Any recommendations about how to increase exposure?

Hey all, the last few weeks I've been working on Frozonic, a tool for freezing pull requests when certain things are configured.

I've been wondering how to give more exposure to the product, right now we're in beta and we're keeping a list of those very first initial users so that we can offer starters discount when we go fully live!

Unfortunately, there aren't that many companies or single users trying it out. I believe there's a good set of situations where the tools is useful, but I really want to give it more exposure, so that more people know about it.

Any recommendations about how to increase exposure?

Thanks in advance!
