Foundation Source Strengthens Leadership in Philanthropic Solutions by Acquiring Pacific Foundation Services

Foundation Source Acquires Pacific Foundation Services

Foundation Source, a prominent leader in philanthropic solutions, has taken a significant step towards enhancing its service offerings by acquiring Pacific Foundation Services (PFS), a well-regarded foundation management organization located in San Francisco. This strategic acquisition positions Foundation Source firmly as a leading provider of philanthropic management services in the United States, with its total charitable assets under administration now exceeding $40 billion.

The transaction, completed on June 4, 2025, not only strengthens Foundation Source’s foundational management services but also expands the annual charitable funds it manages to over $2.7 billion. The acquisition will allow Foundation Source to provide even more comprehensive and tailored philanthropic solutions to its clients, ensuring they have access to cutting-edge, technology-driven tools that simplify the giving process.

Pacific Foundation Services has built a robust reputation for offering strategic philanthropic guidance, grant management, and advanced accounting services to some of the largest foundations in the Bay Area. This unique expertise will complement Foundation Source's existing offerings, particularly its technology-enabled services designed for private foundations. As a result, clients will benefit from not only enhanced philanthropic strategies but also from modern, cloud-based tools that promote cost-effective and impactful giving.

Joseph Mrak III, CEO of Foundation Source, expressed enthusiasm about the acquisition, stating, "We are thrilled to welcome the talented team at Pacific Foundation Services to Foundation Source. This integration will enhance our capability to support private foundations and their advisors through deep, strategic insights and tailored guidance. Our technology is second to none, providing a comprehensive solution for organizations dedicated to maximizing their impact."

The combined organization now offers an extensive range of advisory services, including program strategy and design, and deepening relationships with grantees through effective sourcing, grant structuring, and impact measurement. This partnership promises to enrich the philanthropic landscape for their clients, prioritizing streamlined operations that amplify both reach and impact.

Charles R. Casey, CEO of Pacific Foundation Services, is set to join Foundation Source in a leadership role. He remarked, "We are both mission-driven organizations focused on creating meaningful relationships and enhancing our clients' giving experiences. This collaboration represents an exciting new chapter that has the potential to leave a lasting positive impact on the sector."

Foundation Source's recent acquisition of Pacific Foundation Services is part of its broader strategy to grow and innovate within the philanthropic sector. Earlier this year, the company also acquired Giving Place, a platform dedicated to family office giving programs and private foundations, as well as Vennfi and PG Calc, which provide donor-advised fund sponsorship and planned giving solutions, respectively.

Foundation Source has established itself as a leader in offering enterprise-grade technology, administration, and professional services that address the unique needs of private foundations, donor-advised funds, planned gifts, and workplace giving. Lizzie Wintle, Director at GTCR, noted the strategic importance of this acquisition: "Pacific Foundation Services significantly broadens our reach among large private foundations and enhances the depth of support we can provide in terms of programmatic and grantmaking."

In conclusion, Foundation Source’s acquisition of Pacific Foundation Services not only solidifies its leadership position in the philanthropic sector but also opens doors for an even greater impact on charitable giving practices. As the firm continues to integrate modern technological solutions with philanthropic strategy, the landscape of charitable contributions and fund management is poised to evolve in response to the innovative capabilities that this partnership brings to the table.
