For GetMyMFA I ended up surprising myself seeing that people would discover the product from tech forums and FAQs.

I’d therefore recommend thinking where your users are on the web / what they are searching for and try to join active discussions where your product might be relevant.

PS: I just realized I’m trying to do exactly that in HN right now :D

That's great advice. When I started selling an Outlook add-in a couple decades ago some of the best traction I got was from a website dedicated to providing technical advice to Exchange admins. Go to where users who'd find your product useful congregate.
