The Onion Foundation is a private charitable foundation established in 2014 by Fritz and Susan Onion. It was created with the mission of encouraging conservation and stewardship of the natural environment and promoting music and the arts in the state of Maine.  Having grown up in Farmington, a small town in the western foothills of Maine, Fritz and Susan both value living in a rural community with access to the outdoors.

In 2004 Fritz co-founded the technology training company Pluralsight with three other colleagues. By 2013 the company had established itself as a high-growth, online subscription-based company training software developers and IT professionals world-wide. In 2014 Fritz and Susan created and endowed the foundation to support Maine nonprofits.

Both Fritz and Susan also serve on the advisory board of Pluralsight One, the philanthropic branch of Pluralsight, whose mission is to democratize technology skills world-wide.
