One8 Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- One8 Foundation says it does not consider unsolicited grant proposals and may only periodically invite small proposals, so a relationship with the foundation is a more realistic route in than a cold application.
- Grants are limited to 501(c)(3) organisations, so confirm that status first.
- Fit matters: its stated themes are education (applied learning and STEM in K–12 and postsecondary settings, working with educators and schools in Massachusetts), Jewish community and Israel, community giving for local nonprofits helping individuals and families in need, and epilepsy research and care, and work outside these is unlikely to match.
- About 8 in 10 of its grants fall between $10,000 and $635,000 in the filings, and half of its grants across its recent filings were $50,000 or less, so a modest request near that median is the sensible size; the largest grant was $6,750,000, so that band is not a ceiling.
- In its latest filing, 85% of its grant dollars to organisations went to organisations it had also funded in its earlier filings, so new applicants should expect to be less familiar to it than its established partners.
