time of severe inequality, racial disparity, and concentrated wealth in the United States. We need transformational change, and we believe it won’t come from within the political system. We need big movements, and we need leaders with the skills to shift public opinion and organize people at scale. 

Momentum is committed to supporting these leaders with an organizing model rooted in international civil resistance, with tools that will win profound structural and cultural changes.

POC Momentum Training

Early 2020
Boston, MA

This Momentum training is exclusively for people of color (POC), and is an intensive 4-day training on movement building for activists and organizers leading efforts to transform our political climate. Our curriculum is designed to give organizers the tools to build progressive popular social movements to win on the most pressing justice issues of our time, drawing on lessons and skills from contemporary and historic social movements.

Communities of color in the United States have been targeted by government and citizens alike for centuries, and also have immense wisdom from generations of struggle. POC Momentum is a space for organizers of color to learn together, to invest in each other’s leadership, and to support one another in the long fight for the affirmation of everyone’s inherent humanity and worth.

Cycle of Momentum

We teach organizers how to activate the public and change the political weather by using the cycle of momentum, focusing on: 

Popular movements need to force the public to take notice of the issue and take a stance. Escalating strategic nonviolent action drives a wedge into the public’s moral conscience by asking: which side are you on?

We know that political power flows from the cooperation of the people, and we base our training principles in a social view of power. When people are activated, and refuse to cooperate with injustice in massive numbers, they win.


In order to get to scale, movements need to decentralize to have the capacity to absorb new members during critical moments of public attention. In order to decentralize without collapsing into chaos, movements must “frontload” their story, strategy, and structure.


Here’s what past participants are saying about Momentum:

The Momentum trainings not only share valuable information to help our movements get more strategic and clear in the different roles and approaches that are needed, but also builds strong and collaborative relationships across movements to help us become much sharper and more united.
— Kate Werning, Organizing Director, CTZNWELL
Many have tried and failed to get organizations to be like the movements in the streets. And many have tried and failed to build movements that can move power. Momentum is a place where you can learn to do both.
— Yonah Lieberman, IfNotNow National Coordinator
Momentum has given me language for understanding organizing and strategy as a craft — a set of skills to be honed and practiced in community. It has helped me see myself as a young leader walking in the footsteps of generations upon generations of organizers and freedom fighters who I can look to and learn from. And it has enabled me to shift from seeing my experiences in social movements not as isolated incidents but as parts of long historical and political cycles that can be seen in many social movements. Momentum is the single most valuable training you can go to to advance your understanding of how social movements build power to win.
— Sara Blazevic, Sunrise Movement Co-Founder
We need to get serious about the shared language and model of how we effectively do our work. This is an opportunity to enter that conversation, learn a lot, and fold into a powerful community trying to change not only the world, but how we go about building a new one.
— Kandace Montgomery, Black Lives Matter Minneapolis
Momentum has completely changed the way I look at the work we do. It has made me see that there are different ways of organizing and building power with and for the community.
— Diego Ramirez Vargas, Homestead Equal Rights for All, Cosecha
Momentum has completely changed the way that I understand organizing. It has completely transformed the way that I understand power. It has given me a renewed hope in transformational change instead of just focusing on incremental change. Momentum has pushed me and my staff to rethink our organizing strategies, and has helped us to think a lot more deeply about our strategies and dream a lot bigger around our impact.
— Dan Gelbtuch, #IHaveAFuture Movement, Youth Jobs Coalition Co-Director
