The Fungi Foundation is a global organization that works for the Fungi, their habitats, and the people who depend on them.

Launched in 2012, the Fungi Foundation is the first NGO dedicated to the fungi kingdom. Since its inception, it has achieved numerous milestones while dedicating itself to exploring the fungi world in view of increasing knowledge of their diversity, educating about their applications, and recommending public policy for their conservation. As part of our ongoing 3F initiative, the foundation played a key role in enabling Chile to become the first country in the world to include protection of fungi in its environmental legislation. More recently, the foundation proudly announced the Fantastic Fungi Education Curriculum, the world's first mycological set of courses designed for schools.

In short, the Fungi Foundation envisions a healthy planet in which Fungi are recognized, protected, and embraced as the interconnectors of nature; a mission that would be impossible without the essential support of our kind, engaged donors.

Spritely Institute builds, researches, and standardizes networked technology which put people and communities first.


Centralized social media is harmful to society. We are building a gatekeeper-free decentralized system. Our mission is “social media done right”, to put people in control of their own identity and build the technology that would enable a shift to collaborative and intentional security models prioritizing active consent. To accomplish this, we will build a new architecture for the internet: removing the necessity of client-server architecture, replacing it with a participatory peer-centric model.

Spritely’s technology is being released as free and open source software aiming for multiple programming language implementations and eventual open standardization. All of our work, ranging from decentralized identity, peer-to-peer user agents, decentralized social networks, encrypted and portable storage, and distributed object programming infrastructure is being built to enable a gatekeeper-free path where users and content are not tied to a specific server.

Aquatic Life Institute is a 501(c)(3) non-profit focused on reducing the suffering of aquatic animals in the global food system.

Aquatic Life Institute (ALI) was founded in 2019 to address the critical and often overlooked issue of aquatic animal welfare. Recognizing that aquatic animals are the most exploited group of animals worldwide yet remain largely unprotected, ALI set out with a mission to drive systemic change and elevate aquatic animal welfare as a priority in global food systems.

Our theory of change is rooted in the belief that by influencing key stakeholders and decision makers, advancing policies, and fostering collaboration, we can drive systemic transformation for billions of aquatic animals. 

Building on this foundation, ALI has emerged as a thought leader, advocating for tangible improvements across the seafood supply chain. By engaging with key stakeholders, including corporations, certification schemes, and policymakers, we work to ensure that aquatic animals trapped in the food system receive the attention they deserve in decision-making processes relating to sustainability and food systems. 

ALI’s work is driven by evidence-based strategies and collaboration. This approach has earned ALI widespread recognition, including a 2024 Top Charity recommendation from Animal Charity Evaluators (ACE). This endorsement solidifies ALI’s position as one of the most effective organizations in the world advancing aquatic animal welfare.

Zera Bolivia Foundation fosters indigenous-led education, enabling self-empowerment, financial independence, and social mobility.

**Zera Bolivia** is an Aymara-led foundation that hosts classes and events for kids as a response to colonial norms, championing indigenous self-determination—especially for women and girls—through transformative education grounded in emotional intelligence, critical thinking, self-awareness, and practical tools for financial independence.

We began in 2015 with a socio-emotional learning pilot at a women’s prison in La Paz, and have since grown to reach thousands of children, youth, and families across Bolivia’s nine departments. Collaborating with municipal governments, the Ministry of Education, and local communities, we co-create culturally adapted programs that honor each community’s priorities and values. Thanks to our community and donor support, we have provided training, world-class educational materials, and technology infrastructure to prisons, children’s hospitals, rural areas, schools, and grassroots groups—always centering local leadership.

From the “Qantatai” literature podcast to “Bolivian Thinkers for Everyone By Zera,” our initiatives celebrate Bolivia’s intellectual heritage and open new pathways for dialogue and growth. Participants often report stronger emotional well-being, improved academic performance, and greater economic opportunities. As we look to the future, we are developing our first “STEM for Indigenous Young Women” program in El Alto and across 20 rural provinces of La Paz, in partnership with India’s STEMED NETWORK.

When you support Zera Bolivia, you invest in locally driven, inclusive solutions that affirm the power of Indian communities to shape their own destiny. Your contribution furthers our shared vision of a Bolivia where education is a tool for self-empowerment, cultural pride, and lasting social change.

Extending and improving the lives of people with ALK+ lung cancer by raising funds for research and patient support programs.

**Our Vision**

We envision a world where ALK+ lung cancer is a chronic or even curable condition and the next person diagnosed with lung cancer does not have to live under the current stigma.

**Our Start**

\#SweatForBreath started as a grassroots fundraising campaign during Lung Cancer Awareness Month in 2023. After being diagnosed with Stage IV ALK+ lung cancer in November 2022, David Cornbrooks became keenly aware that he was benefiting from the selfless fundraising and awareness efforts of the patients before him.

[Listen to David's story here.](https://www.youtube.com/watch?v=lWcS-yN7Qxw)

The \#SweatForBreath campaign in 2023 became David, and his wife, Lisa’s, way to help the next generation ALK+ lung cancer patients.

\#SweatForBreath accelerated beyond more than just a typical fundraiser.  The initiative quickly evolved into a community of patients, caregivers, family, and friends seeking to make David and Lisa's vision a reality and the road to that vision more tolerable. People donated, sweat at the in-person cycle event, posted on social media, and helped fundraise through organizing group walks, selling art, "gifting" donations on behalf of clients, and much more.

Their success in 2023 compelled David and Lisa to officially transition the \#SweatForBreath campaign into the Sweat For Breath Foundation, operating through a fiscal sponsorship with Players Philanthropy Fund, a Maryland charitable trust recognized by IRS as a tax-exempt public charity under Section 501(c)(3) of the Internal Revenue Code (Federal Tax ID: 27-6601178).

**Our Impact**

Since 2023, over **1,450 donors** have given nearly **$400,000** to the Foundation (or its predecessor campaign). 100% of the proceeds have gone directly to The Johns Hopkins Sidney Kimmel Center in Baltimore, MD to support Dr. Vincent Lam’s ALK+ lung cancer research.

This support provided the critical funding needed to launch Dr. Lam’s clinic trial, which will evaluate the safety of a cancer peptide vaccine to prevent or delay acquired resistance in advanced ALK+ lung cancer patients currently on ALK targeted therapy. Dr. Lam’s vaccine is the **first ALK+ vaccine in the world** to be tested in a clinical trial. Dr. Lam administered the vaccine to the first patient **in clinic on May 13, 2024**!

We aim to advance the mental wellbeing of our South Asian community.

In 2021, during their freshman year of college, our founders Ravi Parekh and Aaron Pandian suffered the loss of their close friend and roommate, Farhan, in a tragic murder-suicide where he took the lives of himself and his family. 

Farhan was struggling with a variety of inadequately treated mental illnesses. However, like so many members of the South Asian-American community, his parents simply lacked the tools, resources, and education necessary for providing him the care he needed.

They recognized that, as an immigrant South Asian family, they lacked the tools, resources, and education necessary for providing Farhan the care he needed. The tragedy of Farhan and his family revealed that there are many mental health issues unique to the cultural characteristics of South Asians. Understanding that these environmental factors and structural barriers to effective care created the situation which led to this tragedy, we theorized a youth-led grass-roots advocacy and education initiative that equips South Asian youth and other interested parties with access to tools and resources to understand, process, and empower.

Grass-roots efforts are often inspired by lived experiences. Our passion and drive to bridge the gaps in mental health care for South Asian individuals stem from our lived experiences.

Knowledge is empowering, and part of understanding mental health is to both learn and express empathy for those affected who are unable to receive effective care. To learn not to fear mental illness as a sibling, parent, friend, significant other, or affected individual and employ newly acquired tools that work to connect with the resources they need. 

MHISA embodies these ideals and provides us an outlet to engage those around us with a shared goal: to enable South Asians struggling with mental illness to lead better and healthful lives.

Animal Charity Evaluators helps people help the most animals.

Do you want to help animals but find it hard to decide how? That's understandable. Trillions of animals suffer every day on farms and in the wild. The problem is vast and complex, but people around the world are making a difference.

Animal Charity Evaluators (ACE) is a 501(c)(3) nonprofit registered in the United States dedicated to finding and promoting the most effective ways to help animals. We do this by evaluating and recommending high-impact charities, awarding strategic grants to promising projects, and raising critical funds for the animal advocacy movement. Our ultimate goal is to educate and empower individuals and organizations to make a significant and lasting positive impact on the lives of neglected animals who are often forgotten. ACE envisions a future in which no individual is given less than full moral consideration on the basis of any morally irrelevant feature of their identity, including species membership.

ACE has a unique and influential role within the effective animal advocacy movement. Our global team is composed of experienced professionals in animal advocacy, effective altruism, and research methodology. To date, we have rigorously evaluated 85 charities that work to end factory farming and create meaningful change for farmed and wild animals, and recommended 38 high-impact organizations as effective giving opportunities. Through our strategic grantmaking, we have distributed nearly $20 million to our Recommended Charities and promising advocacy projects around the globe. Since ACE began tracking this metric in 2014, we estimate that we’ve helped to influence at least $81 million within the animal advocacy movement. Over the years, we have built strong partnerships with organizations and researchers, amplifying our collective efforts to improve the lives of as many animals as possible. 

Join us! Together, we can build a future that's kind to *all* species.

Trains and empowers educators/leaders to create racially equitable, safe, and empowering educational spaces for all youth.

The Center for Racial Justice in Education (CRJE) works to construct a new reality within our country's public school system; a world where all young people learn and thrive in equitable and affirming educational spaces. CRJE’s work with districts, schools, organizations, and community members result in empowered educators and leaders who are better equipped to build educational institutions that foster equitable outcomes, and ensure that all students have safe, inclusive, and culturally responsive spaces to learn.

 Since 2012 alone CRJE has trained over 17,000 educators/leaders, reached over 167,000 youth, and worked with over 400 educational partners in 17 states. Our work consists of intensive leadership and professional development trainings, longer-term, in-depth coaching and consultation, community-driven climate assessments, and youth-adult partnerships, all customized to meet the unique needs of each educational partner. In the long-term, through collective practice for educational equity at the institutional level, and through mutually accountable partnerships and coalition building at the community level, we aim to build an education system and spaces where all youth feel safe, and have access to a high-quality education. In this system, we will see:

- Students who are emotionally, physically and academically thriving. 
- Educators and leaders who have an ongoing, consistent practice of building educational communities grounded in equity. 
- Caregivers who are empowered to actively engage in community building.
- Public policy that has shifted to reflect racial equity and justice in education.
