If I may ask: on what subreddit(s) did you post? Was it a normal post where they allow self-promotion, or sponsored/ad one?

Almost none of them allow self-promotion. Exception are those like /side-projects where it's kind of its purpose, but very unlikely to attract real users.

I believe that customer came from /leadership. Smaller one, but well targeted for me.
