[San Francisco, CA – November 2, 2023] Third Plateau and Hirsch Philanthropy Partners announced today that the two firms have merged to expand and enhance their services across the social impact and philanthropic advising sectors.

Together, Third Plateau and Hirsch Philanthropy Partners aim to tackle pressing societal issues, foster innovative solutions, and reimagine how to achieve a brighter, more equitable, and uplifting world. Amid growing polarization, which hinders the pursuit of effective solutions, this merger places a strong emphasis on fostering collaboration. It unites two industry-leading firms with expert, cross-cutting approaches and a shared mission to work alongside nonprofit, philanthropic, and public sectors in addressing the complex challenges of today and tomorrow.

In a joint letter published today, the firms’ founders expressed the authentic roots of the merger as a partnership to meet the urgency of our time. They emphasized their shared commitment to working in trust with communities to achieve a more just, equitable, and democratic society.

The merger consolidates the firms’ top-tier social impact and philanthropic advising services, including foundation management, strategic planning, research, program design, measurement and evaluation, leadership development, and more.

Third Plateau is also home to the Democracy Funders Network and Patriots and Pragmatists, two cross-ideological consortiums that fuel some of today’s most vital democracy partnerships.

Hirsch Philanthropy Partners was founded by Susan Mayer Hirsch in 1999 and is one of the first and best-regarded philanthropic advising firms in the U.S. The firm works with individuals, families, and foundations to create and implement visionary giving strategies. Since its founding, Hirsch has directed $1.6B to organizations, leaders, and public sector agencies boldly solving our most pressing challenges. The firm’s hallmark is building effective public-private partnerships to achieve transformative structural change.

“Joining the strength of our firms is momentous. Third Plateau and Hirsch Philanthropy Partners are driven to expand and deepen our collective impact as part of the broader social change ecosystem,” said Daniel Kaufman. “Hirsch Philanthropy Partners’ signature approach to philanthropic advising is undoubtedly best-in-class. As we join together with Susan and our new colleagues, we’re prepared to fuel even more impactful societal change at a time when it is needed the most.”

“For decades, our team has embodied a deep commitment to working in partnership and trust with communities,” said Susan Hirsch. “That commitment is shared by the Third Plateau team and makes this merger a special fit to accelerate the work ahead. We have long viewed Third Plateau as the gold standard of social impact consulting for driving sustainable change while changing people’s lives now. This merger will open new possibilities for the health, vibrancy, and prosperity of communities, no matter how great the challenges may be.”
