Launched a grant writing kit three weeks ago, still at zero revenue

I spent the last couple months building GrantKit, a set of templates and worked examples for writing grant proposals. The idea came from watching a friend who runs a small nonprofit lose forty hours to a proposal that got rejected for formatting reasons. That felt fixable.

So I built it, put up a landing page, and shipped. It's live. Revenue so far is zero dollars. Not low, zero.

I've posted in a few communities, tweeted into the void, and emailed maybe a dozen nonprofit folks I found through mutuals. A few polite replies, no sales. I honestly can't tell if the problem is the product, the copy, the price, or that I'm just invisible.

So I'd rather hear it straight from people who've been through this. What actually got you your first paying users? Was it one channel that worked, or just grinding every channel until something stuck? And if you look at what I made and think the whole premise is off, say so. That's more useful to me right now than encouragement.
