I think if you had a link in your profile, you could have probably reached half that number by now. Just look at all the comments!

In my case, most of the early adoption for my products have been through in-person interactions. Both B2B and B2C. I’m not sure what your product is, but to take a gander, I’d probably just ask friends who worked in startup or corporate jobs if I could stop by their office and show off what I was working on. Then I’d probably offer a trial to anyone who showed interest while I was there and offer to extend their trial if they find friends or colleagues who were interested in trying it out themselves. If you have a bit a flywheel effect through that, then you know you’re on to something.
