Tidefall Foundation

Our Mission

We look for work that matters and people we trust to do it, then give them room to do it well.

Lasting change rarely arrives on a grant cycle. We fund with patience, not pressure — staying with good work long enough to see it through.

Where we direct our support.

Four areas guide our grantmaking. They overlap, and they will evolve — what connects them all is the question: what helps life endure?

Protecting the natural systems that sustain all life, from old growth to open water.

Strengthening the ability of communities to adapt, recover, and thrive.

Advancing our understanding of the systems we depend on and the changes they face.

Tools and innovations that reduce humanity's footprint on the systems we share.

We use the full range of tools available to a foundation, choosing the one that fits the work rather than asking the work to fit the tool.

Grants

Direct funding given freely, with no expectation of return — including multi-year commitments that give work the time it needs.

Funding that may come back if a project succeeds, then goes to work again elsewhere.

Program-related investments

Loans and ownership stakes in work that can sustain itself over time.

Backing that helps others lend to projects they might otherwise pass over.
