We find your funders, write the applications, and hold every deadline. Foundation and corporate grants, done for you. Flat fee, never a cut of your award.
For food security and human services nonprofits, $500k to $5M budgets.

The problem
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
Foundations and corporate funders you qualify for. Each with its deadline, award range, and why it fits.
Full proposals and budgets in your voice, built on your real numbers. Two to four a month on a steady calendar.
We track every deadline so nothing slips, handle funder reports after a win, and send your board a short update each week.
Pricing

The full grant office
Standard rates after the founding period: $1,000 to $1,500 per application, $1,500 to $3,500 a month on retainer. Flat fee only. The GPA and AFP codes of ethics prohibit commission, and so do we.
About
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
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.
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.
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.
