There is a category of Jewish philanthropist that writes checks. There is a smaller category that joins boards. And there is a much smaller category that does the harder and more dangerous thing: starts the institution from scratch. Adam Milstein has spent the last quarter-century operating in that smallest category.
His résumé makes the pattern obvious. In 2000, he and his wife Gila co-founded the Adam and Gila Milstein Family Foundation. In 2007, he was one of several co-founders of the Israeli-American Council, launched in Los Angeles alongside Israel’s then-Consul General Ehud Danoch and business leaders Naty Saidoff, Shoham Nicolet, and Shawn Evenhaim. In 2017, he and Gila co-founded the Impact Forum in Los Angeles. Three distinct institutions, each launched to fill a specific gap, each still operating, and each now structured to function without him.
The pattern is not accidental. Milstein has argued for years that the dominant Jewish philanthropic model, passive grantmaking through legacy institutions, was never going to keep pace with the threats Jewish communities are facing. In a December 2024 Jerusalem Post column, he wrote that the scale of the challenge requires donors who behave less like funders and more like founders: people willing to take operational risk, recruit leadership, set strategy, and stay involved long after the launch press release.
His real estate background informs the choice. As managing partner at Hager Pacific Properties, Milstein learned that the highest returns in any portfolio rarely come from passive positions. They come from deals where the operator is also a builder: sourcing the property, structuring the financing, recruiting the management team, and staying in the room until the asset reaches stabilization. The foundation, the IAC, and the Impact Forum were all built before they were funded. He did not write a check and hope. He built the vehicle, then routed capital through it.
The Impact Forum is the cleanest illustration. Milstein and Gila launched it in 2017 to solve a problem he had watched play out across his network for years: talented nonprofit leaders were spending 60 to 70 percent of their time fundraising instead of executing on their missions, while donors scattered resources across dozens of organizations with no coordination. The forum’s design was deliberate. Vetted nonprofits pitch their work directly to a room of philanthropists. Donors fund the work that earns their conviction. One hundred percent of donations go to the nonprofits. No overhead, no skim. The model has scaled from quarterly LA dinners to Dallas and Miami, with the most recent Miami event raising over $1.1 million in a single evening.
There is also a personal commitment to being visible about it. At the IAC’s 10th annual summit in January 2026, Milstein joined Miriam Adelson and Naty Saidoff for a panel on the discipline of public giving, reported by eJewishPhilanthropy. Adelson recounted how she came to attach her name to her donations after being told, “If I gave my name, others would donate.” Milstein’s career has reflected the same logic. The institutions he builds carry the names of their founders precisely because that visibility recruits the next generation of donors.
What distinguishes the institution-building approach is the willingness to step back. Milstein chaired the IAC from 2015 to 2019, then deliberately handed day-to-day leadership to a new generation while continuing to serve on the board. An institution that depends on its founder, he has argued, is not, in his terminology, an institution. It is a project. The test of any structure worth building is whether it functions without the person who built it.
That argument has gained traction since October 7, 2023. The Jewish institutional landscape that existed before the attack proved, in many cases, undersized for the scale of the response required. Organizations Milstein co-founded or anchor-funded years earlier found themselves absorbing demand they had been designed for. The Impact Forum’s surge in donor participation, the IAC’s mobilization of regional chapters, and the foundation’s expanded portfolio of more than 200 organizations all reflected the same dynamic. The infrastructure was already there because someone had been quietly building it.
Milstein’s public writing has returned often to a single argument: the donor who behaves like an investor and the donor who behaves like a founder produce different long-term outcomes. At 73, he is still making the case in print, but the more durable version of the argument is the three institutions he has spent twenty-five years building. Check-writing scales linearly. Institution-building compounds. The compounding, in Milstein’s career, has been the entire point.
