Model & Strategy

Taproot Foundation engages the nation’s business professionals in pro bono services to support nonprofit enterprises in achieving urgent social change. Impacting critical issues like the environment, health, and education requires more than vision and passion. To succeed, social enterprises also require access to marketing, design, technology, management, and strategic planning resources. Taproot offers three core programs to increase nonprofits’ effectiveness through access to pro bono professional services.

The Services Grant Program directly matches volunteer experts from an array of fields with projects in need of support. The Advisory Services Program supports organizations to internally develop their own customized, high-impact pro bono outreach programs. The Advocacy Program joins leading foundations, universities, companies, coalitions and associations in collaboration to envision and design broader initiatives and movements built around donated services to effect social change.

Taproot demonstrates that pro bono service can be a reliable, high quality, cost-effective, and scalable resource for nonprofits, enlisting top talent from the marketing, tech, human resources, design and consulting fields to create meaningful impact.
