There is no right answer for this, but definitely, you need to have a 'hustle' aggressive approach when you're launching something new.

That means to dedicate some time to get in front of the right people. You can start by joining Facebook groups in your category, going to meetups (as a host and/or as a speaker), and create a Facebook group or a Slack channel for early adopters.

The important part is to be in front of as many eyeballs as possible and to build a community of users/supporters.
