The problem

Most nonprofits leave grants on the table.

The funding is there. The staff hours aren't. Researching funders, writing each one well, and tracking deadlines is exactly what we take off your plate, so your team stays on the mission.

How it works

A full grant office, without the hire.

Funder research

Foundations and corporate funders you qualify for. Each with its deadline, award range, and why it fits.

The applications

Full proposals and budgets in your voice, built on your real numbers. Two to four a month on a steady calendar.

Deadlines and reports

We track every deadline so nothing slips, handle funder reports after a win, and send your board a short update each week.

Pricing

Flat fee. Never a percentage of your award.

Founding-client pricing while we build our first case studies. Start small, scale when it earns its place.

About

A new practice, run to senior standards.

Mainstay Grants is new. We'd rather earn your trust than claim a history we don't have. So we do it differently.

Read real demonstration samples of our writing before you decide anything. Every statistic we submit traces to a real, named source. A person reviews and signs off on every application, and nothing is filed without your approval.

We use AI to research faster and draft sooner, the way good writers now do. The judgment and accountability stay human.

"Every number we send a funder traces to a real source. One invented figure would end this practice, so we never invent one."

Questions

Straight answers.

Do you use AI to write the applications?

As a tool, yes, for research and a first draft. A person then reviews every word, every figure is checked against a real source, and nothing is auto-submitted. Funders increasingly reject generic AI applications. Ours are human-led and specific to your work.

Do you ever work on commission?

No. You pay a flat fee, never a percentage of an award. The Grant Professionals Association and AFP codes of ethics prohibit commission, and we hold to that.

What is your track record?

We're a new practice. Instead of vague claims, we show you demonstration samples of our real writing, with founding-client pricing that keeps your first engagement low-risk.

Who do you work with?

US nonprofits in food security and human services, roughly $500k to $5M in budget, applying to foundation and corporate funders. We do not take federal or state contract work.
