This selection of North American foundations features diverse organizations, primarily large non-profits and healthcare providers. Companies include Nemours Children's Health, a non-profit children's health organization, and the Gates Foundation, focused on improving global health and education. The Apache Software Foundation supports open-source projects, while Kamehameha Schools provides K-12 education and community programs for Hawaiian students. The Henry M. Jackson Foundation advances military medical research.
A notable pattern among these foundations is their broad geographic distribution across North America, with headquarters ranging from Jacksonville, Florida, to Seattle, Washington, and Honolulu, Hawaii. This indicates a decentralized approach to philanthropic and public service efforts across the continent.

Turn this list into pipeline
Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
