We believe that Small, deliberate steps can help us Achieve Audacious Goals

The Honnold Foundation envisions a world where all people have equal access to opportunity and live in balance with the environment. We believe in solar as a proven, environmentally sound solution to global energy poverty, and we award grants to bold and ethical organizations driving innovation in the solar industry.



Alex Honnold, Founder

Alex is a professional rock climber, best known for his ropeless ascents of some of the world's biggest rock walls. As a matter of principle and practicality, Alex lives as simply as possible. The Honnold Foundation is an extension of that ethic.


Maury Birdwell, Board Chair

In 2012, Maury and Alex created the Honnold Foundation while chatting in the car on the way home from a climbing trip. Their vision was simple: to improve lives and reduce environmental impact. Maury served as the Foundation's Executive Director from 2012 to 2018, and is now the Chairman of the Board. As a lawyer and climber based in Boulder, Colorado, Maury enjoys working with businesses, solving interesting problems, and going on climbing adventures all over the world.
