We are a foundation built on tradition and committed to transformation.

In 1990, Max Feffer and his father, Leon, created the Arymax Foundation, with the objective of organizing the philanthropic activities of the family, which already supported several projects as well as social and cultural organizations within and outside the Jewish community.

The name was created from the combination of Ary, from the Hebrew “aryeh”, which means “lion”, a reference to the patriarch Leon, and the name of his son, Max Feffer (1926-2001), indicating solidarity as a family value to be passed on from generation to generation.

Leon Feffer’s entrepreneurial spirit, combined with his bond with the Jewish community and always accompanied by the strength and sensitivity of his companion, Antonietta, have also impacted the identity of the Arymax Foundation throughout its history.

With a path based on strong values that span generations and persist to the present day, Arymax Foundation has, over the years, expanded its scope of activities to encompass all Brazilian society and, from 2010, began to dedicate its expertise and capital to support social innovation and training young leaders.


In 2015, a long and rigorous process of reflection and study began, in search of a new stance based on the use of evidence, meeting a demand from the Board, composed of members of the third and fourth generations of the family. The study involved Brazilian and international experts and culminated, in 2019, in the choice of a new cause: Productive Inclusion.

Keeping the legacy of its founders Leon and Max Feffer alive, Arymax Foundation continues to support projects and institutions in the Jewish community.

We believe that no problem can be solved alone. For this reason, we strengthen and value partnerships with other organizations, sharing our path with all those who share the dream of building a firer world.

A strategic plan is developed with the aim of improving the investment focus of the Arymax Foundation in the Jewish Community.


The start of the Arymax Scholarship Program, in partnership with Unibes, focusing on the Jewish community. The period from 2006 to 2009 is also marked by support for the purchase of land and the subsequent construction of a new headquarters for the Shalom Community.


After consulting with a focus on structure, the first superintendent is hired with exclusive dedication to the Foundation, initiating a new era of Arymax.


Through consulting proposed by Synergos, new areas are chosen for philanthropic investment: Education and Youth Leadership. The Arymax Youth Talent Program is also created which, between 2010 and 2018, encouraged 95 young people with an entrepreneurial spirit to transform Brazilian society.


The Arymax Community Activism Challenge, inspired by the global challenge “Design for Change”, invites high school youth from public and private schools in São Paulo to create projects that solve social problems. From 2012 to 2017, more than 300 young people were impacted, and the authors of the selected projects received mentoring, practical tools and a cash prize for the development of their solutions.


The Beth-El Congregation, with a focus on more plural Judaism, has its new headquarters inaugurated, with the support of Arymax. Colégio Bialik is transferred to Clube Hebraica, changing its name to Escola Alef, with support from Arymax in the construction of its new headquarters. From 2012 to 2016, the Foundation also participated in the creation and launch of the Scholarship Fund Program, which unites several scholarship donation programs in schools in the Jewish Community.


Participation of the fourth generation of the family starts in Arymax.


The Project Competition is launched, which has had 4 annual events. More than 30 projects were selected that focused on direct social impact in a community, in areas such as education, professional training and sustainability. Young people between 20 and 35 years old received support to make their ideas viable, in addition to seed investment and mentoring for a year.


The Center for Leadership and Innovation (CLI) is launched, co-founded by the Arymax and Insper Foundation, with the goal of creating new political, business and intellectual leaders in Brazil and the world.


Support in the merger of Escola Alef with Colégio I. L. Peretz, giving rise to Escola Alef Peretz.


Using the Effective Altruism approach, the consultancies Founders Pledge and PAF (Philanthropy Advisory Fellowship) work with Arymax to identify 2 to 3 areas / causes relevant to the development of Brazil. After an analysis of 19 areas, the cause of Productive Inclusion was chosen as the focus for investment.


Evidence gathering for the definition of new strategies of the Arymax Foundation for the next decade, which culminated in the definition of 3 investment areas: Jewish Community, Productive Inclusion and Strengthening of the Institutional Field. In partnership with the Pranay Fund, the publication “Productive Inclusion in Brazil - Evidence to boost job and income opportunities” was launched.

In the same year, the Jewish Museum of São Paulo was inaugurated, with support from Arymax.

Launch of the new study "The Future of Productive Inclusion in Brazil: from social emergency to post-pandemic paths".

To make the right choices, we choose to look at what really makes a difference.

We have defined some premises for selecting the initiatives we support, always based on evidence and on what society really needs. Whatever the initiative, we maintain constant monitoring and evaluation of our actions to learn, improve and increase potential.

Arymax supports:

Initiatives in which we recognize an effective potential for positive impact.

Meaningful solutions that allow us to generate knowledge and subsidize the social field with good evidence.

Initiatives that can thrive, scale and reach large populations.

Networks, alliances and coalitions in which we can insert ourselves, fostering relationships based on cooperation and synergy in the ecosystem.

Initiatives led by civil society actors that have accumulated experience and knowledge that already work in the social field.

Organizations whose practices prioritize responsibility and commitment to the truth, which express their principles clearly and act accordingly.

Innovative and inspiring solutions for current and future challenges in the programs in which we operate.

Organizations that are structured and have planning in order to guarantee their longevity and relevance.

Initiatives that can act as an example for others.

Organizations that, due to their recognized excellence, are able to influence, mobilize and bring together other relevant and influential partners and referrals.

Our Team

Proximity, respect and collaboration. Between us and with everyone who helps us produce.
