Grant Management Platform

Don't lose the grant to the paperwork.

GrantsIn checks every application against the funder's real requirements before it goes out. The missing form, the blown character limit, the unchecked eligibility box. Caught before a reviewer ever sees them.

The Problem

A polished application is not the same as a complete one. Funders check the second thing.

Grant work is scattered. Your EIN is in your inbox, your budget is in a Drive folder, your last application is in someone's downloads. You assemble it across a dozen tabs and hope nothing is missing.

The problem is what happens next. Applications get screened for completeness before anyone scores them. Wrong format, missing attachment, an eligibility box unchecked, and the work never gets read. A strong project loses to a paperwork error, every time it happens.

Federal applications can run well past 100 hours of work. A single missing form can end one before it is reviewed.

What GrantsIn Does

Built backwards from the submit button.

Most tools help you find a grant or write one. GrantsIn does the part no one else does. Before anything can be submitted, it checks your application against that specific funder's actual requirements. Every required field, attachment, limit, eligibility rule, and format.

It is exact.

A requirement either passes or fails. The check is not an AI guess and cannot make something up.

It is final.

If the application is not complete, it does not go out. No overriding past a missing requirement.

It shows its work.

Every flag links to the exact funder rule behind it, so you know what to fix and why.

That is the whole promise, and its limit. GrantsIn keeps you from losing the grant on the paperwork. It does not win it for you. Your narrative and your fit with the funder are your work. The boxes that get checked before anyone reads a word are ours.

Built From Inside the Problem

Built by a nonprofit that spent last Saturday on an SF-424.

GrantsIn comes from Humainority, a nonprofit that files its own grants. We are not watching this problem from the outside. We file the forms, we miss the deadlines, we lose the Saturdays. Every form we struggle with becomes a feature spec. The platform is built from inside the work, by the people who do it.
