The Thoma Foundation accepts Letters of Inquiry (LOIs) on a rolling basis from 501(c)(3) nonprofit organizations. We fund programs that provide promising new insights into the fields of art which we collect: Digital & Electronic Art, Spanish Colonial Art, Post-War Painting & Sculpture, and Japanese Bamboo. We value long-term relationships with grantees and encourage you to connect with us before submitting your inquiry.

You may submit an LOI on our SlideRoom platform linked below. If we are interested in learning more about your project, you will hear from us within 30 days with an invitation to submit a Complete Proposal. The Foundation reviews Complete Proposals quarterly on March 31, June 30, September 30, and December 31. We strive to respond within 60 days following review dates. Please keep in mind that the Foundation prefers 12 months’ notice before the start of a project.

Questions about our grant opportunities should be sent to All grant requests and Letters of Inquiry must be submitted through SlideRoom.
