I have recently built a tool to create animated flowcharts: https://flowyboard.com/. I was thinking that the moment I launch it and announce it in the hackernews as a post, it would explode!! I was naive! The reality is so damn difficult, even if there is no competitor for your tool! As a solo founder, doing my eveyday full-time job and working on my app in the weekends, doing natrual marketing takes time, But I guess that's the way. Now, if you know better ways, let me know. BTW, check the tool and give your honest feedback please.
