A note from the founders

We created Skyline Foundation in 2000 with a deep sense of responsibility to return the wealth created through the internet company Yahoo! back to society. We bring our collective experience as a couple in the areas of engineering, education, tech, journalism, and nonprofits to the work of the foundation. We view the sole mission and everyday work of the foundation to be finding and funding organizations with inspired, innovative leadership whose missions align with the foundation’s values and vision for the future. We are grateful each day to work in partnership with the foundation’s small but mighty staff and its powerful network of grantees.

Gratitude & Hope

We are grateful for the leaders, organizations, and communities who invite us into their work and share their knowledge, vision, and hope for a more equitable future.

Justice & Opportunity

The fight for gender, racial, economic, and environmental justice is central to our work. We seek to move resources into expert hands in service to opportunity for all. Funding well-considered yet bold and venturesome ideas is an adventure we embrace.


We feel the fierce urgency of now. We believe in addressing problems at the root and shifting systems for the betterment of society. The foundation’s assets belong to humanity. We are temporary stewards – and there is no time to waste.

Curiosity & Humility

Listening to and learning from others is fundamental to our work. Humility means trusting that true expertise and inclusive solutions rise from the people closest to the problems we seek to address.

Trust & Partnership

We take seriously our responsibility to leverage our access, skills, and power to benefit others. We strive to be responsive, candid, and clear in our relationships, and honor our commitments, placing grantees at the center of all we do. We stand ready to help through flexible, long-term support, knowing that change takes time, persistence, and courage.
