Have you thought about how your solution differs to Appcues and Intercom Tours? Just curious, as my team tried to build a solution like this but struggled to differentiate in the noisy space that is visual onboarding tools
We just focus on launching a fun to use and intuitive app, that does one thing and it does it right.
I'd say just because there's Jira on the market, doesn't mean Trello has no room. Quite the contrary, I think more people use Trello on a day-to-day basis - and probably an average of about 5 features lol.
