Reut Group

Gidi Grinstein established the Reut Group in Tel Aviv in 2004, structuring it as a non-profit leadership, strategy, and impact organization. The group trains young leaders while deploying its research and strategy methodology — rooted in the work of the Praxis Institute's Zvi Lanir — to overhaul stale governmental and communal mindsets. Its American Friends arm channels philanthropic support from the United States. Reut operates across three policy lines: national security, Israeli-Jewish relations (peoplehood), and socio-economic development. Its methodology identifies blind spots where leadership perception has diverged from on-the-ground reality, then designs new models to close those gaps. It has shaped strategy for dozens of organizations, including Hillel International and the Tel Aviv Municipality. Global program Tikkun Olam Makers (TOM) — co-founded by Grinstein — uses open-source design to build affordable assistive technology for people with disabilities, drawing support from philanthropist Alexander Mashkevich for TOM Kazakhstan. Geographic work covers Israel, the United States, and Jewish communities worldwide. Reut's scale is defined by its network rather than its balance sheet. It operates from Tel Aviv, runs Impact Labs Tel Aviv, and maintains a professional network that places alumni into key public positions across Israel and the Jewish world. Leadership and alumni are linked to the Wexner Foundation's Israel Fellowship and the Zero Project. In December 2022 the group was hiring for analyst roles, signaling continued operational expansion. It convenes strategic summits — a November 2021 New York gathering and a 2022 US-Israel emergency conference in Tel Aviv both aimed at recalibrating diaspora ties. Reut's structural differentiator is its R&D-like posture inside the policy and communal ecosystem. It functions less like a traditional endowment and more like an applied-thought lab: it frames problems using a proprietary blind-spot methodology, architects strategy for external clients, and spins out operating initiatives — TOM being the most tangible — that turn analysis into permanent infrastructure.

Frequently asked questions

Who runs investment decisions at Reut Group?

Reut Group functions as a non-profit think tank and policy-strategy organization rather than an allocator of capital. President Gidi Grinstein drives strategic direction, and CEO Abed Assli leads day-to-day operations. The organization's decisions center on research priorities, partnership selection, and initiative design — not portfolio allocation.

How does Reut Group source its strategic engagements?

Reut originates advisory and strategy work through relationships with Israeli government ministries, municipalities like Tel Aviv, and global Jewish organizations such as Hillel International. It also publishes forward-looking reports, such as those done in collaboration with the Ruderman Family Foundation, that attract institutional clients seeking reframing analysis of blind spots.

Is Reut Group structured as a single family office or a foundation?

It is a non-profit institute, not a family office. Formed by Gidi Grinstein in 2004 and supported by American Friends of the Reut Institute, it operates as a leadership and impact organization with an R&D-like methodology, while Tikkun Olam Makers functions as a separate global initiative co-founded by Grinstein.

Does Reut Group manage an endowment or make direct investments?

No. Reut does not disclose an endowment, does not invest in companies or funds, and does not deploy capital as an allocator. It is funded by philanthropic contributions and partnerships, channeling resources toward policy research, strategic consulting, and operating initiatives like TOM.

Which policy areas does Reut Group explicitly prioritize?

Reut Group works across three explicit tracks: national security (including Israel-US relations), Israeli-Jewish peoplehood and diaspora diplomacy, and socio-economic development. Its 2022 activities spanned a US-Israel strategic summit to a peoplehood-mapping project.

How is Reut Group related to Tikkun Olam Makers (TOM)?

TOM is a global initiative co-founded by Reut's Gidi Grinstein that creates open-source assistive technology for underserved communities. While TOM operates with its own structure, it shares origins with Reut's model of turning reframed strategic insights into scalable, long-running programs — including a Kazakhstan chapter supported by philanthropist Alexander Mashkevich.

What is Reut Group’s known governance and alumni footprint?

Leadership includes Gidi Grinstein as Founder-President and Abed Assli as CEO. Past CEOs Netaly Ophir-Flint and Eran Shayshon remain part of the broader network. Alumni hold key public positions, and staff members are often Wexner Israel Fellows or Zero Project Scaling Fellows, embedding Reut's methodology across Israeli public life and the Jewish world.
