Follow-up (August 26, 2026): 501see has its first paying user, but distribution is still the problem
Hey IH. I posted here on May 13 about 501see, the nonprofit financial and grants research tool I’ve been building.
The biggest update is simple: I now have a paying user on the grant product.
That feels like meaningful validation. The core workflow is becoming clearer: search for foundations, inspect their historical giving and recipient portfolios, save promising funders, and manage them as prospects instead of immediately falling back to a spreadsheet.
The harder problem is still distribution.
I’ve spent time looking at Reddit, Facebook groups, technical publications, and SEO. Reddit has been useful for understanding how people talk about these problems, but it has not turned into a dependable traffic source. The directories and publications feel similar: useful to be listed in, but not something I can rely on for discovery.
So the current state is:
1. The product is useful enough that someone is paying for it.
2. The grant research workflow is much clearer than it was a few months ago.
3. I still have not found a repeatable way to get it in front of more nonprofit development teams, grant writers, or consultants.
That’s the main thing I’m trying to solve now. Not another feature. Distribution.
If you’ve sold a niche B2B product into nonprofits, where did your first real users come from? And which channels produced actual conversations instead of just impressions?
Getting the first paying user makes the distribution problem much more interesting.
I’d be curious whether the challenge is finding the right channel, or that the people encountering 501see don’t immediately see themselves as the buyer.
