Who are Open Briefing 

People and communities around the world have the solutions to social injustice, authoritarianism, and the climate crisis. But repressive governments, corrupt corporations, and armed groups use violence and oppression to try and silence them.

By building resistance and resilience among those challenging unaccountable power, Open Briefing supports a shared vision for a world where communities and ecosystems can thrive.

Our dual approach allows us to work at every level of civil society, from the grassroots to the global. As a mission-driven nonprofit, we join forces with grassroots activists, community groups, and social movements at risk. Working together, we strengthen their physical security, digital resilience, and collective wellbeing.

As a social impact consultancy, we provide professional support and advisory services to global nonprofits and foundations seeking to bolster their risk management, data protection, and staff care.

"To describe Open Briefing as a caring partner would be an understatement. They have consistently been at the forefront, providing invaluable support whenever we have faced security threats. Open Briefing has stood by us, offering bespoke services that have enabled us to carry out our mandate with confidence and timeliness. Their support has given us the peace of mind necessary to operate fearlessly and effectively." 

Phyllis Omido, executive director of the Center for Justice Governance & Environmental Action, Kenya and Winner of the Goldman Environmental Prize 

Protecting people at risk 

The need for our work has never been greater. At least 300 human rights defenders and 91 journalists were killed in 2024. Many others were arrested, kidnapped, or forced into hiding. 

Last year, we worked with those around the world fighting for human rights and social justice, protecting the environment and defending their communities, exposing corruption and reporting the truth, and advocating for women’s rights and reproductive justice. We supported organisations and activists at risk in 100 countries across every inhabited continent, underscoring the global scale of the challenges we face.  

The number of requests for our support increased by 20% on the previous year to 575 in 2024. This represents 11 new cases every week. In response, our international team provided over 6,000 hours of direct support, a 32% increase on 2023. Roughly a third of the cases that we worked on were with individual defenders or informal collectives and 33% of all cases involved those defending their land and rivers or demanding climate action. We also trained 1,014 defenders in 112 workshops.

“I came out of my work with Open Briefing stronger. I know that because of the work I do, the security risks I face won’t go away, but I’m not as fearful. I used to doubt and question myself, but now I know what to do. I know how to manage the risks we face.” 

Director, women-led human rights organisation, West Africa 

Our efforts delivered measurable impact. We reduced perceived risk by 15% and achieved a remarkable 25% improvement in individuals' stated capacity to manage those risks - significantly enhancing the safety and resilience of those we served. An inspiring 84% approval rating from clients and grassroots partners underscores the meaningful difference we made, reaffirming the effectiveness and importance of our work in this complex and challenging field. 

I fled into exile after being arrested and torture by police and people close to me were murdered. Open Briefing helped me when no other organisation could. I had lost hope, but their support saved my life.” Investigative journalist, Rwanda

The wider impact of our work was captured in an external impact evaluation commissioned by a donor last year, which concluded that: “The different issues around which the activists had sought support from Open Briefing were profound, serious, and challenging. The scale of the risks is such that it would not be possible for them to operate without this kind of support. The nature of the support that Open Briefing has provided is therefore highly important, and has allowed activism to continue in contexts where it might not otherwise be able to.” 

Becoming fundable and findable 

With demand for our support up by 66% in the past two years, we need to ensure that we have the funding and resources to direct our support wherever we are needed most. 

We are proud to have built long standing partnerships with a small community of foundations who have been crucial to our success so far. But we can’t meet the current surge in demand for our support without growing this community. We need more people to know about the threats facing grassroots activists, human rights defenders, and indigenous communities around the world. We need more people to understand why physical security, digital resilience, and collective wellbeing is vital in helping them continue their work. We need more people to know about Open Briefing. 

“Open Briefing's expertise has been revolutionary for our organization. They have helped us develop the tools we need to better safeguard our team and respond to safety and security risks. All of this was done in a way designed for our organisation and considering our own limitations. Doing this kind of security work should be inherent to any organisation like ours that works in vulnerable communities and sensitive areas; however, it's not always within reach.” Dylan Terrell, Founder and Executive Director, Caminos de Agua, Mexico 

In May 2026, Open Briefing will come to the end of our current strategy cycle and will be looking ahead to where we need to scale our work and strengthen our impact. We need to make sure that we have the funding and resources to protect even more people, effect systemic change, and ensure the eyes of the world are on the perpetrators of attacks and reprisals. 

This means we need to be findable and fundable. To date, Open Briefing has largely operated behind the scenes, building a solid reputation as a trusted ally and critical friend to grassroots activists, movements, and foundations across the globe. 

Going forward, we must build our profile and widen our support base. We need to pursue innovative and creative approaches to communicating who we are and the human stories behind our work. We need to reach new audiences in order to engage and influence a wider network of donors, allies, and philanthropists across the globe. And crucially, we need to translate this work into new donations and unrestricted funding.

Key to this will be the formation of our first Development Board. We are looking to achieve a step change in our fundraising, help us build our audience, develop exciting communications and support us in ways we haven’t even thought of yet! 

Could this be you? 

• Are you passionate about bringing your skills, expertise, and networks to a dynamic global non-profit? 
• Are you excited about collaborating with us to help protect people and communities on the frontlines of the fight against social injustice, authoritarianism, and the climate crisis? 
• Do you have bold ideas for how Open Briefing could be more findable and fundable? Can you help us translate your ideas and our ambitions into creative, impactful strategies that could lead to new funding and resources for our security and wellbeing work? 
• Are you disinterested in ‘talking-shop Boards? Are you looking for an opportunity to use your skills, creativity, voice and connections in a way that will directly power our fundraising and communications work - making introductions to your network, brainstorming around key challenges, and executing dynamic profile-raising events and campaigns?  

We are looking for 3 - 5 people to join a dynamic, passionate and action-orientated Development Board. Previous experience as a Trustee or on a non-profit Board is not required.  We are particularly interested in people with experience from the following industries: 

• Communications, design, and media
• Technology
• Venture capital
• Strategy consultancy
• Fundraising, philanthropy, events, and giving circles.

We are asking potential members to commit to an initial one-year term and to be available to meet online on a monthly basis, with engagement between as necessary. 

If this sounds like you, please tell us what makes you excited about the role and upload your CV. If you have any questions, please reach out to us.

We would love to talk!
