Maddie's Fund
At a glance
Key takeaways
- Maddie's Fund supports work that keeps pets and people together, animal welfare research, leadership development and industry solutions and collaborations for dogs and/or cats, so it suits US-based 501c3 public charities and government animal well-being organisations working in this space.
- Aim low: about 8 in 10 of its 743 grants fall between $1,000 and $62,000, the median grant is $5,000, and half of all grants are $5,000 or less, though its largest grant was around $1,450,000, so most applicants should pitch a modest request.
- Specific named opportunities are capped too, with up to $10,000 for Maddie's Weekly Community Conversations Grant Award and up to $4,000 for the Animal Welfare Professionals community.
- Most funding is by invitation, as Maddie's Fund identifies potential applicants through year-round research and engagement, so this is a relationship-led funder; it also runs monthly opportunities such as Maddie's Pet Forum and Community Conversations (live or on demand) that groups can apply to directly, and 70% of its grant dollars went to organisations it had already funded in its two previous filings, so existing relationships matter.
- Individuals are not funded, and any applicant taken on must be ready to publish annual statistics (shelters must also publish their success benchmark and calculation formula) and report how funds were spent and the results.
