Thee Mustard Seed Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- Thee Mustard Seed Foundation does not accept unsolicited requests, so a cold application is not the route its filing describes; a small charity should look first for a genuine introduction from someone who already knows the foundation.
- Where the work fits its general-fund pattern of youth, homelessness, faith-based, education and social-service support, a request in the region of $90,000 sits at the middle of its grants, since half of its 54 grants to organisations were $90,000 or less, while about 8 in 10 fall between $12,000 and $350,000, a typical band rather than a ceiling.
- Its grants have mainly gone to Massachusetts, Connecticut, Illinois, Texas, Ghana and United Kingdom, but no geographic focus is stated, so location alone should not rule a charity in or out.
- Giving is heavily repeat: in its latest filing, 71% of its grant dollars to organisations went to organisations it had also funded in one of its two preceding filings, so newcomers should expect a relationship-led process.
- The filing gives no public application instructions or timing, so the sensible course is to wait for an invitation rather than plan around a deadline.
