Transformative Philanthropy

How can philanthropy partner with communities and organizations to create a profoundly better world?

We guide and manage family, individual, and foundation philanthropy to maximize impact and create lasting results.

At the heart of philanthropy lies possibility. Because philanthropists and funders can do more than fix what’s broken. They can build what’s possible. That’s why Third Plateau’s philanthropic experts are passionate about supporting individuals, families, and foundations to create lasting social good.

To date, we’ve advised and managed over $2 billion in philanthropic investments through meaningful and effective giving across issues such as democracy, faith, education, health, social justice, the environment, arts and culture, and community development.

As a full-service philanthropy partner, we help clarify your vision for a better world, design custom strategies and systems, and work hand in hand with clients and communities. Drawing on decades of experience, our experts can guide every stage of the philanthropic journey — from early vision-setting to managing complex portfolios and building multi-generational legacies.

Services for Philanthropy

Foundations, families, and funder networks count on us for custom partnerships and holistic services that can stand alone or be combined to meet each client’s needs.

Philanthropic Advising

Purposeful giving is deeply personal. Our experienced advisors partner with individuals, families, foundations, and donor-advised funds to clarify values, define priorities, and develop giving strategies. Drawing on trusted relationships and expertise, we guide giving portfolios that translate your unique vision into long-term impact.

Program Design

From concept to execution, successful programs require hands-on management and visionary design. Our philanthropy experts design, launch, and manage philanthropic programs and initiatives — from grant programs and public-private partnerships to community-based initiatives.

Foundation Finance & Administration

Third Plateau is a premier private foundation management firm, functioning as your dedicated team. Our full-service team delivers comprehensive accounting and financial management, regulatory compliance, and day-to-day administration.

Grants Management

Effective grantmaking depends on rigor, trust, and the robust systems that make it possible. Our expert grantmaking team manages the full grant lifecycle — from research, proposal intake, and due diligence to grantee communication, compliance, and reporting.

Board Management & Governance

Good governance strengthens philanthropic impact. We deliver end-to-end board support for trustees, including compliance, meeting facilitation, agenda setting, governance design, policy development, and capacity-building to ensure effective oversight and shared accountability.

Impact Evaluation

Understanding impact drives strategic clarity and long-term effectiveness. Our in-house research team designs evaluations that inform strategy, strengthen accountability, and support adaptive action across portfolios, programs, and collaboratives — whether for internal learning or publication.

Spend Down & Succession Strategy

Time-bound philanthropy and leadership transitions require clarity and intention. We guide foundations and donors through spend-down and succession strategy, aligning timelines, governance, and investments to ensure responsible transitions.

Funder Collaboratives

Complex challenges require collective action. We help design, launch, and steward funder collaboratives and pooled funds, aligning diverse partners around shared goals, strategies, and coordinated investment.

Grantee Capacity Building

Strong organizations drive lasting change. We support grantees beyond the grant through capacity-building, strategic guidance, training, and cohort facilitation — connecting leaders to resources that strengthen leadership, operations, and long-term resilience.
